So, I built a rib lamp using esp8266-01, openHAB and raspberry pi. It has been running without a hitch for 8 months or so. I decide to build another but did not save my sketch or save the process in which I got the sketch onto the onboard micro controller. I know there is some finicky rules that are associated (pull ch_pd high and gpio0 low to load sketch and release gpio0 once sketch has successfully loaded. My issue is eepromm sync error. The sketch verifies but when loading, at the last second, I get the eeprom_sync error. What can I do to remedy this? I'm sure that there is more information that would be helpful in diagnosing this issue and resolving. Please, ask me for whatever info will help. I'm going to beat my head against the wall again tonight when I get home so I can post the full error. Thank you all for helping a noob with your collective plethora of knowledge on this subject

Just to follow up on this. I figured the issue. I had some shorted jumper wires. Got it sorted and sketch loaded. Now in regular operation, the wireless radio intermittently works but cuts out. The red led is lit solid but no blinking blue status light. I fear I may have boinked the chip. I'm trying to control the neopixels with the module. Previously I did not shift the logic level from 3.3 to 5v on the data line and it has worked fine. I'm going to try that. But regardless, once the chip is powered it should connect to wifi and run my loop even if nothing is connected to GPIO2. I did not have this much trouble on my first build
