STEVAL-WBC86TX -> Bricked accidentally, any chance of recovery?

[AnkhInnovationsLLC]

Hello,

So I recently received the dev board STEVAL-WBC86TX and was quite impressed with the features. Accidentally the wrong config ID was written to the board. Now I cannot connect to it again using the Windows utility.

The USB to I2C appears to be working normally, but there is an error in the log and the device never connects successfully in the GUI, thus, I cannot flash the original config and nvm patch files from the website, provided as STSW-WBC86FWBPP.

[TX]WBC86 connection ex: Wrong config id 0xDA06 and patch id 0x0000 for TX"

I thought I could edit WBC86.json.enc, which probably contains which ID and such... I'm guessing this is encrypted json.

Is there a way to hard reset this chip to restore connectivity to the dev board?

Hi @willzhou you rock!!!

It worked perfectly.

 

Is a similar tool available for the wbc 86?

Glad it is working, it is suitable for all wireless charge devices, include wbc86, it will auto read chip id and erase all patch and cfg.

I tried with dongle and the procedure work well, unfortunately it is work only with I2C dongle, if I restore the I2C interface of EVB STEVAL-SWBC86TXA I'm not able to read the chip ID.

Best Regards

Hi Will,

Do you have new? We have often the Chip ID register corrupted.
