Hi,

there is a driver for linux and windows, but event though it = sort of works on FreeBSD,
the magic needed to flash the = firmware on newer esp32=E2=80=99s is not working.

I also bought USB-C based = UART-to-USB adapter from Waveshare with
CH343G chip and = use it for ESP32 flashing.

This chip is a = bit tricky and I have noticed it is less reliable for
initial flashing on a custom ESP32 board (boot mode selection = using
RTS/CTS pins). It sometimes fails, while older = USB-UART converters
works fine.

What are your problems exactly?

Are you sure = this is not the custom hardware design issue?

no, it=E2=80=99 happens on several = esp32s specially from m5stack

Do you have = Reset and BootSel pins on your board that you can trigger
by= hand in order to help USB-UART cable?
this particular onw, m6stack = black/basic, has no gpio-0 available to enter
download mode, = the older models have no problem with the usb-c

What is your magic that you need to do in order to flash the = chip successfully?
see the = above.
some other boards I just connect gpio-0 to ground, or = have to press a button before power on,
but I can flash. Also, = as soon as I manage to flash, I can continue flashing over the = air.


Does standard operations (UART = CLI) work as expected?
again, all = boards/thingis i have no problem reading the console, and even = writing

Did you take a look at man = stty and use stty crtscts <port> / stty
-crtscts = <port> to see if that fixes anything?

the = initial (or when my software crashes) flashing is done via a python that = does all the magic.

well, it does feel = better knowing i=E2=80=99m not the only one with this problem = :-)
