The dump seems to be ok.
It's shifted up by one byte, thus I had to remove the first byte before loading it into IDA. You may consider changing the file.
Result:
Signatures apply, idc-scripts find functions and basic startup is what I expected. The dump is ok.
Note: The dump ends early. Everything needed for porting is there, though.
Note2: Firmware Version 1.01B
Cheers.
