I am confused about the setting of the SPI CRC functionality: it is not clear what CRCSIZE is doing and how to set it. I understand that to get a N bits CRC you have to choose a N+1 bits polynom, but why is the length of the CRC not deduced from the ...

When loading a table (for CRC16-CCITT) in the RAM on the STM32F303, element 204 (value: 0x18c0) is corrupted. The value on load is 0x18c1.To test, I hooked up the openocd debugger, attached a breakpoint to the return statement and read out the conten...
In the code it says the following:/** * @brief This function writes a data buffer in flash (data are 32-bit aligned). * @note After writing data buffer, the flash content is checked. * @param pFlashStatus: FLASH_StatusTypeDef * @param pD...
I started a new project, and my security requirement states that user authentication is required when updating firmware.I wonder if there's a feature for this, and if not, can the bootload side be modified to meet this requirement?I searched and foun...
IAR would fill unused flash and optionally append a crc to aid with the integrity check some of us need to do for regulatory compliance But since IAR's been replaced what provisions are in Atollic to fill unused flash and optionally append a crc? Is ...
I wants to encrypt 8bits of data using AES256 Security with STM32L442KC . And sending Encrypted data through UART. I am confused in code that code is correct or not....please let me know any correction in this code. I am using Atolic true studio.u...
Need to protect data access through j-tag, but need to program flash through inbuilt boot loader
