What flow control?
Because putty is not showing anything.

No flow control. Maybe you selected the wrong com-port?

I opened both at the same time with putty

Here is a list of things that you could try to solve it:

  • check wiring
  • check the settings of dev cube
  • check log of dev cube during flashing
  • try a different serial probe

DevCube said it successfully flashed it. Is it still possible that it was not flashed properly?

Please make sure you are using version 1.8.3 of Devcube. Older versions have a issue.

Where can I find version v1.8.3?
I have only found v1.8.4 on their website?

I used version v1.8.3 and I still was not able to get a serial console.

Used v1.8.4 and the latest FW from https://github.com/openbouffalo/buildroot_bouffalo/releases/tag/v1.0.1 but i also didn't get a working serial console (neither 2000000 Bd or 115200 8N1 etc is working) for Linux on GPIO 16/17 (Pin 31/32), just get carbage on GPIO 14/15 (Pin 1/2) used for the programming 🤷

1.8.4 is broken with the current buildroot. You have to use 1.8.3.

only 1.8.4 is available from https://dev.bouffalolab.com/download :(

@Fishwaldo thnx a lot, with 1.8.3 i was able to get "something" from GPIO 16/17 (Pin 31/32), but it's still just carbage. Seems my USB-to-Serial Converter based on CP210x isnt capable to operate above 115200 Bb...
According to the data sheet a FT232 based could do up to 3M Bd, but Amazon just listed converters with FT232BL/RL which are only able up to 1M Bd ... any suggestions for a working converter capable for 2M baud? thnx

Bought a CH340G based USB-to-Serial Converter at Amazon for 5 bucks this is able to operate at 2.000.000 Bd :woohoo:

Which one? Because mine also does not support 2.000.000 Bd. I managed to patch the firmware to run at 115200 Bd, but having a faster serial port might be more convenient.

I used version v1.8.3 and I still was not able to get a serial console.

were you able to get it working because I am unable to get anything on the serial port 14/15 seems to work but 16/17 isn't working using CH340G based adapter

flashed it with v1.8.3 via GPIO14/15 (Pin 1/2) in boot mode, afterwards got the serial console for linux via GPIO16/17 (Pin 31/32) ...

that looks not right, re-download the images from https://github.com/openbouffalo/buildroot_bouffalo/releases/tag/v1.0.1 and try it again. i didn't got that error during flashing. maybe you've mistaken m0_lowload_bl808_m0.bin with d0_lowload_bl808_d0.bin or vice versa?

Have the same problem on sipeed M1s. Tried listening on all the UART pins from separate usb to uart board. Tried flashing versions from here https://github.com/openbouffalo/buildroot_bouffalo/actions/runs/4754065203, check everything 3 times. Nothing seems to help, just constantly repeating [MBOX] messges about Unhandled Interrupts on E907 uart.

EDIT: solved
Turned out i was writing IOT firmware at the wrong address. I didn't change it to 0x800000 from 0xD2000 of sipeed example.

To use the CP210x, use the CP21xxCustomizationUtility to change the baud rate to 2000000.

I had the same problem on my Sipeed M1s (only the M0 core was showing something, while D0 was just completely silent), I managed to solve it by using the old version of DevCube:
