How to compile bin file for LPC 1343 with checksum?

Question

Programming

After flashing through the built-in bootloader, the program does not start (it is flashed by copying the bin file into a microcircuit, which is defined as removable media in the computer). On the Internet, I found out that the built-in loader checks the checksum that should be in the bin file, and if everything is in order, then the main program starts. The CooCox IDE I'm working with doesn't write the checksum to the file when it compiles. Has anyone experienced something similar, please?
