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 -lDisk /dev/mmcblk0: 7.22 GiB, 7744782336
bytes, 15126528 sectorsUnits: sectors of 1 * 512 = 512 bytesSector size
(logical/physical): 512 bytes / 512 bytesI/O size (minimum/optimal): 512
bytes / 512 bytesDisklabel type: dosDisk identifier: 0xfb2889feDevice
Boot Start End Sectors Size Id Type/dev/mmcblk0p1 8192
7462912 7454721 3.6G 83 Linux/dev/mmcblk0p2 7462913 15126527 7663615
3.7G 83 LinuxDisk /dev/mmcblk1: 3.58 GiB, 3825205248 bytes, 7471104
sectorsUnits: sectors of 1 * 512 = 512 bytesSector size (logical/physical):
512 bytes / 512 bytesI/O size (minimum/optimal): 512 bytes / 512
bytesDisklabel type: dosDisk identifier: 0x9c2c8b97Device 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 0switch to partitions #0, OKmmc0 is current device=> mmc
dev 0 1switch to partitions #1, ERROR=> mmc listOMAP SD/MMC: 0 (SD)OMAP

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.

Let me know what I am missing
