Hi,I am testing SBSFU in p-nucleo-wb55. when i am flashing user_app.sfb it flash successfully at slot1 (Download Area) but can not decrypt and hang at below STATE can you please help me how to resolve this issue and also tell me how to enable debug l...
Hi there. I have been using the wolfssl lib for a while on the freescale mcu mk82fn256xxx and the performance have been greate so far. Wc_generateSignature performs a signature within milliseconds. Recently I switched from freescale to STM, SMT32F437...
I have used STM32H750VB as my main controller for a Project and in that i am in need of AES Encryption to be done..With the help from our community friends i am able to integrate the AES part in my main coding..I have used the 192 bit plain text arra...
I'm trying to use EEPROM emulation API in a project. I have downloaded the expansion package. Based on AN4894 I need core and porting to be included in my project so I copied them under a new directory in Middleware and included the path. Then added ...
Hi All,I am using X-CUBE-CRYPTOLIB for AES ECB encryption/decryption on STM32H7 micro and using the F7 example code and library(libSTM32CryptographicV3.0.0_CM7_GCC_ot.a), provided in the crypto package. But the comparison of encrypted message fails w...
I have created a simple function to encrypt a message using the AES CBC flow suggested in the documentation (AES_CBC_Encrypt_Init, AES_CBC_Encrypt_Append, AES_CBC_Encrypt_Finish), and then using the same flow to decrypt (AES_CBC_Decrypt_Init, AES_CBC...
I am using bootloader to update my firmware and I am using dual bank to update code. When I working on bank 1, new code sending to bank2 after reset I am starting bank2 successfly, but I want to use Read Out Projection in my MCU.If I use Read Out Pr...
We have two microcontroller, one is the STM32H7 and another one without hardware CRC (need to be software CRC through an algorithm).I use SPI communication with this hardware CRC32 and I would like to know the software algorithm able to have the same...
I'm trying to enable the OB_RDP_Level_1 for a STM32L151CC but It fails. The MCU becomes bricked. I can't even boot to DFU. I need to first start ST link utility and set read out protection level 0, and then do a chip erase. But I noticed that bit OPT...
We have an STM32F37II device in an older generation of a product that ECCkeygen() works as expected. But in a new version of the product, which uses the same MCU and cyrpto libraries, and which uses nearly identical firmware (it was ported from the ...
