ESP8266 Troubleshooting Make Error

[IanAber]

I am getting an error at the end of flashing an application to an ESP8266. The code compiles and appears to flash but finally returns an error. How can I figure out what the error means and what its cause might be? The final error is Make Flash Error 134. What does that refer to? Where can I find more information on Error 134?

make: *** [flash] Error 134

[IanAber]

I finally found the problem, or at least the solution.

I deleted the 'out' folder in the project and executed the Flash command. This time it recompiled everything and successfully ran.

I still have no idea what the error is telling me or why it should happen but even a full clean did not fix it.

@IanAber Sorry for the lack of response. The error is from GDB (debugger) which means code is built with ENABLE_GDB=1. Just run make ENABLE_GDB=0 to revert to normal.

See also https://sming.readthedocs.io/en/latest/_inc/Sming/Arch/Esp8266/Components/gdbstub/index.html.

The error you see is from the debugger. Running with make gdb V=1 might give more information about the problem.

Closing as issue resolved.
