ESP12-E : Panic from umm_malloc ( Inconsistent between similar ESPs ) #1699

uncletammy · 2016-02-29T00:01:56Z

Basic Infos

I have two ESP12E modules. One came mounted to a NodeMCU breakout board.

The other is a generic board that I have wired myself (see pics for wiring)

I am able to upload sketeches to both of them using the Arduino IDE (version 1.6.8 with version 2.1.0 of Arduino core for ESP8266).

Both boards produce identical output from the CheckFlashConfig sketch. They behave the same until I try to use a sketch that connects to Wifi. Then, the NodeMCU board works but the generic board panics. Sketches that don't connect to Wifi work fine on both. My operating system is Debian (Jessie).

This is being continued from #1675 at the request of @Links2004

"Flash ide speed: 80000000" never worked properly for me. Did you try 40 Mhz?

uncletammy · 2016-02-29T00:07:40Z

@kaeferfreund, I have tried both 40Mhz and 80Mhz but I got the same results :(

@tablatronix, were you able to reproduce this? I don't quite understand your comment.

tablatronix · 2016-03-05T03:29:56Z

Yup wdt resets, but I dont have exceptions handy, ill try to enable debugging and get any stacks if they help. Ill install gdb if i have time also. And i was getting a similar issue with the serial terminal example so ill probably be debugging stuff anyway.

wdt reset

If i erase_flash it works.... until I reboot then it goes into loop again.

uncletammy · 2016-03-06T03:06:20Z

@tablatronix, I get similar behavior and It's always right around "delete old wifi config..." . It also goes away (for a while) upon erasing the flash.

tablatronix · 2016-03-06T03:18:28Z

Looks like it immediatly calls wifi.disconnect after, which might be causing some bad flash writes. This might be another bug already known. Hmm

tablatronix · 2016-03-06T22:49:05Z

Ok i reverted to 2.1 worked fine.
Wiped clean and installed latest dev, also working. Fine.

I did notice that my flash check is correct now., it was not matching before, but. most stuff was working fine and my settigs were correct. Ill keep and eye on it and see if it corrupts again or whatever.

wkraus · 2016-04-03T09:27:55Z

@uncletammy Hi, I am getting exception(2) as well whenever I use WiFi.begin(...) . Have You solved Your problem yet?
I use a WeMos D1 - old version, running well if not connecting to WiFi. even WiFi scan works.
Arduino 1.6.8 - core 2.1.0

uncletammy · 2016-04-05T19:37:43Z

@wkraus, I'm not certain but I think I had two separate problems. One was definitely solved here

The other one which was the crash immediately upon calling WiFi.begin seems to resolve upon using the suggestion by @tablatronix. Simply use esptool's erase_flash command esptool -p <port> erase_flash

Over the past month I have flashed 100 generic ESP modules. I cannot find a pattern in the frequency of occurrence. It seems random. I do know that once I addressed the issue that I've linked above AND turned off serial logging completely, the problem almost never occurred. When it did though, the erase_flash command did the trick.

wkraus · 2016-04-06T09:53:30Z

@uncletammy good advice. I will try erase_flash but don't know how to do it. Can I put it into an arduino sketch?

uncletammy · 2016-04-12T00:33:36Z

@wkraus, no. You have to use a command line tool called esptool.py. See https://github.com/themadinventor/esptool for installation instructions and usage.

tablatronix · 2016-04-12T12:35:48Z

I don't know your platform but for example windows.

arduino\hardware\esp8266\tools\esptool\esptool.exe

From command line run esptool
esptool -cp <port name> -cd ck -ce
eg. esptool -cp COM7 -cd ck -ce

if you have esptool.py and python
esptool.py -p <port name> erase_flash

wkraus · 2016-04-16T14:26:13Z

Thanks for Your help, I was out for a week and will be out again next week but will try it as soon as possible and post a comment.
