TS0202_TZ3000

[claviger-pc]

Is there firmware available for testing? I have a newer version of this device (dated 2024-08) and I would be happy to test. It does not have uart pads on the back, but I can just solder straight to the module.

Zigbee does not provide testing capabilities.
UART operation requires constant operation of the chip.
And what is there to "test" via UART?

[claviger-pc]

By testing, I mean flashing the module and seeing if it works with the newer revision. UART I would only use for flashing, not for testing.

You mentioned that you were developing firmware for this module, but I did not find anything about it in the whole repository.

The chip has a great hardware single-wire debug interface in the form of Telink SWire at 2Mbit/s. Through it, there is access to all SoC hardware. Analog of JTAG.

[claviger-pc]

yes, I have used that on other devices for the one-wire flashing. Do you have firmware for this TS0202_TZ3000? or any source code?

[pvvx]

If you have a device, then you can read its firmware. The chip has no protection against reading via SWS.

Here I posted the firmware I read from https://pvvx.github.io/TS0202_TZ3000/

I'm sorry maybe I was not clear:

Do you have custom firmware or are you developing custom firmware?

[pvvx]

For TS0202 (_TZ3000_lf56vpxj) I did not make firmware. They work more or less normally.

I make firmware only for devices that I use myself. Firmware for some added devices was created with the help of information provided by other people.
This is not a commercial project. Its implementation requires me to spend time and money. Nothing more.
I can’t post everything, as it would require even more of my time for support.
