printing the meraki_loadaddr yields 800000, so it didn't get messed up. There's something wrong with the commands in the toh.
I did these commands from another thread (linked below).
`setenv serverpath; setenv netloadmethod tftpboot; setenv bootargs
console=ttyS0,${baudrate} rootfstype=squashfs mtdoops.mtddev=oops; run
meraki_load_net meraki_checkpart meraki_bootlinux`

Then I connected the WAN port and used wget to pull the latest image
http://downloads.openwrt.org/snapshots/targets/apm821xx/nand/openwrt-apm821xx-nand-meraki_mx60-squashfs-sysupgrade.bin
and used
sysupgrade <image>.binselected NO for keep config, upon reboot everything is happy as a clam.
I was NOT able to get a recovery partition built as I couldn't decipher how to mess with UBI without bricking the board_config.
Thanks for the reply.
