MCU STM32L562: With initialising the UART using HAL_UART_Init() the UART-communication is not working. Calculating the BRR like shown in the reference manual gives a working BRR-Value. Is the HAL_UART_Init() not intended for setting the BRR ?

The Project was migrated from STM32L4 to STM32L5. The Baudrate setting with HAL_UART_Init() works fine with L4 MCU. With L5 MCU it returns with an HAL_UART_ERROR_NONE too.

reg addr's for GTZC_TZSC_MPCWMxANSR GTZC_TZSC_MPCWMxBNSR

The doc and SVD file don't have a reg at offset 0x44 (GTZC_TZSC_MPCWM3BNSR).Since GTZC_TZSC_MPCWM3ANSR @0x40 exists, via symmetry I would expect B also at 0x44.The doc does say this:GTZC_TZSC external memory x non-secure watermark register 1(GTZC_TZS...

Single digit year in date code may be inadequate

The STM32 have a 3-digit date-code timestamp, in YWW format, with single-digit for year.Given the rolling 10-year longevity commitment, this may be not adequate to uniquely identify the manufacturing year, e.g. in light of ES0204 Rev 10 2.3.8 (The d...

Resolved! LED LD2 on STM32h745ZI-Q Nucleo 144 board not working

Sorry this is a very simple question but somehow LED LD2 just won't work on STM32h745ZI-Q nucleo 144 boards. As per the manual "UM2408 STM32H7 Nucleo-144 boards", the LD2 is connected to PE1 (by the way, I tried PB7 as well as the older one may on th...

ADC channel 12 less accurate than the other ?

Hello,Since two year, I am experiencing an issue with the ADC_CHANNEL_12 (pin PC12) of my STM32F767. I suspect it's a hardware issue coming from the MCU. a stable offset is added (randomly change each time I reboot the STM)this read value (via DMA) i...

Can I find the end of memory in a bin file?

Hello,Currently, the generated binary file is 1 MB but with 96% of '0'.Obviously, it's quite long to transfer via CAN to update the firmware, mostly for 'nothing'.I can see that the 'end' of my code is: 1000 0000 0100 0000 4078 7d01 0000 0000Is it...

Resolved! Timer initialisation to *not* set the ARPE bit ?

I would like to know what is the correct way to disable a timer’s ARR preload function using the HAL library ? And once that’s done, does the ARPE bit stay low for the whole runtime, or does it have to be cleared again regularly or after specific eve...
