Posted on December 06, 2017 at 21:27Hi there,i have a STM32L063 and i wanna encrypt a 32-byte packet by AES-CBC.I have tested it with using the 'HAL_CRYP_AESCBC_Encrypt' and 'HAL_CRYP_AESCBC_Decrypt' and it worked everytime the same encrypted packet...
Posted on May 11, 2017 at 17:47Recently PolarSSL library has been replaced by mbedtls in STCube Third Party libraries.PolarSSL used to have STM32 specific code for some of the Polar SSL APIs. Now, in the latest STCubembedtls library does not have ST...
Posted on November 24, 2017 at 15:08I have a simple project that toogle a LED. I try to add software protection to it.Basically, it does :main(){ Init_GPIO_for_LED(); LED_ON(); while(i++ < 10000000) {}; // yes, ugly LED_OFF(); while(1) {} //...
Posted on November 22, 2017 at 14:23Hello all,Our product is being programmed on test bench and after that it is locked setting the readout protection to level 2 (RDP level 2).My question is - is it normal for this process to take about 3 minutes?Ar...
Posted on October 23, 2017 at 10:41Hi,I'm using X-CUBE-CRYPTOLIB 3.1.0.All RSA_PKCS1v15_* functions uses a 'membuf_stt *P_pMemBuf)' parameter.The documentation says : 'The structure pointed by P_pMemBuf must be properly initialized.'In the examples ...
Posted on October 19, 2017 at 11:21Hello,I am using the STM crypto library X-CUBE-CRYPTOLIB (there are several libraries and I could not find out which one was recommended so I picked the most recent one) with an STM32F417.I can't find any informati...
Posted on October 02, 2017 at 17:36My current project involves some pretty complicated logic, required for firmware update over the air. So I ended up with solution, which contains bootloader and application code, compiled separately. My current mem...
Posted on September 23, 2017 at 14:10Hello,rm0433 rev 3 and stm32h742xx.h header are not consistant about CRCDATARx.From the description in rm0433 3.3.6, is seem that there are CRDATAR1 and CRCDATAR2.rm0433 3.5 only lists CRCDATAR at offset 0x5c and...
Posted on September 21, 2017 at 13:03Hello All,I am using STM32F767ZI Nucleo Board. I am getting DCRCFAIL in data transfer using CMD53 in SDIO.Any possible reason for CRC failure? Could there be any relation to clock out from SDMMC adapter?I am able...
Posted on March 24, 2016 at 14:16Hi, I cannot manage to enable the RNG that is on my STM32F407VG. Using https://github.com/libopencm3/libopencm3-examples/blob/master/examples/stm32/f4/stm32f4-discovery/random/random.c, setting the RNGEN bit in RNG_C...
