Hi - my firmware team is seeing the "failed to measure TotalIRLen" error regularly on our SM470R1B1M development. Can anyone who has seen this or was involved in fixing this situation last year for Maxim T. comment on how it can be improved? We have found several things that appeared to make it better (disconnecting other communication channels, holding our tongues just so etc.) but the problem keeps coming back. It is not that we can connect 1/2 the time and that it alternates; when it is bad it stays bad. Per the suggestions above, 1.8 V is good, J-Link tool is professional version, clock is oscillating, microprocessor has shown the problem when new and when previously programmed.
Help is appreciated - thank you.
EDIT: Andrew I moved this post to the High Reliability forum - the SM470R1B1M is a hi-rel product not a Hercules product. Sorry for the confusion.
