Troubleshooting • Re: Unable to Activate USB Boot on Zero 2W

Did you remember to reboot from the microSD card after modifying your config.txt file?
I did. I've come at it from several angles, always the result is 3020080a.
The Pi documentation says if the config.txt comment is unsuccessful on several tries then you probably have a hardware issue.


Presumably you are asking because it won't boot?


How are you adapting your usb mass storage device for connection to the micro-usb port on the RPi02W?

Are you using the correct micro-usb port on the RPi02W? (The one to the right, nearest the CSI connector, is power-only and will not work for this purpose.)


You may be concerned over an insignificant detail.

The relevant documentation seems to be here : OTP registers on non-BCM2712 devices - https://www.raspberrypi.com/documentati ... 12-devices

Bit 28: enables USB device booting
Bit 28 is set in in the output from otp_dump you report.



The difference seems to be in Bit 11. That is not documented.
This list contains the publicly available information on the registers. If a register or bit is not defined here, then it is not public.
