–Input_Data = 0xC1 –POLY = 0xCB –Initial_Crc = 0xFF All STM32 devices implement a CRC peripheral as described in Section 1.1. The CRC calculation unit has a single 32-bit read/write data register (CRC_DR). It is used to input new data (write access) and hold the result of th...

The CRC calculation unit has a single 32-bit read/write data register (CRC_DR). It is used to input new data (write access) and hold the result of the previous CRC calculation (read access). Each write operation to the data register creates a combination of the previous CRC value (stor...
The calculation apparatus uses 8 rows of shifting links with the inputs of each row coupled to the data outputs of the preceding row. Each shifting link shifts its input bit one bit position toward the most significant bit, and selected shifting links perform an exclusive-OR operation between ...

ielftool.exe工具跟CRC相关的一共两个参数选项,一是--fill用于填充,二是--checksum用于设置算法,具体参数使用细节详见 \IAR Systems\Embedded Workbench 8.50.6\arm\doc\EWARM_DevelopmentGuide.ENU手册里的Checksum calculation for verifying image integrity小节。
This CRC calculation unit is very efficient. However, it is not only dedicated to check the integrity of the flash memory contents. Which means that, it could be used to verify the integrity of other memories. The CRC also needs other resources ...
