I want to apply Read Protection to the STM32L552CCT6 .If you execute HAL_FLASH_OB_Launch(); after setting Read Protection, reboot does not work.Read Protection is applied only when the power is physically rebooted.I want Read Protection to be appli...
HiI've implemented a bootloader that receives, cache and upgrades my main program.When RDP (read out protection) is not enabled everything works as expected with no problem.If I enable RDP. And if I upload the same program as the one already on the c...
I protected the flash from code running on the MCU using HAL, but while trying to unprotect it using STM32CubeProgrammer the board could not be unprotected ("Expected value for Option Byte "RDP": 0xAA, found: 0xBB") and became unresponsive. After thi...
I'm trying to set the Read projection level to 1 after programming the application. Our manufacturing setup requires that we use J-Link rather than the ST-Link. I tried making a set of exit steps for the J-Link but it isn't working; I'm wondering i...
Dear,I am setting RDP to level 1 in my application, After setting it I call System reset HAL_NVIC_SystemReset(); After reset I am expecting the MCU is locked, but it seems I read in code the MCU is still in level 0 so the procedure of setting RDP to ...
Is it possible to set level 2 RDP to just a subset of a certain Flash bank? not the entire bank. (Begin Address -> End Address for example)Is it possible to set RDP levels for an external flash not the internal MCU flash?
I am trying to setup the RDP programmatically on the STM32H7. I am running the code below. All functions return HAL_OK except HAL_FLASH_OB_Launch() which returns HAL_ERROR and its unclear to me why. Any ideas on how to debug this will be helpful as w...
I am using STM32F207. The project that im working on will later on will be used by a bootloader. I am, therefore, trying to add crc information in the hex file so that bootloader will be able to validate its correctness.I am using srec_cat to calcula...
I have a project based on an Stm32F767. If I load the hex file and then manually enable readout protection to level 1 with the STLinkV2 utility, the board fails to begin to execute code after reset. Why? What is the correct way to use this feature?
