disco_l475_iot1 don't confirm MCUBoot slot-1 image #25010

nandojve · 2020-05-06T02:54:06Z

Describe the bug
When build UpdateHub for disco_l475_iot1 the app don't confirm the image.

To Reproduce
Steps to reproduce the behavior:

clone https://github.com/UpdateHub/zephyr/commits/topic/uhu_wifi
set variables at prj.conf
CONFIG_UPDATEHUB_WIFI_SSID="wifi network"
CONFIG_UPDATEHUB_WIFI_PSK="password"
west build -b disco_l475_iot1 samples/net/updatehub
sign image
~/<zephyr_home_dir>/bootloader/mcuboot/scripts/imgtool.py sign --key ~/<zephyr_home_dir>/bootloader/mcuboot/root-rsa-2048.pem --header-size 0x200 --align 8 --version 1.0.0 --slot-size 0x6C000 ~/<zephyr_home_dir>/zephyr/build/zephyr/zephyr.hex ~/<zephyr_home_dir>/zephyr/build/zephyr/zephyr-1.0.0.hex
west flash --hex-file build/zephyr/zephyr-1.0.0.hex
See error

Expected behavior
boot_write_img_confirmed() executes properly on main.c

Impact
MCUBoot applications don't work.

@nandojve Is this TLS enabled?

nandojve · 2020-05-09T14:29:00Z

Hi @parthitce, if you are referring to UpdateHub, yes, it works with/without DTLS.
Take look at https://github.com/zephyrproject-rtos/zephyr/tree/master/lib/updatehub and https://github.com/zephyrproject-rtos/zephyr/tree/master/samples/net/updatehub.
You can get more info at https://updatehub.io/

About MCUBoot, you must use your own certificate to sign images.
https://github.com/JuulLabs-OSS/mcuboot/blob/master/docs/readme-zephyr.md

To get MCUboot working you need SoC flash stuff working properly, as far I know. With that, you can get UpdateHub working if you have a network interface. You can use a wifi shield like ESP_8266 or any other available. The shield is basically wifi config + board overlay.
https://github.com/zephyrproject-rtos/zephyr/tree/master/boards/shields/esp_8266

This way, you don't need a full ethernet available to test it, only a serial 115200 with RX/TX.

ABOSTM · 2020-05-11T08:58:27Z

Hi @nandojve,
It would be interresting to determined whether issue comes from wifi as opposed to ethernet.
So I tried to run the samples\net\updatehub\ from original zephyr on STM32F429 which support Ethernet.
I followed instructions from samples\net\updatehub\README.rst
Unfortunately after spending about 1 day and a half, I am unable to have updateHub image running with docker.

$ docker run -i -p 8080:8080 -p 5683:5683/udp --rm updatehub/updatehub-ce:latest
Unable to find image 'updatehub/updatehub-ce:latest' locally
C:\Program Files\Docker\Docker\resources\bin\docker.exe: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).

I suspect Proxy issue, I tried to set proxy environnement variables, and also tried to add proxy to config.json, but it doesn't help.

I looked for precompiled updateHub image for windows to download, (so that it could be available locally) but I could not found it.
I also tried to recompile it, but I face again connection issue when installing Packr utility:

$ go get -u github.com/gobuffalo/packr/packr
go: github.com/BurntSushi/toml@v0.3.1: Get "https://proxy.golang.org/github.com/%21burnt%21sushi/toml/@v/v0.3.1.mod": dial tcp [2a00:1450:4007:816::2011]:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

Would you be able to test on your side the same: From original Zephyr repo, on any STM32 board with Ethernet (instead of Wifi) ?

If you have network running and flash works with MCUboot you will be able to reproduce above steps. If you have any trouble, please, let me know!

carlescufi · 2020-05-12T17:29:29Z

@nvlsianpu is this related to the confirmation bug in mcumgr that you detected the other day?

nvlsianpu · 2020-05-13T07:25:59Z

@carlescufi ^^ not related to that one (was issue caused by different NCS partition manager configuration).

@nandojve Is this bug is regression to something which used to work before, or it was newer tested on this SoC? Confirmation problems suggest me an issue with the flash write operation to write area, as confirmation is just the write of proper data to certain flash addresses.

ABOSTM · 2020-05-13T09:19:43Z

Hi @nandojve ,
After you provided me the package I could not generate, I continued on Ethernet use case on nucleo_f429zi.
I finally get IP address with DHCP (I had issue with my PLC to connect to my internet box)
But unfortunately I spent a lot of time and I am stuck again:
my updateHub server is accessible from web browser running on the same PC running the server,
but the server is not accessible from another PC even if running on the same local network.
In other word, updatehub server is isolated and cannot be accessible by any external device.

As I understand, generally speaking, updatehub is working with ESP_8266 shield.
Would it be possible for you to test updateHub disco_l475_iot1 with this ESP shield on ?
(Deactivating disco_l475_iot1 wifi module, and enabling ESP shield)

nandojve · 2020-05-13T12:50:59Z

Hi @ABOSTM, by the docker command line you must have UDP port 5683 open to work.
If for some reason this port is blocked you can't communicate with docker service.

Anyway, my problem to advance with disco_iot is related to the logs:

[00:00:00.539,000] <inf> main: Confirming the boot image
[00:00:00.539,000] <err> main: Error to confirm the image  <<<<<<< PROBLEM
uart:~$ Connected <<< WIFI got connected >>>>

That message is printed by the following code at samples/net/updatehub/main.c

	/* The image of application needed be confirmed */
	LOG_INF("Confirming the boot image");
	ret = boot_write_img_confirmed();
	if (ret < 0) {
		LOG_ERR("Error to confirm the image");
	}

So, my problem is, boot_write_img_confirmed need be OK to system work. It seems something related to flash on disco_iot. This issue you can check without UpdateHub-CE be present. Be sure trhat NET_CONFIG_SETTINGS option is false. Depending the code you are looking my be necessary adjust it on zephyr/lib/updatehub/Kconfig.

UpdateHub@6db1c5a

About WIFI, I have both es-WIFI and ESP_8266 working, so yes, I can test and switch if necessary.

ABOSTM · 2020-05-13T14:48:21Z

Hi @nandojve ,
I intend to put a debugger to understand why boot_write_img_confirmed() return is not OK, to know which step fails with which error code ... This is why I tried to get updateHub up and running.
If you know a way to reproduce the issue without the server, please let me know .
For example, would it be possible to flash the update image ( which one exactly?? including probably the necessary header describing the image ...) to the flash, so that I could be in the same state than after updateHub would have written flash with the update image? and thus be able to reproduce the issue.
This suppose writting the update image was fully successful ..

@nvlsianpu I never got UpdateHub working on that board. I've been raising issues related with hope to get disco_iot working at some moment. My feeling is that solving the boot_write_img_confirmed (this issue) and assuming flash write is OK probably UpdateHub will start to works.

@ABOSTM it is mandatory apps confirm the image on first boot otherwise MCUBoot will must roolback on next reboot. I think this is not fully addressed on current MCUBoot samples on Zephyr. The consequence is we can't see regressions or even know that MCUBoot is 100% functional and supported.

My suggestion is add boot_write_img_confirmed at hello word targeting to MCUBoot (CONFIG_BOOTLOADER_MCUBOOT=y) and debug it. If boot_write_img_confirmed fail you can experiment board enter on a infinite reset loop because there isn't a plan B image. Take that on consideration because isn't a bug.

@nvlsianpu Is there a regression test to check boot_write_img_confirmed requirement?

ABOSTM · 2020-05-14T07:02:27Z

@nandojve ,
Following your proposal, I test disco_l475_iot1 ,
I erase full flash, then flash MCUBOOT, then flash Helloworld example (signed image) with call to boot_write_img_confirmed()
But I did not face issue, function returns 0 wich is good:

Hi @ABOSTM thank you for the feedback!
Could you confirm SHA that you tested?

ABOSTM · 2020-05-14T15:15:57Z

nandojve · 2020-05-15T02:17:43Z

@ABOSTM I continue saw flash not be confirmed on your SHA and on the last one.

The only difference that raise a flag for me was that:

Your Primary image: magic=unset, swap_type=0x1, copy_done=0x3, image_ok=0x1
mine Primary image: magic=good, swap_type=0x1, copy_done=0x3, image_ok=0x3

Below the procedure that I believe get last version of everything to make sure environment is not poisoned.

Please, add #25333 on top of master if not merged yet.

Hi @nandojve ,
I reinstalled Zephyr from scratch (e550302),
I merge your modification of hello world example.
I build and flash MCUBoot , then build and flash example,
and again it is working fine:

There is 1 thing you did not mention in your procedure: recompiling MCUBoot and flashing it?
Did you just omite to mention it or you didn't do it?
I may be worth to give it a try.

otavio · 2020-05-18T12:35:24Z

@ABOSTM is there any lower level debugging information which might help to spot what is different from your setup?

nandojve · 2020-05-18T13:55:24Z

Hi @ABOSTM

There is 1 thing you did not mention in your procedure: recompiling MCUBoot and flashing it?
Did you just omite to mention it or you didn't do it?
I may be worth to give it a try.

I simple omit, but I built MCUboot and flash it first same week.
I'll give another try with latest.

Anyway, could you help to understand why the difference?
Your version
[00:00:00.006,000] mcuboot: Primary image: magic=good, swap_type=0x1, copy_done=0x3, image_ok=~~0x3~~ 0x1
Mine
[00:00:00.006,000] mcuboot: Primary image: magic=unset, swap_type=0x1, copy_done=0x3, image_ok=~~0x1~~ 0x3

What make that image_ok=0x3 instead 0x1? Could be this the reason I can confirm image?

NOTE: Update comment with right flags.

ABOSTM · 2020-05-18T15:58:25Z

I am not an MCUBoot expert, but I found those definitions

#define BOOT_FLAG_SET       1
#define BOOT_FLAG_BAD       2
#define BOOT_FLAG_UNSET     3
#define BOOT_FLAG_ANY       4  /* NOTE: control only, not dependent on sector */

Then I figure out that after a fresh flashing of images, the 1st boot displays image_ok=0x3 and then all further reboots (manual reset) display image_ok=0x1
So the fact you have image_ok=0x3 is good.
And It makes sense to me as the change is done by the call to boot_write_img_confirmed(), which will set image_ok=1 ... after confirmation.

But it still doesn't explain why you are not able to confirm the image.
I send you both images I generated (MCUboot and hello word application).
Can you start by a fullerase of the flash (if needed you can use CubeProgrammer https://www.st.com/en/development-tools/stm32cubeprog.html)
And then flash both image, It should work !!!
Then you can try to mix:
My MCUBoot image + Your application
and then Your MCUBoot + My application
It is important to make a full erase of the flash between each test.

nandojve · 2020-05-19T03:49:40Z

Hi @ABOSTM,

At first, I did another try with lastest Zephyr version and your signed image, both without success.
So, move to install stm32cubeprog, update st-link version from 18 to 26, first erase full + flash with error. I repeat the process and got success. Than, write my hello image using west and got the image confirmed.

I remember that I lost the board sometimes, usully ctrl+C when using west. The west was not able to write anymore. The solution was cp *hex or bin to mounted unity and get board running again.
Not sure if that can cause flash write problem.

I think we discover the way to make board works, need flash MCUboot using stm32cubeprog with full chip erase. With that, I can move forward and I think this issue can be closed.

Question: Is there a way to flash with full erase from command line on linux?

Just for record: I give some UpdateHub runs and get below:

When I put UpdateHub to run I got some connection instability and was need increase TCP/IP buffers. After some attempts I got

Using es-WIFI

Hi @nandojve ,
Good news !!
I don't know exactly what appends in your flash, but maybe previousoperations leave some images header in the secondary slot or in scratch area which make MCUBoot confused.

Question: Is there a way to flash with full erase from command line on linux?

It is possible to use CubeProgrammer with command line (CLI).
I nerver use it by you can found information in the documentation:
https://www.st.com/resource/en/user_manual/dm00403500-stm32cubeprogrammer-software-description-stmicroelectronics.pdf

It think it should also be possible to use OpenOCD or PyOCD do full erase the flash. But I am not sure Zephyr propose such option.

utzig · 2020-05-19T10:29:20Z

I don't know exactly what appends in your flash, but maybe previousoperations leave some images header in the secondary slot or in scratch area which make MCUBoot confused.

Confirming does actually write the confirmed flag to the primary slot, so probably there was some garbage there already (not previously erased!?).

Question: Is there a way to flash with full erase from command line on linux?

I use: https://github.com/stlink-org/stlink. st-flah erase for mass erase, and st-flash write <bin-file> <address> for write (preceeded by sector erase).

nandojve · 2020-05-19T12:33:47Z

Thank you guys!
Now I need to do some homework.

nandojve · 2020-07-22T02:01:30Z

Hi @ABOSTM , I open this issue again because I got same problem with zephyr-v2.3.0-1218.

If I do full chip erase and flash zephy_MCUBoot.zip and zephyr-1.0.0_Signed_HelloWorld.zip using cubeprogrammer on Windows, the system works.

This process is valid on Linux using the Utzig suggestion https://github.com/stlink-org/stlink and st-flash erase command followed by west flash zephy_MCUBoot and west flash --hex-file zephyr-1.0.0_Signed_HelloWorld.

Changing MCUBoot for the current version still system working. The system stop to work when I flash any application from main repository. To put system running I need execute again st-flash erase but only your app zephyr-1.0.0_Signed_HelloWorld confirming the boot image.

Note: Once the problem happen even your image don't works without a full erase.

ABOSTM · 2020-07-22T07:27:48Z

Hi @nandojve ,
If I understand correctly, it seems there is a regression.
Regression is not in MCUBoot but in application.
Regression occurs between the time I created zephyr-1.0.0_Signed_HelloWorld.zip and now.

So I suggest to make dichotomy (git bisect) to determine which commit cause the regression.

nvlsianpu · 2020-09-08T09:04:25Z

Error to confirm the image

It seems that Zephyr-2.4.0-rc1 images doesn't confirm and corrupt the whole system. When flash a bad image (eighth test) the system run normally when revert to old firmware.

I confirm that after rebase to 2.4.0-rc1 updatehub doesn't confirm the image and stay rebooting. When I disable image confirmation boot_write_img_confirmed() the system still rebooting. It seems another regression but need more investigation. Because of all this I not able to run UpdateHub using esWiFi on disco_l475_iot1. I'll try run more tests and expects report early next week.

nandojve · 2020-09-19T20:27:42Z

@nandojve would you mind rebasing https://github.com/UpdateHub/zephyr/commits/topic/uhu_wifi so we can have a test on recent zephyr version ?
Txs

Rebased on top of 2.4.0-rc2. The 28b9617 is full functional here at ETH/WIFI/MODEM.
Don't forget to change configs:

at prj.conf
CONFIG_UPDATEHUB_SERVER="<IP>"

IP: can be on local network or internet. DNS names will be resolved.
This way a docker machine can run updatehub-ce at any place.

at overlay-wifi.conf
CONFIG_UPDATEHUB_WIFI_SSID="<SSID>"
CONFIG_UPDATEHUB_WIFI_PSK="<PASSWD>"

Can you describe clear operation sequence required to reproduce the file: eg:

flash mcuboot of version xxx and application
upload image of , set it to test...
...

I have only nRF52xxdks boards so want to reproduce yours results using smp_svr sample. So fare I can't.

nandojve · 2020-09-21T13:30:05Z

Hi @nvlsianpu , the project that I try run is UpdateHub@74ae362

I sign the image and upload with west flash --hex.... All that I reported on the old post is related to the image at slot-0 after flash, and the above commit is the new firmware. I think you don't need use smp_svr because problem shows with west flash.

old MCUboot(bootloader)
zephy_MCUBoot.zip

old firmware
zephyr-1.0.0_Signed_HelloWorld.zip

Originally posted by @ABOSTM in #25010 (comment)

Sequence is inside old post, try resume the first test, eighth and nine:
st-flash erase
flash old bootloader
flash old firmware
result: OK

Eighth test: Full erase, new bootloader, old firmware, bad image, old firmware: Ok
st-flash erase
flash new bootloader
flash old firmware
flash BAD firmware (image without sign)
flash old firmware
result: OK

Nineth test: Continuing eighth test: new image, old firmware: Fail
flash new firmware
flash old firmware

So, when I flash the new firmware at slot-0 using west it fail to confirm the image and somehow compromise the whole system. I mean, a old firmware (that always works) only confirm after full chip erase. I believe it can be something related only to ST SoCs.

I start to think this is the key related to the problem that I've been facing with ST SoC that MCUboot don't swap slot-1 to slot-0 keeping updatehub on a infinite upgrade loop.

@nandojve What you men by new bootloader, old bootloader, new firmware and old firmware?

nandojve · 2020-09-23T12:15:38Z

@nvlsianpu it is about versions
old: v2.3.0-rc1-122
new: v2.4.0-rc1-264
