I was able to set up and run WNISP, and then read the code frome the device and verify it (buffer to device). I want to save the hex file to disk, but I can't see how to do this.
It's important to save the original before I upgrade using the code given to me by the firmware people.
This, along with the display of the checksum, is an important feature in a programmer. It helps with version control and, in this case, will save me if the new code is more broken than what I have.
duh -
the answer is "Use FlashMagic".
The (hard to find) download page on the Phillips site says "WinISP - used to program Philips FLASH ISP microcontrollers ( 89C51Rx2, 89C66x, XA-G49)"
As I am using the XA-49, I thought this was the only tool that supports my processor.
This looks like a pretty coo tool.
Back to work!
