Resolved! Using printf to output a large array cause the program to freeze
When I use the UART_Printf example to output an array of size 1024 (or larger) via printf, the program seems to freeze and doesn't output any information after being downloaded to the STM32WB55 Nucleo board. However, when I reduce the array size to 6...
Resolved! STM32N6: MPU config, code execution - why not at 0x70000000?
I try to build a code example where I can execute directly from external OctalSPI flash.I use HAL project "XSPI_NOR_MemoryMapped_DTR" as reference and starting point:It works fine: I can write (flash) and read back external QSPI memory. I can also ex...
Resolved! STM32N6 Hard_Fault when accessing TCM
Hello,I have a problem with STM32N6. When trying to access any TCM (ITCM/DTCM) the CPU immediately crashes to the Hard_Fault. Do the TCM memories need to be explicitly enabled or something? From my experience from STM32H7, it was never needed. I've l...
HSI to PLLCLK set to max frequency causing hard faults
Hey, I'm having some issues with setting up clocks for my STM32F411CEU custom board with HAL.Using PLLCLK from HSI ends up with Hardfault, around where RCC is being configured.The only way I don't get hardfaults is:1) if I set System Clock Mux to HSI...

Resolved! DTCM NOT Losing Contents On Power Off
I'm using an STM32H747XI Discovery board for testing. I seem to have the opposite problem of everyone else, my DTCM value is NOT clearing upon losing power. I have the following in my LD script: MEMORY { ... /* Put NOINIT at the top of the DTCM bloc...
