Hi @ communityI am working around the flash lock protection that was somehow enabled in my development board(B-U585-IOT2A) while testing the TF-M SBSFU Application and now i am unable to do a flash erase on my chip. The cube programmer is showing the...
Hi all,I would like to know what are the known issues for the cryptographic library (version 4.0.1). How I can do ?Thanks,Damien
Hi,Can anyone help me why size of rom area using large size?I'm porting SBSFU STM32G071 to STM32G0B1 to add USB CDC. Best regards,TDR
After using STMCubeProgrammer 2.21 to set the RDP byte to BB, the board works fine, but Cube programmer is later unable to access the board; I've tried different modes, under reset etc. The disk folder shows when plugged in to the USB with FAIL.txt...
Hi all,I'm working in a project (with STM32L462) in which we're building our own bootloader to perform secure boot and firmware upgrade. There are some issues we're still struggling with, regarding protection of our code (and data). Hopefully someon...
I set up a very simple test project. It is a .ioc file from another project to which I wanted to add a virtual com port interface. I added the vcp in the cube plugin and generated the code. However, if I include a CDC_Receive_FS() function this gets ...
Hi @ST Community GreetingsI'm trying the TF-M Application package v1.2 released by ST and am following the instructions in UM2851.I'm currently in the step shown below:in windows im unable to run the TFM_Update.sh script that is provided in the follo...
Hello all, When I had a beautiful STM32U5 in hand the world was still good.But now I have a comprehension question about the STM32L0, I have an 8-bit buffer and now the fastest way to AES decrypt/encrypt this data is via DMA with active burst mode. T...
Hi,We are migrating our code from using the legacy crypto lib to the libSTM32Cryptographic_CM4.a.I can not find api document describing the functions etc, is there any thing like there was for the legacy lib (like https://www.st.com/resource/en/user_...
My controller is STM32L462. I need to compute CRC16 for Modbus application. There is CRC initialization function:void MX_CRC_Init_CRC16(void) { hcrc.Instance = CRC; hcrc.Init.DefaultPolynomialUse = DEFAULT_POLYNOMIAL_DISABLE; hcrc.Init.DefaultI...
