Help please,
I have just bought a pre-assembled Handy board, powered it up connected it
to com2 on a dos PC and successfully downloaded IC. The problem now is that
after that I disconnected all power to the board(including batteries),
powered the board up again after about 15 minutes and it will not download
IC. The error message is as follws:
Downloading 256 byte bootstrap (229 data)
............................................................................
......................
Expected 141, received 91, after 60 chars received
Perhaps the board was not connected properly or not in download mode.
I have tried several times, each time making sure the board is in bootstrap
mode and it will not download at all.
Is it a problem with the machine serial port (I am specifying com2 in the
command line)?
or
Is it a problem with the on board components?
Any suggestions would be welcomed
Thanks in advance
Andy Burton
