Jtag Ice MKII

2009-04-08 by David VanHorn

Yet more fun with tools..I've noticed two new things in the last couple days.

1: WDT always on, even though the chip is NOT programmed for this.
Do a build and run, or reset, and notice that the WDE bit is on at reset.
Go out of debug, into programming, check the fuses, and WDT always on
is NOT set.
Then SET the fuse, and Reset the fuse, no help.
Erase the chip.. No help..


2: Do a build and run, and after the chip is programmed, it boots up
running the previous software version(!) indicated by a screen message
that does not exist in the current build.  I verified this by checking
the hexfile for the text.

Sometimes, completely exiting studio, resetting the target, and
powering off the ice will "fix" these for a while, sometimes not.

Can anyone suggest a workaround?
Target is a 20 MHz M644.

There is no computer problem which cannot be solved by proper
application of a sufficiently large hammer.
