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...
Obviously Read Protection Level 2 is the most secure in protecting IP on the G series MCUs, but in the worst case scenario it could involve unsoldering and replacing the IC. Do you use Level 2 or is Level 1 secure enough for most scenarios ?
I have to generate CRC on MCU (STM32L476VG). I am using code as below for generating CRC.uint32_t HAL_CRC_Calculate(CRC_HandleTypeDef *hcrc, uint32_t pBuffer[], uint32_t BufferLength) { uint32_t temp = 0U; /* CRC output (read from hcrc->Instanc...
Hi,I want to block flash memory for writng after programming it. It is important that write protect should not be possible to deassert. I have read about RDP mechanism, but there is information that on level 2 write protection is permament, but only ...
