Hi, I would like to pass a rootfs.squashfs image to linux with the initrd in the bootargs parameter, but I can only get it to work by including the size of the image (e.g. ",21M"). Is there a way to make this work without hardcoding the size of the image in u-boot?
This is my current configuration:
/set bootargs 'console=ttymxc0,115200 root=/dev/ram0 ro initrd=0x83800000,21M rootfstype=squashfs' bootz 0x80800000 - 0x83000000/
During production, the rootfs.squashfs image is transferred to RAM without involving u-boot, so u-boot does not know the size of the image. The tool loading the image into RAM obviously know the size, but I do not have a shell into u-boot, so there is no easy way to tell u-boot.
I have considered prepending the size of the image, to the image it self, and have u-boot extract it from RAM. However, I'm wondering if there is a better method?
