Has anyone ever used picloader? I programmed a 16f877 with it and made a very simple program, but everything i try to send to the pic after issuing an U and waiting for the ready signal, returns: invalid record All commands work ok, so serial and other stuff are perfect. The problem is just in uploading the code into the flash. By the way: I'm not using Hyperterminal as told in rfarmer page. I'm using minicom, a Linux terminal emulator with all needed configuration.
