AIR-AP2802I-E-K9 displays preboot hw-selection menu

[haenselma]

One of our 2802 APs does not boot correctly. Connecting to the console after powering on, a preboot hw selection menu is displayed. After typing the correct number (2) the AP boots up. How can I disable the menu?

Output:

If you can get the AP into u-boot, post the complete output to the following command: 

prish

Sorry there is no prish command in u-boot. Maybe printenv is similar?

FACTORY_RESET=2

I think this is the reason why.
Correct this by doing the following:

setenv FACTORY_RESET 0
saveenv
boot

If the above steps still does not resolve the issue, force the AP into u-boot again and enter the following u-boot command:<

progpid 2k

[haenselma]

I don't know why but I also can't use progpid.
My masterboot version is 1.34. this is different to the other ap's 1.24.
All commands I find in u-boot with p are:
u-boot>> p
pci pciePhyRead pciePhyWrite phyRead phyWrite phy_fw_down_to_ram
phy_fw_down_to_spi phy_type ping printenv prog_emblacklist prog_emcookie
prog_emeeprom prog_emignore prog_emserial prog_emwhitelist prog_flags
