< jeffdi> < Tim Edwards> My other dies are worse than the fi open-source-silicon #mpw-2-silicon

@jeffdi @Tim Edwards My other dies are worse than the first. I'm having trouble getting the first chain to completely program. It usually stops around bit 8-11

Have you tried calibrating at a vccd1 voltage of 1.43V?

Yes

1.42 actually, I'll try 1.43

1.45 seemed to do better than lower

Your "best part" should be able to be configured properly for test, but the existing software for the configuration builder needs to be modified, as I mentioned in the other thread.

@Tim Edwards We were using the best part yesterday during our call. There's a chance that something else might be affecting it. I have a wire on GPIO0 that could be loading it extra and causing pulses to be missed.
