SHCI_C2_Reinit produces error code 0xFE (and an invalid HCI command complete packet)
I just updated SBSFU to version 2.4.0 (this version finally uses SHCI_C2_Reinit() to allow the application to run the regular initialization sequence even if C2 is already started by SBSFU)SBSFU 2.4.0 now always initialized C2 (independently of it ac...
System halt when using STM32CryptographicV3.0.0_CM4_KEIL_otslsm1elfspf.lib on STM32F429IGT
Hi allI used STM32CryptographicV3.0.0_CM4_KEIL_otslsm1elfspf on STM32F429 for ECC encrypt and decrypt. But after use several time library function(likes ECCinitEC, SHA256_Append, etc), the system was halted. If I used AES encrypt and decrypt functi...
Need help on STM32L562 for hash (sha256)
hello, now I am program stm32l562 for hash(sha256). I have no idea what to do. Can anybody give me some examples or ideas? Thank you very much.
Resolved! SPI DMA CRC transmit
hi,my type is stm32f031, i try to debug ' spi + dma + crc' mode. i have no idea about transmit crc .i just enable crc_en, and set the bit crc_next every sending 8bit value.my logic analyzer occured the only 8 bit datas, it not contains the the crc va...
Problem running SBSFU with Keil RTX5 (RTOS)
I am trying to adapt an existing project that uses Keil RTX5 (RTOS2) which was written in C++ to include SBSFU functionality. So far I have got the project to build. However I am not sure about the integrity of the build as Micro-lib does not support...
Resolved! Due to an overwhelming response, our capacity has been reached and, unfortunately, we are unable to confirm your registration.
Listen, I have chosen the day that had a plenty of free seats! First I have chosen another day but the system replied that this day is full, then I've chosen another one which was OK. Now I am simply thrown away from the event! WTF? Who do you think ...
Resolved! STM32G4 CRC8 with user polynomial doesn't match other method
Hello, there,I need CRC8 in my design. Thinking with the Polynomial programmability in Stm32G4 . It should be straight forward.When I tried to test with the example "CRC_UserDefinedPolynomial" coming with stm32cube_fw_g4_v130 in "Examples_LL" folder,...
Resolved! Why SBSFU code size NOT reduce by Select AES-GCM symmetric cryptographic scheme?
Hi,According to the document "AN5056-Integration guide for the X-CUBE-SBSFUSTM32Cube Expansion Package" Table 3. SBSFU code size reduction,In project "NUCLEO-G071RB", I build "1_Image_SECoreBin" by modify SECBOOT_CRYPTO_SCHEME from "SECBOOT_ECCDSA_WI...
Which encryption is best for protecting firmware ?
I am using STM32F0 , F1 , F4 series of MCU now i want to apply encryption for protecting my firmware so i want to know which encryption is best for this purpose?
