"unknown error!" when trying to read/erase NVRAM

[w0lf3h]

I'm getting this "unknown error!" message when attempting to erase or read the NVRAM from my CC2652R usb.
Is there a place where there would be logs or something to show why this would be happening? Thanks!

Same issue with HamGeek CC2652P

OK. I'll try to add logs somewhere.

Just want to chime in and say I'm also having this issue. Happy to assist if you need anything from us.

just for reference: you can restart the process one more time, and it's quite possible that everything will go without errors.

Hi,
I have same issue with SONOFF CC2652P for several months. Please help solve the problem.
And if possible, add correct operation of Auto BSL activation.

For SONOFF Dongle-P:
Maybe serial driver doesnt installed? Check it in device manager.
