Posted on October 06, 2015 at 12:24Hi all, Anyone knows why the following code is not disabling the flash memory readout protection? It is being executed on a STM32F103 microcontroller.FLASH_Unlock(); FLASH_ReadOutProtection(DISABLE); FLASH_UserOp...
Posted on November 09, 2013 at 13:03Hello Everyone,Does anybody know, how exactly to use STs crypto library (V2.0.6 for STM32F427) such that it behaves / is compatible with openssl?i.e. generating an encrypted file via:openssl enc $encryption -p -e ...
Posted on June 14, 2015 at 15:15Hi,I'm developing on the stm32f207 with the M3_CryptoFW_RngHW_2_0_6.libI would like to use the sha-1 from lib but from some reason I do not get the correct result.Here is my test...My input buffer is 8 bytes: 1,2,3,4,...
Posted on May 19, 2015 at 12:47I am trying out some examples of the crypto library from ST, but its not working the way it should.If I try the AES-CBC192 examples on a STM32F107 (STM3210C eval board),I can verify that the encrypted cipher text is co...
Posted on March 04, 2015 at 18:29Hi all, I'm using the STM32F205VBT on some boards I developed. Software development is done under Win7/x64 using Eclipse (4.4.1) with CDT (8.5.0), Toolchain is gcc 4.8.4. (arm-none-eabi). My Software Project is creat...
Posted on April 25, 2015 at 01:18Hi, I modify the spi sample code but enable CRC function, however I always get CRCERR. I dont know the reason. Here is the initialization of SPI: SPI2->CR1 |= SPI_BAUDRATEPRESCALER_256; SPI2->CR1 &= ~SPI_CR1_CPOL;...
Posted on April 08, 2015 at 13:09I'm trying to use the CRC peripheral on STM32F3 to calculate the CRC at byte-level but I can not get the same result as indicated in application note AN4187. The following snippet of code should return a CRC equal to...
Posted on March 19, 2015 at 17:16I am wondering if this was expected. I use the DFU-USB image to jump to an app on 0x800c000, but before jumping it sets the RDP/CRP level to 1 within it's main(). Then I use the Dfuse demo app to flash a new image o...
Posted on October 16, 2014 at 17:32Hi all,I have a very strange issue with STM32F407ZG; sometimesthe RDP level 1 is automatically set and then using STLink Utilities I can goback to RDP level 0.BUT, Now I get RDP level 1 SET and I can't go toRDP lev...
Posted on February 27, 2015 at 17:48Dear all,In Cube version of STM32F4, there is a strange code.In PolarSSL/SSL_Client/Src/main.c => RandVal()Is there a reason to use ''&&'' instead of ''&'' in the following line:*(output + offset) = HAL_RNG_GetRan...
