Getting a WDT Reset Loop #10

Closed Cellgalvano closed 3 years ago

Cellgalvano commented 3 years ago

Hi!

I tried the BMP using a prebuilt binary I found online and it worked great. Currently I'm trying to build the newest version with Live Expressions.

I can build the firmware and flash it to a NodeMCU (ESP8266-12E) and I always get into a boot loop caused by a watchdog reset.

On the UART I get: rst cause: 4, boot mode:(3,6) wdt reset load 0x60000014, len 8, room 16 tail 8

As a build system I'm using a fresh Ubuntu 20.04.2 VM with the xtensa toolchain version 8.4.0 (2020r3).

Hope someone can help. Best regards!

I finally got it to work on multiple ESP8266-12E modules!

In my case I needed to do a "erase_flash" using esptool.py before running "make flash". The modules were used in another application and the flash held some kind of unrelated data.

Before I would close this issue I would life to know if it would be an improvement to change the "make flash" command to erase the whole flash before writing the image?

Best regards!

You can also run make erase_flash

That'll do I guess!

Thank you! I will close the issue now.
