Hi,
I am using the MCB1700 board and both Flash Magic and some software I wrote myself to try and get ISP programming working on COM0
Firstly, I am quite confused about jumpers. From reading the schematic I would say Reset and ISP jumpers need to be in but according to: www.keil.com/.../mcb1700_su_configuring.htm ISP jumper being on disables ISP functionality
Also no matter what I do with Flash Magic I cannot get it to work! I have exausted google and cannot see what I could be doing wrong.
With my own application I get to the point where the device sends back "Synchronized" but when I reply with "Synchronized" it then sends back a bunch of random data. Same seems to be happening with Flash Magic if I use a port monitor, after sending "Synchronized" it gets random data.
On my own application this data seems to always be the same - starting with d?
Anyone have any idea about what could be going on? Is it possible that the bootloader is corrupt? I know the application I have written could be complete rubbish but it does respond to the initial "?"
Thanks
Gary,
Thanks for the reply. I played some more and I found that I had to open ISP and RST to get the thing to flash update. The instructions given in your initial url link from Keil seem to contradict themselves! Oh well at least we can both poke code into the thing know!
Regards, Michael.
