I am using pk2cmd command line tool for pickit2, which has options to program only code space or eeprom, but it fails verification always if option other than "delete/program all" is selected, it complains about some particular address when data is not as expected. I tried with different chips with the same result. The very least thing I was hoping to achieve was that eeprom would not be erased at every code change. > > I don't know if it's the same with Linux, but on Windows using the > PicKit2 software you can program the EEPROM directly (on it's own if you > want) by just typing the values required into the EEPROM data window, > then hitting write (untick the "enabled" box next to the program memory > window if you don't want to program that too) > --=20 KPL --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
