can you please give me the command line in detail with an example possibly with apalis imx6
Find the mount point of your SD/uSD card by e.g. using df or lsblk:
[user@host ~]$ df
Filesystem 1K-blocks Used Available Use% Mounted on
...
/dev/mmcblk0p1 7582228 2808272 4773956 38% /media/user
[user@host ~]$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
...
mmcblk0 179:0 0 7.3G 0 disk
└─mmcblk0p1 179:1 0 7.3G 0 part /media/user
Run the update.sh script with the -o argument pointing to the mount point of the SD card. For example assuming the SD card is mounted at /media/user:
./update.sh -o /media/user/
At this point the SD/uSD card should contain U-Boot, the flash scripts and the root file system image.
