Posted on March 08, 2013 at 10:31 I've stolen some code from Clive's post here <https://my.st.com/a99fbbe2> (Thanks Clive!) and it works great for computing a CRC all at once. In other words, the following function signature. unsigned...
Posted on June 15, 2016 at 19:16I just discovered the hard way that if you initiate a full flash erase cycle (in my case, by going from RDP level 1 to level 0) and reset the chip before that process is complete then the chip is essentially (AFAICT) ...
Posted on April 10, 2016 at 09:13Hi allI'm setting the read out protection to level 1 , in the beginning of my main() fxnAfter setting RDP I generate system reset using HAL_NVIC_SystemReset() fxnAfter the reset I'd expect the RDP to be set to level ...
Posted on March 26, 2016 at 08:11Good afternoon. Calculate checksum CRC32 of ROM in embedded program is very simple. But how to calculate and write it in image of ROM on stage building? It possible in Ac6 System Workbench without external tools? Tha...
Posted on March 18, 2016 at 10:54There is a crypto library offered for download from ST official site here: http://www.st.com/web/catalog/tools/FM147/CL1794/SC961/SS1743/LN1920/PF262570However when I try to get the library the link just drops me to ...
Posted on March 14, 2016 at 18:01I'm using the CRC unit on the STM32L486. In the reference manual it states that:''CRC computation is done on the whole 32-bit dataword or byte by byte depending on the format of the data being written.''However, late...
Posted on March 01, 2016 at 13:39Hi, My problem is this, i have a product that have in the pages 0-3 a bootloader, and the RDP is state ON to protect my code, then the application code (120KB). All works fine and with this bootloader i can change th...
Posted on February 16, 2016 at 16:01 Hi! I'm using the X-CUBE-CRYPTOLIB (AES-256-ECB) on the STM3220 devboard using System Workbench (GCC) with no luck. I set the config.h file (tried every permutation nearly), my project compiles success...
Posted on January 05, 2016 at 08:15Just noticed this library called X-Cube-Cryptolib. Quick question is , if i use the HW accelerated version of the lib, is it safe to make calls to the library from different RTOS threads considering they will be ca...
Posted on November 11, 2015 at 18:11I'm trying to install the STM32Cube Cryptographic Library v3.0.0 on a fresh STM32CubMX install, version 4.11.0, under Windows 7. Installation fails with a message that ''This Package version is not managed on this...
