with a 68hc811e2 and a BotBoard2 with a 68hc11a1. Both boards
give me the 0xff verify error.
I'm going to keep playing with this. Thanks for your help.
- Ok. My machine.db11 now reads:
and my debug.db11 reads:
and when I run db11 -f debug.db11 I now get:
RESET, then press Return to continue:
Bootloading 256 bytes to boot RAM
download verify error on boot file:
first 255 of 256 bytes ok, maybe all.

republish ASAP, check my DB11 webpage.

size of the binary data - 860 sounds right.
