Update the uboot and kernel using USB

I first time use the Toradex module (Colibri iMX6DL 512MB V1.1A),

Currently, the uboot can’t work, I use the recovery mode,

but the article only describe use SD card update the uboot and kernel.

How to use usb cable via any other method update uboot and kernel without use the
SD card and USB drive, my company can’t use the network,so i can’t use the Toradex easy installer.

The second question, how to use the latest uboot update root file system,
I build root file system through buildroot.


Toradex Easy Installer does not require network connection, images can be stored on SD card or a USB drive. Simply download one of the images (https://developer.toradex.com/software/toradex-easy-installer#toradex-embedded-linux-images) and unpack it onto the SD/USB drive.
