ESP8266EX Support?

[ghtomcat]

I can successfully flash my ESP32 but not my two NodeMCU (v2 and v3), which use the ESP8266EX Chip.

error: "failed_initialize", details: Error: Unknown Chip

esptool flash_id returns:

I just tested it myself on a node that's not possible to flash using the web flasher:

esptool.py v3.0
Serial port COM3

I added a breakpoint to where the exception was caught:
domexception a framing error has been detected

Can you post what you see on Chrome's Developer console?

Is that all the console shows? No log messages?

[TD-er]

Yep that's all.

[conradopoole]

Yep that's all.

Can you click on the login levels and enable Verbose?

[TD-er]

Not much of a difference:

It's empty, even with Verbose enabled. Do i need to do anything to have more debug output like @TD-er above?

By default it doesn't log to the console. I've just updated the demo to do so e6a198f. So now open the chrome dev tools prior to flashing.

Thanks, now i see the following in the console (with the demo)

[TD-er]

This attempt I held GPIO-0 down and pressed reset.
The attempt before was the same, without reset + GPIO-0 held.

The error has been updated by @conradopoole. It should now include the magic value of your chip so we can add it to the detected list. The demo has been updated.

@ghtomcat can you try it again and report the updated error message.

start-flash-542f194f.js?module:1 Error: Unknown Chip: 0x-F3EFF

[TD-er]

Me too, on one module (with CH340) Unknown Chip: 0x-F3EFF

The unresponsive unit with CP2102 USB to serial:

[balloob]

@ghtomcat this should be fixed in 3.4.2, live now in the docs. Can you try it?

[TD-er]

Does work with the node that gave the unknown chip error before.

The "timeout" unit still remains unresponsive, but had not expected it to be fixed by these changes.

Works now, thank you!

Did you get the CP2102 working? if have the same issue with ESP8266EX modules

[ghtomcat]

@degraafm76 yes, after the update it works for cp2102 and ch340

[degraafm76]

@degraafm76 yes, after the update it works for cp2102 and ch340

I see, but not for ESP8266EX modules.
