v2.04 Causes Resets

[espruino-discuss]

Posted at 2019-12-08 by hungryforcodes

Hi, I'm just posting this in case anyone else experienced this, but when using v2.04 on some largish code (40K minified down to 20k), I get resets with exccause 3.

ets Jan  8 2013,rst cause:2, boot mode:(3,7)
load 0x40100000, len 2408, room 16
tail 8
chksum 0xe5

2nd boot version : 1.6

  SPI Mode       : QIO
  SPI Flash Size & Map: 32Mbit(1024KB+1024KB)

  "reason": "exception",
  "exccause": 3, "epc1": 1073799076, "epc2": 0, "epc3": 0, "excvaddr": 1076285788,
  "depc": 0 }
Running onInit()...

This seems to be caused by a LoadStore error -- I found this description to go along with it "Processor internal physical address or data error during load or store".

If I flash back to 2v03, everything is fine. I'm using a totally normal 4MB ESP-12f.

Have you called make erase before flashing the new firmware?

Latest build of Espruino works stable for me.

>process.env
={
  VERSION: "2v04.274",
  GIT_COMMIT: "1921e46c1",
  BOARD: "ESP8266_4MB",
  FLASH: 0, RAM: 81920,
  SERIAL: "84f3eb0d-17d4",
  CONSOLE: "Serial1",
  MODULES: "Flash,Storage,hea" ... "r,crypto,neopixel",
  EXPTR: 1073643636 }
> 

Edit: Including save().

OK good! Thanks for checking that! It might be I just have a board with flakey flash. "storage.compact()" is also not working on it -- triggers a wdt reset -- so that points to flash as well. I'll try a couple of other boards and see what happens.

Cheers,

Maybe switch from qio to dio when flashing.

Yeah I got this working finally, so that's good. I've always used qio and dio interchangeably, but on this board dio worked finally. Anyways thanks again! :)

Hey @MaBecker!

Maybe switch from qio to dio when flashing.

Using qio I wasn't able to connect and it was looking like this:

$ espruino -b 115200 --no-ble 
Espruino Command-line Tool 0.1.20
-----------------------------------

Using first port, {"path":"/dev/cu.wchusbserialfa1340","usb":[6790,29987]}
Connecting to '/dev/cu.wchusbserialfa1340'
No result found for "process.env" - just got ""
Unable to retrieve board information.
Connection Error?
Connected

Using dio I am now able to connect but looks like it is reseting the board on every connect.

Any idea?

Hi,

what’s the flash_id and chip_id of your board?

I just tried another one marked 'AI Thinker' and that seems to work ok.

>require('ESP8266').getState()    
={ 
  sdkVersion: "2.2.1(6ab97e9)", 
  cpuFrequency: 160, freeHeap: 11144, maxCon: 10, 
  flashMap: "4MB:1024/1024", 
  flashKB: 4096, 
  flashChip: "0xe0 0x4016"
 }

This is a 'doit esp8266' board which is giving me trouble (tried 2v00, 2v04 and now running the master build). Same results - resets on connection (when flashed with dio, doesn't connect when flashed with qio):

>require('ESP8266').getState()
={ 
  sdkVersion: "2.2.1(6ab97e9)", 
  cpuFrequency: 160, freeHeap: 13296, maxCon: 10, 
  flashMap: "4MB:1024/1024", 
  flashKB: 4096, 
  flashChip: "0xc8 0x4016"
 }

Yes, the AI Thinker work great with qio, check this page for details on flash_mode.

I was testing some EPS01 which gave me a hard time too.....

Result: some work with dio and some only with dout

That's why you can add some flash setting with make

• ET_FM= valid values for flash mode are qio, qout, dio, dout

• ET_FS= valid values for flash size are 256KB, 512KB, 1MB, 2MB, 4MB, 2MB-c1, 4MB-c1, 8MB, 16MB

Check this page for further details

Thank you @MaBecker for all the info!

I'll try the dout as the last thing...

Then I guess I give up as I am starting to think that the USB serial is strange. Appears to be loosing characters during ./espruino --no-ble ./index.js. Sometimes it gives syntax errors during that on that one particular board.
