Posted on December 19, 2014 at 11:27We would like to enable level 1 read-out protection from code running on an STM32F437. We have code that will enable the protection using the following steps:1. Unlock OPTCR by writing twice to FLAS->OPTKEYR, usin...
Posted on November 21, 2016 at 18:10Looking to see if someone can shed some additional light on programming the memory read protection level 1 or 2 for a STM32F030 device. There are a few examples but they perform other options that are not required...
Posted on August 17, 2016 at 12:34 Hi, I'm implementing the read out protection for the F746 controller. Changing it from level0 to level1 at the first start from my code. First I realised that the level1 was setted but not saved after a...
Posted on June 15, 2016 at 19:16I just discovered the hard way that if you initiate a full flash erase cycle (in my case, by going from RDP level 1 to level 0) and reset the chip before that process is complete then the chip is essentially (AFAICT) ...
Posted on April 10, 2016 at 09:13Hi allI'm setting the read out protection to level 1 , in the beginning of my main() fxnAfter setting RDP I generate system reset using HAL_NVIC_SystemReset() fxnAfter the reset I'd expect the RDP to be set to level ...
Posted on March 01, 2016 at 13:39Hi, My problem is this, i have a product that have in the pages 0-3 a bootloader, and the RDP is state ON to protect my code, then the application code (120KB). All works fine and with this bootloader i can change th...
Posted on October 06, 2015 at 12:24Hi all, Anyone knows why the following code is not disabling the flash memory readout protection? It is being executed on a STM32F103 microcontroller.FLASH_Unlock(); FLASH_ReadOutProtection(DISABLE); FLASH_UserOp...
Posted on March 19, 2015 at 17:16I am wondering if this was expected. I use the DFU-USB image to jump to an app on 0x800c000, but before jumping it sets the RDP/CRP level to 1 within it's main(). Then I use the Dfuse demo app to flash a new image o...
Posted on October 16, 2014 at 17:32Hi all,I have a very strange issue with STM32F407ZG; sometimesthe RDP level 1 is automatically set and then using STLink Utilities I can goback to RDP level 0.BUT, Now I get RDP level 1 SET and I can't go toRDP lev...
Posted on December 17, 2014 at 02:50In my stm32f405 level 1 is active.I can't updata mcu flash.I need change RDP to level 0 to reprogram. Anyone can help me? thanks. #stm32f4-rdp
