Hi all,i have an issue with an STM32-H7A3, which is going into hard fault, when calling a function, which is moved to the ITCM-RAM.I have defined a section for ITCM-RAM in the Linker-Script: _siitcmram = LOADADDR(.itcmram); /* size of ITCM-RAM */ ....

Hi Folks,I have an issue with the RS485 Driver Enable Pin with the USART6 on an H7A3 (Nucleo).The Perhiperal is set up in CubeMX with "Hardware Flow Control (RS485) enabled.I have developed a driver using the Low Level functions.The Peripheral is set...

Hi folks,I have a Projekt on an STM32G431CBU. The programm runs without erros in DEBUG mode as well as in RELEASE Mode, when I flash it from the CubeIDE. For me this means the binaries are OK.But if I want to flash the ELF-Files to the MCU with Cube ...

Okay and Oh my gosh ... I found the root cause.Thanks to your hint with the Memory watchpoints, I could trace back where the one value in the ITCM was changed.That value corrupted a function in the ITCM (that's why the flash is read only ...), which ...

Thanks for that hint! It definitively helped me to debug! I did not know before, that I can set breakpoints there, too!I have not yet found the issue, but sooner or later i will catch that bugger! It makes very easy to find out where a specific memor...

Thanks @TDK i tried your code and that worked. I can see the ITCM-RAM is filled with 0x00 in the memory viewer.This means: when I revert that change and copy the flash contents again, the ITCM is filled correctly. I guess I have to search the root ca...

thanks for the hint with the C-file, I'll try that ...

some additional info: it looks like the copy function is working.This is the content of the FlashCode in Flashand this is the content of the ITCM-RAM after startup:ITCM-RAMa visual comparison tells me the contents are almost identical, except one wor...
