So I tried to update my wemo d1 mini (tasmota firmware [https://github.com/arendst/Sonoff-Tasmota] )
and damaged
Serial Monitor output:

l␌␄␃␌␌␄␄␌␌␄␄cl�{�␓��#�␄␄␃␌␄␄␌␌␄␄␌c␄��r�␄␌␂␄␄␌␌␌␄␌l`␃␜␛�␓�ol�{

…and to the infinity.
Is there any way to save it?
i aso tried this https://www.esp8266.com/viewtopic.php?p=67614.
thnx in advance

That’s very little info. What environment did you select in the platformio.ini?

hwarang098tkd · 2019-02-13 21:29:24 UTC

run task–> wemos(upload). i did it 10000 times.
i dont know how to restore it from this state. i have 2 wemos in this condition

maxgerhardt · 2019-02-13 21:34:51 UTC

Can you upload another firmware like https://github.com/platformio/platform-espressif8266/tree/develop/examples/arduino-wifiscan to it? Use the platformio.ini

[env:wemos]
platform = espressif8266
framework = arduino
board = d1_mini_lite
monitor_speed = 115200

hwarang098tkd · 2019-02-13 21:53:44 UTC

i dont know how to run it. sorry.
i downloaded it and added it to vsc.
I added the lines in the specific example arduino-wifiscan.
then?

maxgerhardt · 2019-02-13 21:56:29 UTC

In VSCode, click on the upload button in the toolbar. See http://docs.platformio.org/en/latest/ide/vscode.html#platformio-toolbar

hwarang098tkd · 2019-02-13 22:02:06 UTC

i see. with this folder there are not options in the toolbar . In tasmota folder exists.

maxgerhardt · 2019-02-13 22:04:25 UTC

I think it would be easier if you just created a new project (see here) with the WeMos D1 mini Lite as board and copied the WiFiScan.ino into the new project’s src/ directory.

You now have a main.cpp as well as WiFiScan.ino. Delete the main.cpp. Is this really a new, clean project?

maxgerhardt · 2019-02-13 22:19:20 UTC

Ok then first of all remove the d1_mini_lite environment, the env:wemos already has everything.

I.e. your platformio.ini should be

[env:wemos]
platform = espressif8266
framework = arduino
board = d1_mini_lite
monitor_speed = 115200

hwarang098tkd · 2019-02-13 22:20:23 UTC

ok the same failure.

maxgerhardt · 2019-02-13 22:20:36 UTC

Then put your Wemos into bootloader mode as described in https://www.esp8266.com/viewtopic.php?p=67614. (power Wemos, bridge D3 and GND, press reset button, remove bridge, re-upload)

hwarang098tkd · 2019-02-13 22:25:54 UTC

i did it all. All the ways . Nothing

maxgerhardt · 2019-02-13 22:26:29 UTC

Then try first bridging D3 and GND, then powering it via USB and then uploading (while the bridge is still there).

hwarang098tkd · 2019-02-13 22:27:39 UTC

i did it. pressing the reset btn and without pressing. with short press and long. I smell dead end!!!

hwarang098tkd · 2019-02-13 22:31:27 UTC

without the bridge it fails in 2sec and with the brigde in11s

maxgerhardt · 2019-02-13 22:40:48 UTC

I’m pretty sure it has something to do with the reset method of the board via the DTR / RTS pins (here, here).

You need to do the following things:

ensure the Wemos is in bootloader mode. If you open a serial monitor at 74880 baud, and reset the board while D3 is connected the GND, the serial monitor should show a message like ets Jan 8 2013,rst cause:2, boot mode:(1,7). If this message is there, your ESP8266 is not dead. On Windows you can e.g. use hterm.exe as the serial monitor
see if esptool.py can connect to it. Install it from Espressifs instructions as instructed here. Then see if the command esptool.py -p COM6 chip_id reads out some information. On my NodeMCUv2 it e.g. outputs

esptool.py v2.6
Serial port COM6
Connecting....
Detecting chip type... ESP8266
Chip is ESP8266EX
Features: WiFi
MAC: 2c:3a:e8:06:XX:XX
Uploading stub...
Running stub...
Stub running...
Chip ID: 0x000617b1
Hard resetting via RTS pin...

Options for reset methods for esptool.py are also listed here. If you get one of these to work, we know where the problem is.

hwarang098tkd · 2019-02-15 08:02:10 UTC

they are DEAD.
At 74880
