Hello everyone,
Sorry for the Google translation!
I have a problem with my tinker; the protective cover of the SD card is broken which makes my tinker normally unusable :-(
Would it be possible to put an OS on a USB key and have my tinker booted on it please?
Thank you for your help!
No, you must have the u-boot loaded from SD or eMMC (if you have S version of TB). I don't know differently where the bootloader might reside.
Definitely is impossible on the internal MCU flash, which has already its own management that won't allow spare space to load a BIOS.

It may take some tackling to solder a SD card adapter to SD micro, to fix your problem.
Light blue words might be a link. Have you try to click on them? Big Grin
It's also technically possible to boot from SPI, with some work:

Probably easier to fix the SD card holder though.
As far as I know, it is always necessary to have a SD for initiate the boot protocol!

Try this:

U-boot still have to be on SD or eMMC.

You will get poor I/O performance.

Did you test on current build?
Armbian. Lightweight Debian Stretch or Ubuntu Bionic for Tinker Board.
