Ted,
Yes, you're right. I wanted to program the flash and eeprom separately, but,
as you point out, it can't be done on the 8515. I'd never actually tried it
on Windows but assumed it could be  done because the Ateml ISP program had
separate commands for loading flash and eeprom. I guess I was misled.

This attempt with uisp was my first foray into eeprom programming on the
8515. I had assumed that
uisp --segment=flash --erase would erase only the flash, not the eeprom. I
was wrong. Thanks for straightening me out.
