Trying to write a console app in pelles c that will send the cmds and data to an AVR109 bootloader to burn a page into flash. I think the cmd sequence is: A hi lo of word addr, then 128 loops of c lobyte C hibyte to put data in the mysterious invisible page buffer, then an m cmd to write the page buffer at previous A cmd word addr. Repeat for 124 pages. If this is right, I cant make it work. If its wrong and you know how to make it right, please tell me.
