Hey, I have tried booting linux image in the eMMC through u-boot but it
always drops to busybox shell. As suggested by the busybox shell I double
checked the PARTUUID using blkid it's a match so why can't it load the rfs?
My emmc has a single partition debian image. U-boot lies in the first
partiition of my sd card(boot by pressing s2 switch.Here are my
logs,uEnv.txt.
Standalone beaglebone boots just fine that is without my u-boot and sd card
not inserted it boots fine from the emmc(which means emmc image is good)
just when I try uboot from sd card this happensEnter code here

Gave up waiting for root file system device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Missing modules (cat /proc/modules; ls /dev)
