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...
Posted on December 15, 2013 at 21:04Hi, After a few days of experimenting and struggeling my SPI application CRC check somehow still does not seem to work. I'm using the STM32F103ZD uC. Master SPI1 sends data and slave SPI2 receives this data. MOSI/...
Posted on January 15, 2013 at 15:42Hi, I use STM32F107. I have to generate a random number. I don't see how to do it :\ Anybody for help ? #random-number #rng
Posted on November 22, 2013 at 17:25I'm having trouble bridging the two pools of information I read on the subject of TLS handshakes and the AES cryptographic processor. TLS is an exchange of a server certificate, a client premaster secret, and a pu...
Posted on November 12, 2013 at 22:51I would like to use the hardware CRC on the STM32F407 with DMA. However, my data comes in Big Endian, so if I just use the memory to memory DMA setup my CRC does not compute correctly. Is there a way that I can co...
Posted on October 11, 2013 at 12:38Hi all ,Currently i am trying to communicate with Vending machine through DEX protocol via STM32.But i could not calculate accurate CRC-16 byte so i receive always an error.There are many online calculator about cr...
Posted on October 07, 2013 at 15:33Couldn't find topic related appnotes ... Is there any? Like Atmel's http://www.atmel.com/Images/doc2589.pdf There has to be a way to make a easy and protected firmware upgrade on STM chips! Or I'm just bad at findi...
