how to make u-boot to load rootfs from 2nd partition of sd card?
I am trying to make u-boot to load rootfs from sd cards second partition while loading kernel and device tree from the first partition. Has anyone faced this situation before?
I've set the bootargs as shown below but it didn't work.
printenv bootargs
bootargs=console=ttyS0,115200 root=/dev/mmcblk0p2 rootwait
here are the logs:

OP answered his own question in the comments. As another user pointed out, that text is garbled. OP could provide the formatted text either by 1) editing his OP or 2) posting an answer to his own question. In the meantime I provide the formatted text below. This text helped me to progress on a similar problem that I am facing so I post it here in case someone else finds it useful.
setenv mmc_rootpart 2 part uuid mmc ${mmc_bootdev}:${mmc_rootpart} uuid
setenv loadkernel load mmc 0:1 ${kernel_addr_r} boot/zImage
setenv loaddtb load mmc 0:1 ${fdt_addr_r} boot/${fdtfile}
setenv bootargs rootwait root=/dev/mmcblk0p2 rw 8152.mac_address=fe:81:1a:11:21:1c vt.global_cursor_default=0 console=ttyS1,115200 loglevel=8
setenv bootcmd run loadkernel \&\& run loaddtb \&\& bootz ${kernel_addr_r} - ${fdt_addr_r}

The issue is that per your logs:
[ 0.000000] Kernel command line: rootwait root=PARTUUID=a545119e-01 rw r8152.mac_address=fe:81:1a:11:21:1c vt.global_cursor_default=0 console=ttyS1,115200 loglevel=8
What you set as bootargs are not being kept, or used. So you need to look at and modify the boot.scr that you're using and so in turn whatever Linux distribution that you're using.
