There are some older posts on the net about how to achieve a reboot in DFU mode but none of them worked for me. So I want to share my solution on how to add this functionality to your embedded firmware. First off all, I am using CUBEIDE with a STM32F...

I'm trying to write the option byte in my STM32G030 uC to be able to start the internal boot loader by pulling BOOT0 high (set nBOOT0_SEL = 0). The problem is I'm getting a WRPERR while writing. All other related registers are in default state. If I ...

Hey there. I am developing an application which uses the PSSI interface of the STM32H730. But while debugging the registers are not available in the SFR view. Any ideas?

Hey there,it's no big deal, but rather annoying. If I select one UART to be Half-Duplex the RX pin disappears from the pinout even if I select receive only. It doen't matter if I select RX only or TX only, the RX-pin won't show up again. The generate...

Maybe the memory get's wiped on reboot? Try to set a break point at ResetHandler: and step through it with the debugger. I could also imagine some kind of access violation or whatsoever so that the controller reboots again. But I haven't worked with ...

Okay, thanks for the hint. This is not very good documented. The solution seems to be: FLASH_OBProgramInitTypeDef user_bytes; HAL_FLASHEx_OBGetConfig(&user_bytes); user_bytes.USERConfig &= ~(0x1 << 24); HAL_FLASH_Unlock(); HA...

Thanks for your quick reply. If i do a grep -ri PSSI_CFGin the respective folder it doesn't return anything so it seems to me the interface registers are missing from all svd files.
