u-boot not working with multiple partitions on SD Card

Hi,

I created 2 exact partitions with the same kernel, and rootfs, which I built as per eee wiki for beaglebone black. I am currently unable to move to the second partition.

Here is my partition layout:
root@arm:/home/ubuntu# fdisk -l
Disk /dev/mmcblk0: 7.22 GiB, 7744782336 bytes, 15126528 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xfb2889fe

Device Boot Start End Sectors Size Id Type
/dev/mmcblk0p1 8192 7462912 7454721 3.6G 83 Linux
/dev/mmcblk0p2 7462913 15126527 7663615 3.7G 83 Linux

Disk /dev/mmcblk1: 3.58 GiB, 3825205248 bytes, 7471104 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x9c2c8b97

Device Boot Start End Sectors Size Id Type
/dev/mmcblk1p1 * 8192 7471103 7462912 3.6G 83 Linux

In the above, /dev/mmcblk0p1 and /dev/mmcblk0p2 are the ones that are created by me.

However, when I tried to move to the 2nd partition in u-boot command-line I could not : It failed with an ERROR.

=> mmc dev 0 0
switch to partitions #0, OK
mmc0 is current device
=> mmc dev 0 1
switch to partitions #1, ERROR
=> mmc list
OMAP SD/MMC: 0 (SD)
OMAP SD/MMC: 1 (eMMC)
=> mmc part

Partition Map for MMC device 0 – Partition Type: DOS

2 7462913 7663615 fb2889fe-02 83
=> mmc dev 0 1
switch to partitions #1, ERROR

It’s important to note that I can view both partitions with ext2ls ; its just that u-boot is unable to recognise the second one.

=> ext2ls mmc 0:1 /

Let me know what I am missing
