Issue on ESP8266 NODEMCU
pyr0hax opened this issue · 7 comments
With the latest build I am having an issue where after flashing, it will not take any commands.
I had the same issue on one of mine, I just selected full erase when writing the sketch again and it worked after that.

Lol I found it. Thanks. Going to try this now and see what happens
I'm seeing the same issue here, using NodeMcu V3
Have tried using erase settings to no avail:
Same issue here. Sometimes it is Exception 0, other times Exception 28.
I have tried erasing the flash. Tried a different ESP8266 module.
Setup is: Mac OS Big Sur, Arduino 1.8.13, board manager esp8266 3.0.0, ZiModem 3.6.3
Here is what Exception Decoder says:
Exception 28: LoadProhibited: A load referenced a page mapped with an attribute that does not permit loads
PC: 0x4000bf80
EXCVADDR: 0x00000000

Same, with both a commercial C64wifi adapter and my esp8266 boards, and both the latest and the specified versions of Arduino IDE. I found some older firmware that works but I would rather get this going as it is more feature-rich

Which ESP8266 lib is everyone using?
I'm still on 2.7.4
Again, thanks to Dabo for figuring out that the head revision of the 8266 libs is no longer safe to use. I've updated the README with his recommended rev.
