[not chibios] stm32cube bug how to get help from ST?

Postby russian » Mon Jan 30, 2023 1:52 pm

stm32cube software is unable to program over 512Kb of binary into STM32F767ZG which is a 1MB part due to wrong identification as 2MB part

(problem: it does not erase sector 12 prior to writing at at address 0x08000000)

We first reported this back in 2021 as https://github.com/STMicroelectronics/S ... /issues/11 and https://community.st.com/s/question/0D5 ... mb-stm32f7



best we got so far is "i have also transmitted your issue to our development team with the internal reference 120183"



looking for ideas on how to make progress with this issue?

hi,

You could use OpenOCD for programming I think.

It's about DFU which OpenOCD does not support :(

The only hope is ST then, I will send this link to somebody in the MCU division but don't expect immediate reactions.

Hello,

have you tried dfu-util ? :dfu-util

works well for USB-DFU, packaged in ubuntu repository : apt install dfu-util

exemple to flash every STM32 with eeprom @0x8000000 :

Code: Select all

dfu-util -d 0483:df11 -c 1 -i 0 -a 0 -s 0x08000000:leave -D firmware.bin


Alexandre
