感觉应该可以可以添加一些自己的其他信息。先做个标记吧，后面再来学

µVISION: CRC Example

Question
My project requires a checksum or cyclic redundancy check (CRC). How is this done in MDK-ARM? How is the checksum added to the final image?
Answer
Application Note 277: ROM Self-Test in MDK-ARM shows one approach using MDK and SRecord to perform startup and periodic testing of ROM. The user can experiment using different CRC32 routines (source code provided). The application note contains two example projects for a simulated device. In this approach, SRecord modifies a hex file to include the checksum at a specific address, before µVision programs the device.
