Demo not working with Wemos D1

[Hotaman]

I'm using Wemos D1 esp8266-2M w/18650 Lipo module. This is my first attempt to use MongooseOS so I'm going through the quick start. Just installed mos tool v2.2 so everything should be fresh on the release tag (OSX). I had micropython installed and working fine on this module. I did use esptool to do a full erase of the flash before trying out MongooseOS

After flashing the demo-js app to the module I get the following two issues:

Error during boot: [May 25 10:36:20.512] mgos_init Init done, RAM: 51736 total, 41216 free, 40568 min free [May 25 10:36:21.397] LED GPIO: 2 button GPIO: 0 [May 25 10:36:21.408] at init.js:24 [May 25 10:36:21.410] MJS error: [Timer] is not defined [May 25 10:36:21.413] mgos_aws_shadow_init AWS Device Shadow requires MQTT [May 25 10:36:21.430] mongoose_poll New heap free LWM: 27496

No Timer defined so no flashing LED

Second error occurs when setting up WIFI: [May 25 10:37:10.916] Getting configuration... [May 25 10:37:11.490] Setting new configuration... [May 25 10:37:11.775] Saving and rebooting...

I also tried to edit the init.js file and save it to the device which also gives an error.

File fs/init.js saved. Server Error: {"error":"(400) failed to open file \"init.js\""}

probably runs our of space... we use smalle FS on the Wemos D (128K instead of 256). can you post full boot log?

this is what I get after the flash process:

How do I set it to use small FS with the demo?

[Hotaman]

the results from calling Sys.GetInfo:

{ "app": "demo-js", "fw_version": "1.0", "fw_id": "20180514-130059/???", "mac": "5ECF7F6E26B5", "arch": "esp8266", "uptime": 3666, "ram_size": 51736, "ram_free": 35692, "ram_min_free": 24592, "fs_size": 113201, "fs_free": 1255, "wifi": { "sta_ip": "", "ap_ip": "192.168.4.1", "status": "disconnected", "ssid": "" } }

seems to indicate a 128K FS with 1.2K free

you need to remove stuff from fs. i believe UI has a file manager in it, try removing unused JS APIs.

[Hotaman]

OK, I've had some time to do a little testing on this one. Here are the results so far:

ESP8266-07 module Raw module, custom PCB (1 MB flash): Works as expected!

ESP8266-12 module Huzzah, NodeMCU, etc. (4MB flash): Works as expected!

ESP8266-12 WEMOS D1 MINI with LiPo (2MB flash): Does not work reliably. Mixed results depending on unit used (I have tried 4 different units) Some work once or twice, some don't work at all. I have compiled the Demo-JS project with fewer files on the local FS, this has no effect on behavior. Reflashing after initial device setup (and flash) rarely works (serial port closes). Sometimes I can save an updated file ONCE, then never again. If the demo ran before the file update, it won't after the update. It looks like the local FS gets corrupted. I'm running MicroPython on these modules until I can figure out how to get MongooseOS to run on them. I'm closing this issue since it appears to be specific to this module so perhaps I just got a flaky batch of ESPs.

Many people are having this problem, including me, with Windows and Linux, and different boards.

I am also facing the same issue on nodeMCU v0.9 but it's working like a charm on ESP32 devkit c v2. @rojer
