HiWe are facing a problem while trying to read data out of QSPI flash in memory mapped mode shortly after programming a page in DMA mode. We see that the read data is corrupted / unexpected altough flash hast he correct data. Our steps to reproduce t...

How can I enable the parity check in the SRAM 2 of the STM32L4?Is there a HAL function?

Do someone from ST could check if the SRAM2 parity enable bit can be reset to 0 (0 = parity check enabled!) in the STM32L4A6ZG?The code in not working: FLASH_OBProgramInitTypeDef optionBytesInit = {0U}; HAL_FLASHEx_OBGetConfig(&optionBytesInit); o...

I don't set anything actively during programming, but we use IAR (V8.20) and HAL (V1.8.3).The value of the option register (FLASH->OPTR) is 0xFFEFF8AA.

FLASH_OB_UserConfig() is a static function. I use HAL_FLASHEx_OBProgram() which calls FLASH_OB_UserConfig(): HAL_FLASHEx_OBGetConfig(&optionBytesInit); optionBytesInit.USERType |= OB_USER_SRAM2_PE; optionBytesInit.USERConfig &= ~FLASH_OPTR_SRAM2_P...
