Hi, I want to port SBSFU to my project which was written for the STM32F756VGT microcontroller by Keil.So I have some questions regarding this situation.At first, I took the `STM32F769I-Discovery` example of SBSFU as a base project that I need to make...
What .c file has the code for the YMODEM portion of the SBSFU pictured below ?I have found the string "File> Transfer> YMODEM> Send" a few times, but when I changed the string to test if I found the correct area, nothing changes in the picture above....
Is there a way to support X09 certs for Secure Boot and Secure Firmware Authentication (SBSFU) features on STM32 MCU's? All the examples I've seen on this use bare public keys rather than certificates. Thanks!
Hi, I am implementing ECDSA signing functionality based on some sample code in the package en.STM32CubeExpansion_Crypto_v4.0.1. I am getting the following linker error. What am I missing? Thanks! c:\st\stm32cubeide_1.6.1\stm32cubeide\plugins\com.st.s...
I'm trying to add a authentication mechanism with a symmetric key stored in the system memory but I'm not sure if it's the right way and i also don't know how to store this key in the system memory.I read about SBSFU but not sure about it.Kindly advi...
If not, what is the TPC used for?
I'm using YMODEM in TeraTerm to transfer my internal and external firmware and my goal is to make this a single file. I have already combined the two files into a .bin and when I transfer them via YMODEM, the transfer stops once it reaches the end of...
MCU : STM32F415I enable readout protection successfully (customer requirement). Then in case of a new software update, I jump to the UART bootloader from my code. However, when in the bootloader I need to disable RDP. When I send RDP disable command ...
Hello everyoneSo I've managed to adapt and build my custom user app. Flashed it into the device.But it fails on startup somewhere between gpio and timers initializations in main().Console shows the following text:= [TEST] write 8 bytes @ Isolated cod...
Hello guys,I've implemented SBSFU along side with an USB standalone loader for my project using a STM32WB. My question is, should i implement hardware semaphores and shci_notification for CPU2 during flash erasing and writing operations on my USB ext...
