Hello everyone,I'm working on an STM32L431-based custom board, and I’ve encountered some very strange behavior that I can’t seem to explain. I have two variables pointing to different memory regions (SRAM and RAM), but when I modify one variable, bot...

Hello,I'm currently working on a project using the STM32L431CCTx microcontroller from the STM32L4 series. My goal is to retain specific variables in SRAM2 across MCU resets to maintain state and ensure data integrity using a CRC mechanism. However, I...

I have the NOLOAD on that are in my linker file, .ram2 (NOLOAD): I also tried adding this for test purpose, I added this to my linker .no_init : { *(.no_init) } > RAM then created a variable in that section to store it in no-init. And that...
