Hello! Is there any way to flash a Tasmota-flashed ESP8266 chip with openbk over OTA? Do I need to upload via serial, or can it be done over OTA?

did web install on 4mb 8266 and OTA attempt with 2mb OpenESP8266 just fails with Code: TextLog in, to see the code if running 4mb Tasmota Code: TextLog in, to see the code Code: TextLog in, to see the code I'd give that a no, serial flashing required

I remember that @insmod said the partition schema is different and it would require a prepared binary just for Tasmota work around.

I am creating multiplatform open source firmware (Tasmota replacement), right now supporting BK7231T, BK7231N, XR809, BL602, W800, W600, LN882H and soon supporting RTL and W701:
