Erich,
Thank you.
I found that whenever I had problems with GDB, the USB
MultiLink FX would show disconnected. The disconnect was
on the target side only. P&E utilities pointed this out. There
was a couple of times when Windows has reported A USB error.
The MultiLink FX that I am using is a Revision A.
Yesterday I read something on P&E's website which said
that the Revision A units might disconnect from the target.
P&E's solution is to buy a Revision C device. The USB
system has a new design in the Revision C devices.
I would switch to J-Link, except there is no space on the PCB
for the connector. A board spin would be required.
These errors are very unpredictable. On Monday and Tuesday
of this week I had problems. Yesterday it worked fine all day
long.
The only way to fix this is to re-install software. However, the
re-install of the MutiLink driver has failed due to the USB
being disconnected. Not sure what software resolves the
error.
I have not yet contacted P&E to find out if my Revision A
could be exchanged with a Revision C.
