I complie STM32F769I-Discovery 2_Images. the final SBSFU_UserApp image's size is 532kb, It's size will increase to 131,669 kb if ITCM used. I add below code to UserApp.sct ;ITCM 16k ITCMRAM_region 0x00000200 0x00004000 { fw_update_app.o (+RO...
Hello,How can I add STM32CryptographicV4.0.1 in the STM32CubeExpansion_SBSFU_V2.6.1 middleware for SBSFU application ?The current STM32CubeExpansion_SBSFU_V2.6.1 is used libSTM32CryptographicV3.1.1_STM32H7_GCC ST crypto library for STM32H7 boards. I ...
Hi,I want to test RSA signing and verification on the STM32. I found STM32CubeExpansion_Crypto_V4.0.1 with some RSA signing and verification example for NUCLEO-H743ZI. I want to port this application for NUCLEO-H7A3ZI.How can I port the application f...
I'm using SBSFU v2.6.2 on a Windows 10 x64 machine with CubeIDE v1.11.0I was recently modifying the postbuild script in an SBSFU-based project and noticed it has a bug setting the PATH variable when looking for prepareimage executable:export PATH=$ba...
I'm using an STM32L4A6ZG (as a nucleo board). This is the code I am using:#include "err_codes.h" #include "sk.h" #include "aes_common.h" #include "aes_cbc.h" #define AES_BLOCK 16 #define IV_LENGTH 16 #define SIZE 32__ALIGN_BEGIN static const uint8_t ...
Hi support team,i am testing the sbsfu code in P-NUCLEO-WB55 but i missed out to disable security ips SECBOOT_DISABLE_SECURITY_IPS and flash into the board it set RDP level to 1 also set SFU_WRP_PROTECT_ENABLE, SFU_TAMPER_PROTECT_ENABLE,SFU_DAP_PROTE...
Hi,I forgot to comment the protections set in app_sfu.h and tried debugging the code. Later I realized and commented everything and it is not allowing me to flash the program on the device. I made RDP level 0 from cube programmer, but still write pro...
Hi,I am trying to use the STM32Cryptography library to verify the signature of a flash segment, using RSA Encryption and 3072 bit length keys.The signature is generated by a python script and appended to the hex file. The signature has a length of 38...
I could not get wanted result by using STM32F7 calculation unit. The code I borrowed for comparison was from WireShark CRC32 function. It was a table based function for speed. And I compared the STM32 CRC result with bitwise algorithm. I found out th...
