Description Caleb Crome 2009-07-08 10:09:18 UTC 
I had another kernel oops when programming the MSP, with yesterday's kernel build (home made).  This was on a board that had an incorrect component installed, and *may* have damaged either the MX25 or MSP pin.

However after rebooting, it programmed properly.

What do you think?

-Caleb

Richard: Is this for MPQ or MP?
Comment 2 Richard Titmuss 2009-07-10 09:33:03 UTC 
David is writing a script to clear the msp430 and reboot the system, logging as it goes. This should let us see if this is really a problem.
Comment 3 Richard Titmuss 2009-07-11 07:38:44 UTC 
This may have been caused if the msp430.txt file was missing from the filesystem. I've fixed that bug today. Caleb, could you have deleted that file while testing?
Comment 4 James Richardson 2009-07-11 08:34:40 UTC

It's totally possible.  Or more likely, I power cycled while the filesystem was in an unknown state.  I think sometimes the file will get left at 0 size.

I saw this error a bunch last night when I didn't get the builds right.

So.... I'm comfortable with you marking the bug fixed.
