  • JFlash adding interrupt table checksum for NXP chips

    I am working on several applications for NXP 2136 and 2148 chips using IAR and want to use JFlash to program the chips. I am using IAR for development and am using the linker option "-Ointel-extended=.hex" to create the hex files. These hex files do not include a checksum in the interrupt table that is needed for the application to run.
    My problem is that JFlash doesn't add this checksum to all of the hex files. It adds it to some, but not to all of them. How can I get JFlash to add this checksum automatically to all the files like it does to some of them?
    Thanks!

  • Hello Viscell,

    J-Flash should automatically insert the correct checksum from 0x14 to 0x17 for NXP LPC 20xx - 24xx devices.

    If this is not the case can you send the J-Flash project file and hex file to support@segger.com ?

    Thanks,
    Rolf
