Hello,I’m working with the STM32H735, and I need to enter bootloader mode to program the microcontroller. I modify the SYSCFG->UR2 register to set the address to 0x1FF00000, then perform a software reset. I use this method because I have no control o...

Hello everyone,I am experiencing an issue with my stm32H735 microcontroller after enabling RDP level 1. The program that was working perfectly (blinking led) under RDP level 0 no longer executes after I changed the protection level to 1.What I have T...

Hello,I found a solution to modify the RDP level from a function that runs directly from SRAM. This approach is necessary because I do not have control over the BOOT0 and NRST pins (BOOT0 is tied to 0V, and NRST is connected to 3.3V), which means I c...

the STM32H735 I’m using has a single flash bank, so I can’t load firmware to a separate bank

In my current project, the only way to enter bootloader mode is to change the next boot address via the SYSCFG->UR2 register by setting it to 0x1FF00000U, followed by a software reset. This means I can only enter bootloader mode from software located...

I corrected the title, I'm talking about Level 1

Apologies for the confusion. I made a mistake in the title. It should have read "Issue with STM32H735 Bootloader in RDP Level 1 (0xBB) Mode" instead of "Issue with STM32H735 Bootloader in RDP Level 2 (0xBB) Mode."
