Hello,

You have to download the IC in download-mode again. All memory (32K volatile
SRAM) will be lost after you disconnect all the power from the board.

However, if you just turn-off the power (without removing power adapter or
batteries) of the board , all memory content will be fine. Interactive-C
will boot again once you turn-on the power switch.


Thanks and Best Regards,

Patrick

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
