when I boot from sd, everithing works, but from USB stick I got this screen:

1. Make boot SD. Make sure it works.
2. Format USB stick.
3. Copy all files from SD to USB stick.
4. Edit cmdline.txt, write "wtboot=usb" instead of "wtboot=mmc".
5. Tell me the reason to boot Pi from USB.

Hi akatik,

thanks, it's working.

idea is, that we will have multiple clients, and employee can sit to any of them, insert own usb with his config, and can work.

or is there any other possibility to boot from sd, and read config from USB?

thank you
