SBSFU USB Local Loader STM32F4xx
Hi i was wondering how i should go about implementing USB instead of UART to download the firmware in the SBSFU bootloader. I have successfully managed use USB in DFU mode to install a new firmware.

Debugging bootloader + app: How to get a CRC header to the target, too?
I have a workspace in CubeIDE that has two STM32F0 projects: A bootloader and an app.To be able to debug both, bootloader, and then jumping through to the app code, I made an additional Debug Configuration where I added the source folder, and the sym...
Problem with self programming after enabling read out protection
HiI've implemented a bootloader that receives, cache and upgrades my main program.When RDP (read out protection) is not enabled everything works as expected with no problem.If I enable RDP. And if I upload the same program as the one already on the c...
Installing Java - I think I may need a commercial licence. Or so ST provide one?
When I run the STM32SecuWS-material.exe installer, it tells me I need to install Java and takes me to Oracle's website. But my understanding is that Oracle Java is not free for commercial use and we would be using STMicro security in a commercial env...
Test F7 SPI CRC Generation
Hello,i have a programm which is sending 2bytes + 16bit CRC from SPI2.There are two STM32F765 on my board. The test programm is generated with CubeIDE and only SPI2 initiallyzed.One MCU is calculating the crc correct and the other is not correct.(Che...

Enabling SBSFU security flags cripples my code
I've ported the SBSFU package for my user app. It works great when only read out protection is enabled. Everything works as it supposed to. However, when I activate other security flags random errors/problems arise in the code. For example, when I ac...
How to Debug Code Executing from OctoSPI / OTFDEC in Keil MDK?
Hi guys,I'm currently utilising SBSFU as an external flash secure bootloader (with all security settings turned off for debug) using the STM32H7B3's OTFDEC (On-the-fly Decryption) peripheral.My user application boots and runs via the OFTDEC and memor...
What is de CRC16 used on SPI peripheral? the Polynomial is configurable, but the init value and reverse or not, is not documented.
I have a SPI on STM32F746 configured:/* SPI6 init function */void MX_SPI6_Init(void){ hspi6.Instance = SPI6; hspi6.Init.Mode = SPI_MODE_MASTER; hspi6.Init.Direction = SPI_DIRECTION_2LINES; hspi6.Init.DataSize = SPI_DATASIZE_16BIT; hspi6.Init.CLKPolar...
