Man does this bring back memories. You need to pull the en to ground if I recall upon boot. Then you should be able to access the SPI protocol to load the flash of the model.

The ESP-01 is just the model of the PCB board but its helpful to know the tracing to the esp8266 to then compare it to the ...

This question is specific to LittleFS, not so much Arduino as an interrupt may be triggered to write the data while reading is in progress, however, if LittleFS creates a variable to hold if the data is locked then that will be an issue.

Have you implemented an interrupt/protothreads to handle ...

I am using the built in LittleFS, I did not install any other library for LittleFS.

Is this an Arduino project? I am unsure what you mean by "Built-in".

Are you using Arduino's LittleFS or some other variation? If so can you provide the link to confirm the implementation.

Is it your understanding this is due to a missing .H file that would be added to the blinky.c file for example and not a ".a"(Library file) ?


No, you'd need to #include it in the assembly file that throws those errors.


Thanks, Ive spent a few hours trying to diag the issue. Im going to ...

Potentially you're missing an include that defines those symbols to whatever the Xtensa assembler wants. Sorry, I don't know what include that would be, it's been ages since I touched an 8266.


That is really odd, I fell like I've followed the instructions to a 'T' and have read them multiple ...

Im using the NONOS SDK, are you trying to keep the AP open and accept a specific client or just the first one?

In my case I do the following:
Use struct softap_config to set max_connection=1
wifi_softap_set_config(&softapConfig);

If you register wifi_set_event_handler_cb(wifi_handle_event_cb ...

Are you using RTOS or NONOS SDK?

Greetings Gents, Been looking around all of good and was wondering if anyone knows how to implement a stacktrace for the ESP8266. I see the ESP32 is decently documented on overriding the Panic Handler and I may have to result into digging into the Arduino code to see how they implanted it but my ...
