More trouble with my new ICE. I'm sure this same "problem" has been solved here many times, but my searches led nowhere.
With help from this forum, I learned that ICE does not power the target. Problem solved! Happily programming and debugging attiny85's for a week. Next, Turned to ATMega88... boom.
Failed to enter programming mode. ispEnterProgMode: Error status received: Got 0xc0, expected 0x00 (Command has failed to execute on the tool) [etc., etc.]
Switched back to attiny85's... SAME PROBLEM!!!
I do know about ISP pinouts, having built my own successful adapters. Maybe my "basic" ICE cable w/ 6-pin ISP is bad? But I've since tried the squid cable, following "Table 3-6. Atmel-ICE SPI Pin Mapping" in the current ICE user guide. No luck.
So far as I can tell, my connections are good. Maybe I am missing something about, "[v]erify device selection, interface settings, target power, security bit, and connections to the target device?"
BTW, this is NOT a DBWEN fuse issue. Also, I know the targets are good chips (an assortment of known quantities was tested).
Please help! The poor old dragon never gave me this trouble, and I cannot afford to have wasted $150 (US) on this ICE.
Thanks for your attention.
