The Aruba AP-303 is a 2×2 802.11ac Wave 2 access point. It is fairly powerful with a quad-core ARM processor and 512 MB of memory.

1. Get the OpenWrt initramfs image. Rename it to ipq40xx.ari and put it into the TFTP server root directory. Configure the TFTP server to be reachable at 192.168.1.75/24. Connect the machine running the TFTP server to the ethernet port of the access point.
2. Connect to the serial console. Interrupt autobooting by pressing Enter when prompted.
3. Configure the bootargs and bootcmd for OpenWrt
   

      $ setenv bootargs_openwrt "setenv bootargs console=ttyMSM1,9600n8"
      $ setenv nandboot_openwrt "run bootargs_openwrt; ubi part aos1; ubi read 0x85000000 kernel; set fdt_high 0x87000000; bootm 0x85000000"
      $ setenv ramboot_openwrt "run bootargs_openwrt; setenv ipaddr 192.168.1.105; setenv serverip 192.168.1.75; netget; set fdt_high 0x87000000; bootm"
      $ setenv bootcmd "run nandboot_openwrt"
      $ saveenv

4. Load OpenWrt into RAM
   

   $ run ramboot_openwrt

5. After OpenWrt booted, transfer the OpenWrt sysupgrade image to the /tmp folder on the device.
6. Flash OpenWrt
   

   $ ubidetach -p /dev/mtd1
   $ ubiformat /dev/mtd1
   $ sysupgrade -n /tmp/openwrt-sysupgrade.bin

→ generic.sysupgrade

→ generic.debrick

→ failsafe_and_factory_reset

→ Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

→ hardware.button on howto use and configure the hardware button(s). Here, we merely name the buttons, so we can use them in the above Howto.

The Aruba AP-303 has the following buttons:

Front:
Insert photo of front of the casing

Back:
Insert photo of back of the casing

Backside label:
Insert photo of backside label

Note: This will void your warranty!

Remove the 4 screwas on the back of the device. The metal casing can be lift up. The PCB is secured with a single screw in the middle of the PCB.

→ port.serial general information about the serial port, serial port cable, etc.

To connect to the serial console, you can solder to the labled pads next to the USB port or use your Aruba supplied UART adapter.

Do NOT plug a standard USB cable into the Console labled USB-port! Aruba/HPE simply put UART on the micro-USB pins. You can solder yourself an adapter cable:

VCC - NC D+ - TX D- - RX GND - GND

The console setting in bootloader and OS is 9600 8N1. Voltage level is 3.3V.

To enable a full list of commands in the U-Boot “help” command, execute the literal “diag” command.

None so far.
