This is all for tonight... I edited line 33 in write-eeprom.py like this: # time.sleep(0.1) # needs some time to finish write, or fails [Errno 5] time.sleep(0.004) # datasheet calls for ~ 5 ms wait Which gives at 32k write time of ~16 seconds. Sorting out the page write function will make a big difference as well.

@Igor-Silenock I have observed the same behavior with several Omegas2+. That is incomplete, halted boots when powered by 3.3V, then a successful boot when the power was increased to 3.4V. I did wonder if the digital meter on my bench power supply is accurate ... my VOM says it is, but in both cases this is measure of the least significant digit.

Alright, guys thanks for the fast feedback. I hope people with this problem will check their power supply first and get their Omega running. Happy Inventing
