Can't boot off SD card. ignoring bootargs

I'm trying to get my plug to boot off a SD card. I'm setting the bootargs correctly but it still boots off of NAND: I know this because the SD card currently in the plug has nothiing on it. I think I may have an updated uboot since after I did a recovery, I no longer have a bootargs setting, so makes sense that it is not longer used

The uboot env has

standalone=fsload 0x2000000 $(image_name);setenv bootargs $(console) root=/dev/mtdblock0 rw ip=$(ipaddr):$(serverip)$(bootargs_end)

which specifies /dev/mtdblock0

Here's what happens when I try to boot of the SD:

Marvell>> setenv bootargs console=ttyS0,115200 root=/dev/mmcblk0p1 rw ip=10.4.50.4:10.4.50.5:10.4.50.5:255.255.255.0:DB88FXX81:eth0:none
