It appears that the PUYA flash chip is being adopted by a growing number of manufacturers of the esp8266 modules. My most recent purchases of esp-12 modules from 3 separate suppliers have all had the PUYA chip on-board (for a total of 30 modules). The issue is that Arduino IDE x.xx sketches using any 8266 core can not currently write to SPIFFS on modules with this chip.

Any ideas?
