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...

Posted on November 21, 2014 at 08:06Hi,I'm experiencing strange issues with a product based on STM32F407. When doing short power outages to the PCB (uses 24VAC), it sometimes erases or corrupts flash page(s) that are used for eeprom emulation. Pages...
