Hello

I am a student in the Technical University of Sofia and my final project involves writing custom software to the TLSR8355 chip.
I have written wrong firmware to this chip and I don't know how to reprogram it over USB. I've read there is an ISP feature in the datasheet...
Even better - are there any Reference Guide/Datasheet that provide detailed description of how the usb registers work.

Best regards
Alex

In BDT, select chip B85​ (covers TLSR8355), then click SWS → Erase → Download.

If the chip is in sleep/deep-sleep, use Activate​ before downloading.
