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 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 23, 2015 at 17:51 I am starting using the crypto library and with a STM32F407 device I don't have the hw hash peripheral and I must use the software library My version: M4_CryptoFW_RngHW_2_0_6.a My code ...
Posted on January 04, 2015 at 21:24hi every oneas you know there are many crypto libs with supporting from crypto algouritms like: AES,DES,3DES &...such as wolfssl,cyassl,cyclone ssl,stm crypto lib(for stm devices ) & ...my question is whats differe...
