Hi,
I am using an OLinuXino A20 LIME with arm.
boot.scr used to have the following content (I removed the initial
non-readable characters) which let boot the device without issues:
> setenv mmcpart 1
>
> setenv mmcroot /dev/mmcblk0p2 ro
> setenv mmcrootfstype btrfs rootwait fixrtc
> setenv mmcrootflags subvol=@

> setenv initrd_file initrd.img-4.8.0-2-armmp-lpae
> setenv fdtfile sun7i-a20-olinuxino-lime.dtb

> setenv loadfdt load mmc ${mmcdev}:${mmcpart} ${fdtaddr} /dtbs/${fdtfile}
>
> setenv loadfiles run loadkernel\; run loadinitrd\; run loadfdt
> setenv mmcargs setenv bootargs console=${console} root=${mmcroot}
> rootfstype=${mmcrootfstype} rootflags=${mmcrootflags}
>
> run loadfiles; run mmcargs; bootz ${loadaddr} ${initrd_addr}:${initrd_size}
> ${fdtaddr}
The new content of that file is:

Which does not allow the device to boot.
None of the variables in that script is set in the current environment.
As work-around I am currently copying a saved version of the former file
content to boot.scr.
How can I make the new file work?
Thanks
