Checksum calculation of hex file Dear All Forum members, I have implemented Bootloader for PIC32MX device. For error handling I have checked checksum of each row of Hex row received from PC software. But I want to calculate Checksum of ' complete hexfile ' similar to MPLABX IDE. Following is the plan: PC based software will calculate checksum & display on screen so that user can crosscheck with correct checksum before starting Bootloader application OR User can enter corrected checksum on UI & software will automatically compare this with calculated checksum. If anyone knows method for calculating checksum of hexfile please reply. Thanks, Gaurav.

Sector Editor, Base Converter and Hex Calculator for. The Intel HEX file is an ASCII text file. Create a CRC-32 checksum of an uploaded file with this. You can use the calculator above to check this.

Thanks NKurzman & GlennP for your valuable suggestions. Actually I want method to calculate Checksum which is used by MPLABX IDE / IPE while we build our project.

Because when we release any code to production, checksum displayed my MPLABX IDE is the only key for them to ensure that hexfile is not corrupt.
