I need to perform SFI on an STM32U599 MCU, so following the wiki article "SFI Step-by-step on STM32 boards" I prepared the firmware and programmed the HSM V2 smartcard.I'm sending the commandSTM32_Programmer_CLI -vb 1 -c port=SWD mode=HOTPLUG -sfi xx...

I'm using an area of Flash in an STM32U5 to store some information that I need to retrieve connecting the board to the SWD port. Data is sent out using the ITM port. All is working as expected connecting the board using the STM32 Cube Programmer, all...

I have problems in getting this working. I moved from FreeRTOS to Azure RTOS, and I found out that in general there's lot less information on this RTOS. So I've been looking into the few resources, but I'm afraid I'm missing some important points. Ar...

Hi @Jocelyn RICARD , thank you for your explanation. I start working on this solution then, maybe we'll switch to the STM32U5A9 in the future to have crypto hardware acceleration.Just a note: in case of STM32U599 in file User/stm32u5xx_hal_msp.c the ...

I've been reading a lot and found out that SBSFU might be the solution I'm looking for. I then looked at the example in the STM32CubeU5 firmware, and I couldn't adapt it to the STM32U599 (not the required encrypt/decrypt module). Is there a way to ad...

Hi @Jocelyn RICARD , thank you for the explanation.Yes, both RDP1 and RDP2 regressions are password protected with OEM keys so the MCU can be rewritten with the new firmware. So what would be the best way to perform a firmware update? I thought about...

Thank you, @Jocelyn RICARD .As I'm new to the mechanism, is there any guide I can follow to do what you suggest? My application doesn't use TrustZone, I would just need to enable RDP2 and leave a chance to update firmware thru SWD if necessary, apply...
