Is this the right way? if (FLASH_OB_GetRDP() != OB_RDP_LEVEL_2) { HAL_FLASH_Unlock(); // Unlock the flash memory HAL_FLASH_OB_Unlock(); // Unlock the option bytes *(__IO uint8_t*) OPTCR_BYTE1_ADDRESS = OB_RDP_LEVEL_2; // Set RDP2 HAL_FL...
Hello, My project is based on the STM32H753 chip.I Using the STM32CubeProgrammer and try to set the RDP level from 0 to 1, I get the error "Error: Expected value for Option Byte "RDP": 0xBB, found: 0xAA".I only enable the Secure Protection.How can I ...
Dear community,where can I find the source code for this generated MX66UW1G45G_STM32H7S78-DK_XSPIM1-SFIx.stldr file?I need to load binary files on an sd/emmc flash passing through the OEMiRoT boot that loads the specific external loader I want to imp...
Hi,I want to add a function in the code to update the option bytes and set the read protection to level 1. However, this version sometimes bricks the MCU (STM32G030K8) after flashing, making it unable to connect with the J-Link.Q1: Why am I unable t...
Hello everyone,I'm experimenting PCROP activation on stm32h743 following this ST-tutorial: https://youtu.be/7Wr90XFA8_Q?si=tDpqUtMdin9Oyn-PThe activation works fine but i cannot disable PCROP using CubeProgrammer.I did a RDP1 to RDP0 regression with ...
I have STM32U5 MCU and the TrusZone is disabled. Is it possible to have secure boot or not. If yes, please can you explain to me how I can achieve this. Thanks a lot0 Kudos Reply
Hello .According to the reference manual, the default RDP level is set to level 1. However, after performing a full erase with ST-Link and then writing the hex file, the RDP level was found to be set to 0.I would like to set the RDP level to 1 at the...
Hello,please I need a confirmation about RDP level2 and WRP combination on stm32g031 chip.Based on RM0444.Rev5 Table 19, if I use my own bootloader and I write-protect the flash sectors, I have to avoid activating RDP level2 or I'll loose the opportu...
Hi,The STM32U5 has a password feature to restrict RDP regression from level 1 to level 0. However it seems that STM32CubeProgrammer CLI is unable to activate this via the USB interface of the built-in bootloader. If I do it via STLink then it works f...
Hello, I am using STM32F103c6 cortex-m3. I am using 100 micro controllers in various boards. In some around 10 micro controllers, I have seen a issue of option bytes getting corrupted. Even though I am writing 0xA5 to RDP to remove read protection wh...
