I have been working with the Zoom SDK for about a week now and I've not yet managed to run a Win CE image from CF. I have followed the steps outlined in the SDK eval guide but so far without success. The image loads and the checksums are verified but when I issue the execute command there not much response from the device. Here is a list of the debug serial data that comes back from the device:

I am able to get the both the CE 4.2 and 5.0 images to load over the LAN using platform builder and the bootme command - the debug serial output for these seems to go a bit screwy - maybe because I'm using hyperterminal - but the image loads perfectly and runs without problem.

Has anyone any ideas where I might be going wrong?

Thanks in advance,

Andrew
