Revive uzb stick by uart?

Post by khag »

Hi

wondering if its possible to reprogram/revive a bricked uzb stick by uart connection and if possible to know what pinout needed for it?

Also if its possible to reprogram the chip by z wave programmer by silabs:

my update came as far as this, afterwards the stick wouldnt work:

Code: Select all

If USB is not available anymore, then no way to use USB ;(

UART/SPI methods requires special toolings and software.

Hi

Yes I am aware that I can't use the USB anymore, but as asked earlier. What's the pinout required to flash the chip by uart?

I have a USB to ttl adapter for the communication, but there doesn't seem to be any document telling which pinout to connect to, on the board for the Uzb stick you have rx, tx, 5v, 3v3, rst, grd and sck.

Have tried with 3v, grd, rst, tx and rx connection but no luck.
