I am trying to boot into an image using the following commands:
setenv bootcmd "load mmc 1 0x82000000 swupdate-image-imx6ull14x14evk-20230206204748.rootfs.ext4.gz.u-boot;load mmc 1 0x82a00000 imx6ull-14x14-evk.dtb;load mmc 1 0x83000000 zImage;setenv root /dev/ram0;setenv rootfstype ext4;bootz 0x83000000 - 0x82a00000"
saveenv
print bootcmd
run bootcmd
This starts a kernel, finds and image and attempts to run it. However my issue is
[ 2.921973] VFS: Cannot open root device "(null)" or unknown-block(0,0): error -6

I cannot seem to properly set the root= parameter. I have tried setting it in and out of my bootcmd. I am not 100% of my syntax but I cannot find an example to say I am wrong. Can anyone point me to my mistake?
The kernel command line is defined by the environment variable bootargs.
