I've successfully used the USP-ICP several times to program protypes projects for the P89LPC931.
I started a new project and successfully programed the part. Then I added some code, Keil reassembled w/o errors or warnings, and tried to reprogram the flash at which time a "Device does not support operation" window popped-up. The status bar at the bottom of the Flash Magic UI typically shows programming stopping at 0x0740, although I have seen some other addresses.
I changed the micro - same thing. Then I successfully reprogrammed the flash with some previous, larger hex files. The code also runs fine on a EMP900 emulator.
I commented-out the part of the code that changed since the last flash - didn't help although I'm not 100% positive I didn't miss something.
UART timing isn't an issue.
I posted at the teamfdi website an and a software engineer there suggested I post here thinking there may be a Flash Magic software issue. I have the latest firmware in my USB-ICP (downloaded yesterday) and Flash Magic 5.61.
I need to ship my prototype, but can't program the part.
Help please!
