Boot stock firmware while no USB/IDE present for Pogoplug V3 OXNAS (no replies)

Hi,

I tried to modify the Uboot env settings to try to boot from USB or IDE first,
if both are not present, then boot from the internal flash/stock firmware.

bootcmd=run bootcmd_uenv; run dt_bootcmd_usb; run bootcmd_stock; reset

the complete system configration:

Stock Pogoplug OS:

 U-Boot (1.1.2 Jul 29 2010)

cat /proc/mtd0

mtd0: 08000000 00020000 "NAND 128MiB 3,3V 8-bit"
mtd1: 00e00000 00020000 "boot"
mtd2: 07200000 00020000 "rootfs

U-boot 2013.10 install per instructions here

however while no usb/ide present, it will try to reboot instead of boot the internal stock firmware:

I can stop the booting process and have it boot to stock firmware via running
run bootcmd_stock

what should I change here to have it auto boot the stock firmware if no usb/ide present?

Thanks in adavance
