I need to edit EEPROM hex. Does anyone khow a free hex editor like this: http://www.smarttechnosoft.com/ihex/ The only requirement - automatic checksum calculating.
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. www.galep.com http://www.galep.com/english/software.php
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 regards, mf
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 Jan
Hi I suggest http://srecord.sourceforge.net. This is what I use for any job requiring editing hex files and patching them. Matthias
