cpu/stm32: fix riotboot settings for L4 and WB #19618

gschorcht · 2023-05-19T00:51:26Z

Contribution description

This PR fixes the riotboot configuration for L4 and WB.

The family is not called stm32l4 or stm32wb but l4 and wb. That is, the riotboot configuration didn't work at all. Furthermore, a minimum RIOTBOOT_LEN of 0x2000 is required for L4.

Found when investigating the compilation errors for bootloaders/riotboot_serial in PR #19576.

Testing procedure

Green CI.

Use the following commands:

BOARD=nucleo-l496zg make -C tests/riotboot info-debug-variable-RIOTBOOT_HDR_LEN
BOARD=p-nucleo-wb55 make -C tests/riotboot info-debug-variable-RIOTBOOT_HDR_LEN

In master these commands give

0x400

With this PR these commands give

0x200

as expected.

Use the following commands:

BOARD=nucleo-l496zg make -C tests/riotboot info-debug-variable-RIOTBOOT_LEN
BOARD=p-nucleo-wb55 make -C tests/riotboot info-debug-variable-RIOTBOOT_LEN

In master these commands give

0x1000

With this PR these commands give

0x2000

as expected.

I tested tests/riotboot with this PR on nucleo-l476rg and p-l496g-cell02: it works for both. But it also works on master so maybe I'm not testing the right thing ?

I tested tests/riotboot with this PR on nucleo-l476rg and p-l496g-cell02: it works for both. But it also works on master so maybe I'm not testing the right thing ?

It works since it used the default value of 0x400 for RIOTBOOT_HDR_LEN set in cpu/cortex_common/Makefile.include. You can use

BOARD=nucleo-l496zg make -C tests/riotboot info-debug-variable-RIOTBOOT_HDR_LEN

to verify.

gschorcht · 2023-05-22T15:23:59Z

I have changed as suggested and squashed it directly.

To check you should use the following commands:

BOARD=nucleo-l496zg make -C tests/riotboot info-debug-variable-RIOTBOOT_HDR_LEN
BOARD=p-nucleo-wb55 make -C tests/riotboot info-debug-variable-RIOTBOOT_HDR_LEN
BOARD=nucleo-l496zg make -C tests/riotboot info-debug-variable-RIOTBOOT_LEN
BOARD=p-nucleo-wb55 make -C tests/riotboot info-debug-variable-RIOTBOOT_LEN

You should observe the wrong values are given in master.

On L4 the number of IRQs varies from 83 (L412) to 95 (L4R5 and the like). So 0x200 is enough in all cases.

I tested the values are correct following #19618 (comment)

Hmm, Murdock spotted a problem with nucleo-l4r5zi

Due to the bug, RIOTBOOT_LEN wasn't set to 0x2000 here

RIOT/cpu/stm32/stm32_riotboot.mk

Line 44 in 8408d69

RIOTBOOT_LEN ?= 0x2000

but in cpu/cortexm_common:

RIOT/cpu/cortexm_common/Makefile.include

Lines 73 to 77 in 8408d69

    
           ifneq (,$(filter usbus_dfu tinyusb_dfu,$(USEMODULE))) 
        
             RIOTBOOT_LEN ?= 0x4000 
        
           else 
        
             RIOTBOOT_LEN ?= 0x1000 
        
           endif

Therefore, RIOTBOOT_LEN was set to 0x4000 in case usbus_dfu or tinyusb_dfu are used. It seems that we also need to deal with this case for L4 and WB.

Therefore, RIOTBOOT_LEN was set to 0x4000 in case usbus_dfu or tinyusb_dfu are used. It seems that we also need to deal with this case for L4 and WB.

However, I wonder why we should increase RIOTBOOT_LEN to 8 KByte for all WB and L4 boards, when it worked with the bug even with only 4 kByte, especially for MCUs with only 64 kByte or 128 kByte of flash. The problem appeared only with stm32l496g-disco, because it must use additionally the module periph_lpuart and 4 KByte as RIOTBOOT_LEN are just 200 byte too little.

On the other hand, I'm not sure whether it would make sense to define RIOTBOOT_LEN on board level.

gschorcht · 2023-05-23T15:26:32Z

If I'm right, for WB family a RIOTBOOT_LEN of 0x1000 is definitely wrong since WB MCUs have a flash page size of 4 kByte so that the minimum RIOTBOOT_LEN has to 16 kByte to get a multiple of 4 kBytes when dividing total_flash_size - RIOTBOOT_LEN by 2.

The family is not called `stm32l4` or `stm32wb` but `l4` and `wb`. That is, the `riotboot` configuration didn't work. A minimum `RIOTBOOT_LEN` of `0x2000` is required for WB.

gschorcht · 2023-05-23T16:18:39Z

I have changed it back for L4 so that RIOTBOOT_LEN is set to the default values as defined in cpu/cortexm_common/Makefile.include. I fixed RIOTBOOT_LEN for WB. The problem with stm32l496g-disco is solved on board level.
