Wow, what a drama we had the last two weeks!
You might've followed this in the last news thread...
A short summary:
I wanted to work on the tester script and test all the PCBs we have here - but unfortunately, when I started, the unit froze.... even though we thought the 4GB RAM should now be working!
What had happened? Well, you can follow the full drama on the mailing list and on the last news thread, but here's a short summary.
Apparently, the 4GB RAM boards workec without any freeze as long as you stress the RAM and system - which was what we tested. That's why we thought the 4GB RAM freeze was fixed...
But as soon as it was just sitting around idling, it froze after usually 10 minutes.
Pretty weird, huh?
Yes, we thought that as well.
So we made multiple tests, trying to get to the bottom of this mystery... it most probably has something to do with wrong timing settings, so these need to be checked.
Disabling the DLL function of the RAM chip makes the system run stable and without any freezes!
While this might not yet be the best and proper solution, it's one that works. Tweaking and fixing things can always happen later.
Well, this means I can finally work on the testing scripts... and test all PCBs I've got here.
October 17th will be the day when I visit the plastic exhibition in Germany where I will check for various plastic materials together with UniquePlast and hopefully find the best one for the Pyra.
This was just a quick update / summary of what's going on - back to testing
