Better flashing instructions

[yetanothercarbot]

I received my T-Zigbee boards today. I soldered headers onto one and connected it via USB with the dip switch set to the C3; it failed to enumerate (in fact, it knocked my USB headphones off the bus!).

IO9 isn't broken out so I'm unsure how to place the ESP32-C3 into download mode so that I can flash new firmware.

I have other questions too, but closing #2 should solve those.

need to use u2t:

I see. That's unfortunate; the price of shipping is nearly the price of the U2T itself haha. Thanks for the quick reply.

Is there any way to flash using a FT232RL USB TO TTL? If yes, how to connect the wires?

or using this cable?

You can use USBCOMFlashTx.html in https://github.com/pvvx/TlsrComSwireWriter to flash the TLSR8258 firmware.

But FTDI USB-COM chips don't work!

You can use t-u2t or ch340.

Below the connection diagram：

What about PL2303HX using 3v?

@camnop This PL2303HX has no RTS.
