Posted on October 28, 2014 at 17:38I want to calculate a CRC over the whole Flash Memory (16kB) of a STM32F030F4. I works fine up 8kB. Putting Values >8192 for BufferLength into CRC_CalcBlockCRC(uint32_t pBuffer[], uint32_t BufferLength). The progra...
Posted on October 24, 2014 at 23:18I want to use the CRC example of IAR ''ROM size save with CRC32 Note 52791'' from my Boot.The problem is that the intvec area set on start of the APP ROM but don't get into the CRC calculation.Today I see that the ...
Posted on October 20, 2014 at 13:51I want to make a CRC check over the APP FLASH area (I use a BIN file) to know that my APP update O.K.For that I have some question.1. Does the IAR has an option of giving me the CRC of he BIN file I made ?2. How c...
Posted on October 14, 2014 at 17:39I am trying to figure out a way to secure a small section of user data on the STM32F437, and keep it in place during reflashing the device. I ideally want to be able to make it so this data is read protected, but t...
Posted on July 02, 2014 at 08:54Hello, I have tried ECC_KeyGeneration_SignatureVerification example in STM32-CRYP-LIB with STM32 F407 (toolchain is IAR) But, when ''Generate ECC key pair'' be executed, the status be changed to FAILED (value:6002 RNG...
Posted on June 04, 2012 at 02:59Hi: From simpleMAC & datasheet, it mentioned the STM32W has AES encryption h/w module & API. But how about AES decryption? It takes long time to fulfill this function in software. And i think it is quit strange...
Posted on March 25, 2014 at 18:00Dear All, I run into troubles when I try to start up the crypto processor of my STM32F215. After the line 1, the cryptoprocessor peripheral does not start up: line 1: RCC_AHB2PeriphClockCmd(RCC_AHB2Periph_CRYP, ENABL...
Posted on February 10, 2014 at 17:32Hello,I'm currently implementing AES CMAC crypto using the STM32 crypto library from ST and I'm unable to get the example code to work without returning an error. I'm using an STM32F103.The example encrypt routin...
Posted on February 26, 2014 at 17:46 Hi! I'm coding for a IAP program using standard procedures as follows: //normal startup JumpAddress = *(__IO uint32_t*) (ApplicationAddress + 4); Jump_To_Application = (pFunction) JumpAddress; __s...
Posted on January 31, 2014 at 23:17I have a question about the HW crypto acceleration in the STM32F4 family. According to Note 2 on p.12 in the STM document ''STM32 Cryptographic Library Package Presentation'' (see here: http://www.st.com/st-web-ui...
