Resolved! A problem in Building SBSFU projects
I went through the MOOC part 6 and I thought of creating a new project for Nucleo -L476RG (from the scratch), I Created a new code using CubeMX (Use same pins ands USART) and followed the same steps as video 2,4 as describes. but once I use FLASH_SBS...
Resolved! Cryptographic Library VFP support on STM32F7
Currently working on a Bitcoin hardware wallet on the STM32F7 Discovery platform. I wanted to use the cryptographic library to secure information stored in the EEPROM as well as perform hashing functions. VFP is not supported in libSTM32Cryptographic...
Resolved! How to use BOOT0 in SBSFU?
Hi all, I am porting the SBSFU to the custom STM board which is running in the Stm32L476JGYx. Normally user button is connected to the PC13 in the Nucleo board and in my custom PCB I made the user button for the Boot0 (PD7) I use this only for the bo...
STM32F439ZI, the HASH_Start_DMA() function works as expected if the size parameter is 16, elsewhere it doesn't calculate anything
I'm trying to use the STM32F439ZI HASH accelerator with the following code:#define INPUT_SIZE 16 static uint8_t hash_test_buffer[224] = {0}; static uint8_t hash_test_output[224]; HASH_Start_DMA(&hhash, hash_test_buffer, INPUT_SIZE, HASH_ALGOSEL...
Cryptolib RSA Nucleo-L476RG working slow
Hello to all!Using X-Cube-Cryptolib for RSA algorythm on Nucleo-L476RG board, encryption and subsequent decryption of demo message going very slow - 2 seconds, its mostly decription, i using hardware timer2 for time measuring.Is there any ways to re...
Is it possible to read STM32L0 with RDP L1 using another STM32L4 without RDP?
I have one STM32L4 that act as master MCU.This master MCU is set with RDP L0. I have another slave STM32L0 with RDP L1. I tried to read this STM32L0 using this master MCU but did not get any result. It seems like this slave MCU did not run the code c...
