I need to generate a hex file from the axf file to use with Flash Magic. I need to have the LPC Checksum computed correctly to be detected by the bootloader.
Accordingly to this http://support.code-red-tech.com/CodeRedWiki/OutputFormats it's recommended to generate the hex file from the bin file. But as my application is designed to run from 0x8000 it doesn't work as the bin file do not keep the address offset from the axf. Generating the hex directly from the axf is right but have no checksum...

Content originally posted in LPCWare by pgr on Fri Apr 04 08:57:33 MST 2014 I have bootloader at address 0x0000 that start the application at 0x800 and would be happy to use the same validity criterion as the one used by NXP...
