Exceptions and stack dumps with NodeMCU

Message

Hi all,

I have testing a NodeMCU v1.0 board I have received lately, and have found issues with R107 and also R106.

I have tried all sorts of different configuration for power, to rule out any issues with USB power instability on the NodeMCU, and am currently running the board with a separate PSU hooked to the breadboard, so there is nothing connected to the USB port, as I have connected another FT2232-based adapter directly to the RX/TX pins on the NodeMCU pins.

So power supply should not be issue.

This is what I got after loading R107:

Code: Select all

After a while, the ESP reboots for no apparent reason.

Out of curiosity, I compiled and loaded an older R106 build, and I also have issues there:

I now wonder if there is any garbage left somewhere on the flash chip, maybe, and that causes the reboots. I have flashed a number of times a blank file I have created for the 4MB/32Mbit flash, and have used esptool.py to flash it. Still having the issues after compilation and flashing from the Arduino GUI.

I am really scratching my head now as I have no clue about what to do next.

Anyone with a suggestion for me? NodeMCU looks like an excellent board for my projects, with the reset and firmware update buttons, but it's not been much stable so far...

Thanks,

Luca

Rubbish left in SPIFFS, type 'erase' on serial interface if you can get to control it - when you can catch it live. Also had that last night, the problem was that I mis type the SSID....

or try crossing the serial pins, will erase too (multiple times mentioned here in the forum, you find this with the forum search...)

Unfortunately I tried all of methods you mention, but the issues are not solved.

Here is longish dump of the latest tinkering I have done on my SparkFun ESPthing:

I have both given the erase command, and connected together the TX and RX pin, which triggered the "FLASH: Zero Fill Sector" sequence followed by the "FLASH: Settings saved".

Still, this did not solve the issue.

I am very open to any other suggestion you might. I am good at tinkering on both my OS X and Linux machines, if need be.

Many thanks,

that looked good....
it seemed to work for some seconds...
do you have anything connected?
may post a picture of the device?

the device I am doing the debugging on right now is a SparkFun ESP8266 Thing:

https://github.com/sparkfun/ESP8266_Thing

The problem is that I am having the same issues on pretty much all the different ESPs I have here on my desk, from an ESP-01 to a -07, and the NodeMCU v1.0 with ESP-12E.

Is there a way to fully zap clean an ESP8266? I am afraid that some leftover in the flash gets in the way... I have tried to flash a blank file the size of the flash by doing this:

Code: Select all

$ esptool.py write_flash 0x0 blank512.bin

but this did not solve the issue.

Any hint?

Thanks,

Luca

after flashing a first firmware with a minimal ram-config,
you can see in the serial-monitor (start before flashing) the erase-process,
it runs longer than the flashing-finish message!!!
take your time and wait for the end.
make a cold reboot (power off/on).
go to serial.
issue "erase" or "reset", wait to finish.
cold-reboot.
go to serial monitor.
issue "settings"...

this worked for me...

setup the easpeasy like normal (see wiki).
check in status-page the 'real'-ram size.
flash a new firmware with this 'real-'-ram size (wait for erase to finish)..

see if this works ... i would be glad, if it helps you...

thanks tozett, I have done what you suggest many times, including reflashing and erasing/resetting also using the TX/RX data lines trick (thanks for the suggestion!) but the issue is still there. This is on multiple devices, an ESP-01, an ESP-07, a NodeMCU v1.0, and a SparkFun ESPthing.

As a test, I have reflashed my NodeMCU v1.0 with R107 and erased it and left it unconfigured the whole night, with a serial monitor running on the console, and I could see the normal messages in the log, the NodeMCU never rebooted.

But the moment I configured wifi over the serial console using wifissid and wifikey, or when I connected to the ESP_0 ssid and accessed the initial configuration GUI at 192.168.4.1, then the board would begin the reboot loop.

I have also added a few comments to this other thread, and Dave was suggesting that I might have bricked my boards by using GPIO 9 or 10:

http://www.esp8266.nu/forum/viewtopic.p ... 7298#p7298

The testing continues... thanks a lot for your help!

Ciao, Luca
