Stm32 write to flash Nov 8, 2024 · If you decided on a STM32 flash memory HAL approach, here’s the basics on how to program your microcontroller easily. So you should change FLASH_SECTOR_10 to FLASH_SECTOR_11. Jul 17, 2023 · 3. You can For STM32 Flash operations, we’ll use the HAL FLASH APIs that can be categorized as follows: Lock and Unlock the FLASH interface; Flash Erase Functions: Erase page, erase all pages; Flash Program Functions: half-word, word, and double-word; STM32 HAL FLASH Write. . The erase function is as follows: It is always better to use the last address space/pages/sector to store values since the main application starts from page/sector 0 and we don’t Jan 12, 2019 · You want to write sector 11 but your pEraseInit. Perform the data write operation at the desired memory address, inside main memory block or OTP area. Also if you are use CubeMX you can try following write and read function without init function. Only double word can be programmed. com Jun 20, 2023 · Also, before an erase and write operation is done, the flash memory needs to be unlocked using the function HAL_FLASH_Unlock() and locked using HAL_FLASH_Lock(). Sector variable is FLASH_SECTOR_10 in your init function. 4. Set the PG bit in the Flash control register (FLASH_CR). The HAL_FLASH_Program is used to write to the flash memory. FPEC (Flash memory program/erase controller): write operations to the main memory and the information block are managed by an embedded Flash program/erase controller (FPEC). Wait until the BSY bit is cleared in the FLASH_SR See full list on controllerstech. – Write a first word in an address aligned with double word – Write the second word 5. The Hardware Abstraction Layer (HAL) should be pretty simple to set up using a few examples below. IAP (in-application programming): IAP is the ability to re-program the Flash memory of a microcontroller while the user program is running. Use the HAL_FLASH_Program function to write data to the flash memory. phvcdaopwyqfgzptgamdrohtzxnjqmshdxalpihvvdbjq
