I'm attempting to enable the SRAM2 parity bits on an STM32L552, and any time I call HAL_FLASH_OB_Launch, the chip hangs. I've also tried directly setting the OBL_LAUNCH bit in the NCSR register with the same results.I've looked through some of the L...
We have a project that works just fine using STM32L071RBT (compiler 5.0.6 build 960). As part of the project we erase a portion of the flash and then reprogram it for the fota, which again works great.I then branched the project to make another varia...
SWAP_BANK for the STM32L552 is a bit in the eeprom, but we want to swap the flash banks in an own bootloader dynamically and do not want to expire the eeprom's lifetime,Any option to swap the memory without eeprom settings?
Good morning,I have a problem sharing a variable between bootloader and application into my STM32F303ret6 uC. I need to write a shared variable to tell the bootloader that it has to wait for new firmware.I read many posts which suggest to declare a v...
Hello,I use a Nucleo-STM32G0B1 (512KB Flash).I would like to flash same data in fast mode, but the HAL_FLASH_Program() function ending with error. The HAL_FLASH_GetError() = 0x2A0 (PGSERR and PGAERR).Before writing I erase some flash pages.If I clean...
I want to store some data into flash (read/write)..i have no idea wheter it can be done with Nucleo L433RC-P DK. if possible plz share the example codei tried with an example code (github - controllerstech F1, F4, H7 series) . but no use of it
I try to change the option bytes of a STM32G070R from my program. i think I did everything a written in the doc:clear FLASH_CR_LOCK with the FLASH->KEYR sequence and wait till it is clearclear FLASH_CR_OPTLOCK with the FLASH->OPTKEYR sequence and wai...
Related to the STM32G030xx HAL driver.Many examples of the macro __HAL_FLASH_CLEAR_FLAG use multiple flag values ORed together. The comments on this macro seem to suggest that this is OK since the plural form is used on flagS ("Clear the FLASH pendin...
I am writing an external bootloader for the STM32F730Z8 - (why? I need one windows code that can run the bootloader for the STM32, or use the STM32 to reprog a connected ATF1508 for my client). I've done this before, using info in AN3155 and AN2...
Hi,I'm novice with the STM32 microcontrollers and this community.I'm trying to write to the flash memory of STM32L4R5 in 'FLASH_TYPEPROGRAM_FAST' mode of the HAL_FLASH_Program().The flash of the MCU is configured as Single Bank.Writing to the flash o...
