Ar750 not flash. Also, nor?

Can not flash AR750. I go to uboot and I upload and wait 10 minutes. After time, there is one light. I can not connect. I reboot, reboot router. No DHCP.

I do this for NAND and NOR use same file (javascript:getObject(‘firmware/ar750/v1/openwrt-ar750-3.201-0402.bin’) because THERE IS NO EXPLANATIONS FOR FIRMWARES so I don’t know what is correct. But uboot page say NOR is .bin.

Why is AR750 use NOR? Anyway does not work when I upload. Says upload in progress, can close window. I wait 10 minutes, can not DHCP.
