Hi,

Does anyone have any experience with the M50734 Designers board that RCS MicroSystems used to make a few years back ?

Problem I have is uploading code to the board. There is a monitor program running on it and two commands "L" and "U" I presume are for Uploading and Downloading code to/from the board. I've tried pretty much every file transfer protocol under the sun (XMODEM etc.) but nothing seems to work !

Thanks, Tim.

If you make a binary dump of the ROM we can probably work out the monitor command formats by disassembling it.

It may use Motorola or Intel hex format or even some bespoke protocol.

Lee.

Just to say a huge thanks Lee for helping out - really appreciate your time and effort helping out. Tim.
