Hi,

Can you please give some details about your hardware configuration? (ie what development board or other hardware). The USB ID only gives us the USB/serial chip model.

Do you know if the device you have works on any of the supported OSes?

Can you please post the output of esptool.py --trace --port /dev/ttyU0 flash_id?

Thanks,

Angus

Hi Angus, sorry for the delay

Yes on Linux it works.

It looks like absolutely nothing is being read from the serial port.

My best guess is that this is a problem with the CH340G driver on FreeBSD, or maybe with the pyserial support for FreeBSD.

You can test the CH340G driver on FreeBSD by using any serial port program to connect to the ESP8266 and 74880 bps, pressing reset, and looking for any serial output at all. You can test the pyserial support for this by running miniterm.py /dev/ttyU0 74880, pressing reset, and looking for any serial output at all.

I don't think there is anything we can do about this from the esptool side, though, if the underlying support isn't sending us any bytes. Sorry!

Thanks, but i am sure the is installed. I but will check

But in my case, something is read (see log):

Still an issue on FreeBSD Users-Laptop 13.1-RELEASE-p3 FreeBSD 13.1-RELEASE-p3 GENERIC amd64. Geting Failed to connect to Espressif device: No serial data received. with the ESP8266 WeMosNodeMCU with CH340.

Workaround: When I use a Prolific Technology Inc. USB-Serial Controller to connect RX and TX instead of the built-in CH340, then it works fine.

So the question is, is this an issue in esptool or in the FreeBSD CH340 driver.

Note the ESP8266EX in the traffic, so the ESP is communicating with the host somewhat.

Is this an issue in the uchcom FreeBSD driver?

Looking at https://github.com/freebsd/freebsd-src/commits/main/sys/dev/usb/serial/uchcom.c, maybe @hselasky, @avg-I, or @thompsa know how to debug this further?
