- Hi Fred,
-
- I am trying to get a head start on my miniboard project while I wait on
- Greg Ratcliff's boards and Dave Dunfield's C compiler to get here.
-
- I have two Motorola M68HC11EVBU boards that have 68HC11E9 chips. I can
- get PCBUG11 to work with them if I disable the onboard BUFFALO ROM and
- reset into Bootstrap Mode. I have been trying to get DL, MON and IC to
- work with the EVBU with no success. I assume that this has to do with
- the serial line echo weirdness mentioned above?
-
- Are there configuration mods to your programs to disable the
- requirement for echo? Do I need to re-compile the programs? Do the E9
- parts have the right amount of RAM/EEPROM for this to work at all?
-
- Will the miniboard work with any of the 52 pin FN parts? I have
- several of the 12K MC68HC711E9 chips. (Assuming I can program them)
-
- Thanks for the work so far. (Neat schematic!)
