How to use the MDK compiler to add firmware version information in the STM32 program HEX file

This article introduces a small trick: Use the MDK compiler to add firmware version information in the STM32 program HEX file. Code code show as below: / / -------------------------------------------------------------------------------------------- ------------------------------ # include "absacc.h" / / -------------------------------------------------------------------------------------------- ------------------------------ # define verinfo_addr_base (0x8009f00) // version information in the storage address in Flash Const Char Hardware_VER [ ] __ATTRIBUTE __((VERINFO_ADDR_BASE + 0x00))) = "Hardware: 1.0.0"; const char number_ver [] __ATTRIBUTE __((AT (Verinfo_addr_base + 0x20)) = "Firmware: 1.0.0"; const char compiler_date [ ] __ATTRIBUTE __((Verinfo_ADDR_Base + 0x40))))) = "Date:" __date __; const char compiler_time [] __ATtribute __((at (verinfo_addr_base + 0x60))) = "Time:" __time__; / / -------------------------------------------------------------------------------------------- ------------------------------ Write into the program: Option configuration: Flash address and size don't make any modifications! HEX file: Serial print output: Disadvantages of the above method The above operation is feasible, but there is a disadvantage that the generated bin file is full of Flash size, resulting in a full flash reading and writing. In fact, this can put the storage address in front, such as a place to be offset, and do not have to change the designated address. According to the above operation, the program is at the end to the verinfo_addr_base address This will be filled into 0x00. Modify VERINFO_ADDR_BASE to reduce the address, or to force the specified address, automatically assign by the compiler, but then look for the corresponding version identity string. Optimization If you don't want to fill 0x00 in the previous paragraph, let the HEX file size is small, you can change the size of the flash in the option configuration, set verinfo_addr_base to start from the space behind FlashSize, so that the generated HEX file is small, and Unused space will not be populated with a lot of 0x00.
