I am VERY interested in the F1688 Bootloader project. I have a specific need for one, so that the client can change the 688 firmware whenever needed. It might be very helpful if you make 1 or 2 more registers available for debugging, where you can press the reset button, and if those registers are not the DEFAULT value, let them be read by your bootlegger as a primitive debug tool. The way it would work is to copy to these registers anything valuable you'd like to see, or verification of a pathway (by setting bits in the debug register as the particular routine is passed through) I'll be glad to help you guys debug or verify the Bootloader; having a card made right now... --Bob -- Replier: Most attachments rejected -------------- Bob Axtell PIC Hardware & Firmware Dev http://beam.to/baxtell 1-520-219-2363 -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
