These are common editors which edit any binary files. But I need editor 
which edits Intel HEX files used to program microcontroller flash and 
EEPROMs. It is possible to edit them with notepad, but calculating the 
checksum is annoying. The above mentioned editor calculates checksum but 
I hope to find free one. :)

The control-software galep32.exe for the GALEP eprommer (Conitec).
Imports and exports all well-know file formats and calculates checksum.

1. Open the hex file in a text editor, note the starting address and 
close it again.
2. hex2bin
3. use your favourite hex editor and edit the binary(indeed, they should 
call it bin-editor??)
4. bin2hex with correct starting address

It's easy to write a small commandline tool parsing a given file and 
fixing the checksums. The whole format is documented :)

I've done that once to automatically add CRC's to a firmware, but don't 
have access to it any longer :(.

This will not work if there are "gaps" in the memory locations
specified by the individual load records.
For instance
mem 0000-07ff some data
mem 4000-4007 some other data.

also some hexformat (motorola S1S9 for instance) contain
records with other data such as the transfer address where to start
program execution

Hi

I suggest http://srecord.sourceforge.net. This is what I use for any job 
requiring editing hex files and patching them.
