Here are my commands to setup the u-boot environment:

setenv menu_1 Boot from microSD (partition 2): setenv bootargs 
\${bootargs_base} rootfstype=ext2 root=/dev/mmcblk0p2 rootdelay=5 
\${mtdparts} ro\; mmcinit\; ext2load mmc 0:2 0x32000000 /boot/uImage\; 
bootm 0x32000000
setenv menu_2 Boot from microSD (partition 3): setenv bootargs 
\${bootargs_base} rootfstype=ext2 root=/dev/mmcblk0p3 rootdelay=5 
\${mtdparts} ro\; mmcinit\; ext2load mmc 0:3 0x32000000 
/boot/uImage.bin\; bootm 0x32000000
setenv menu_3 Boot from microSD (partition 4): setenv bootargs 
\${bootargs_base} rootfstype=ext2 root=/dev/mmcblk0p4 rootdelay=5 
\${mtdparts} ro\; mmcinit\; ext2load mmc 0:4 0x32000000 
/boot/uImage.bin\; bootm 0x32000000

Right now, you are able to boot from your partitions 1, 2, 3 and 6 ?

I will reformat my fat partition into ext2 and test again.
