48227Re: [SeattleRobotics] MRM trouble!
- Feb 8, 2014James --I think I may have accidentally hosed CPU32Bug on my MRM.I've been trying to get RTEMS running out of ROM on my MRM and have been having a lot of trouble with linker scripts. After doing a ton of reading I think I'm getting a better handle on it, but I think that during my experimentation I may have overwritten part of CPU32Bug as it no longer responds at the prompt or starts programs loaded into the MRM.If I connect to the serial port using minicom I get the following:CPU32Bug Debugger/Diagnostics - Version 1.00(C) Copyright 1991 by Motorola Inc.CPU32Bug>And then it hangs. I've tried this on two different computers to check it's not a dodgy serial port problem.I've tried loading mcbug.s19 from Marks website (http://robominds.com/minirobomind_sw.htm) using the bdm, but no luck.Not that it's any comfort, but apparently you're not the first to run into this...the following is from 10 years ago:
Too bad there's no resolution...Can you tell if the re-flashing succeeds? Is it possible that the modifications mentioned are not compatible? (They sound benign...) There's a footnote at the bottom that specifies 19200 baud -- is that what you're using? Is your BDM cable ok? (Scraping the bottom of the barrel here...)
