Aruba AP-105

The Aruba AP-105 is a small Atheros based AP that has 2x wireless chips for 2.4GHz and 5GHz operation. It is a PoE AP that normally requires the use of a wireless controller device. Surprisingly, this device packs a 16MiB SPI flash chip as well as 128MiB of RAM.

Install OpenWrt (generic explanation)

  1. → Install OpenWrt >22.03.5
  2. Obtain U-Boot <22.03.5
  3. → Install U-Boot <22.03.5
  4. → Install OpenWrt <22.03.5

Since the release of Openwrt 22.03.5 isn't required anymore to replace the bootloader with U-boot. The following installation instructions

1. Attach to the serial console of the AP-105. Interrupt autoboot and change the U-Boot env.

 $ setenv apb_rb_openwrt "setenv ipaddr 192.168.1.1;
   setenv serverip 192.168.1.66;
   netget 0x84000000 ap105.bin; go 0x84000040"
 $ setenv apb_fb_openwrt "cp.b 0xbf040000 0x84000000 0x10000;
   go 0x84000040"
 $ setenv bootcmd "run apb_fb_openwrt"
 $ saveenv

2. Load the OpenWrt initramfs image on the device using TFTP. Place the initramfs image as “ap105.bin” in the TFTP server root directory, connect it to the AP and make the server reachable at 192.168.1.66/24.

$ run apb_rb_openwrt

3. Once OpenWrt booted, transfer the sysupgrade image to the device using scp and use sysupgrade to install the firmware.

The other steps below are not needed anymore

Note that the stock bootloader on this device does not allow for unsigned kernels to boot, so replacing the bootloader is required for OpenWrt support on this device. Sadly at this time the only way to do this is via directly writing to the SPI Flash. The custom U-Boot for this device can be downloaded from https://github.com/chunkeey/u-boot-ap105/releases and extracted from the latest release .tar.gz file.

It is HIGHLY recommend that before doing anything, you take a full backup of the SPI Flash.

To flash the SPI NOR, a 16 pin Test Clip is recommended. One such example is the Pomona Electronics 5252. Note you will need to manually wire up said test clip to a flashing tool or device, such as a Raspberry Pi.

Generic Process

If you are not using flashrom, then you will need to do the following with whatever tool you are using:

  1. Create a full dump of the SPI Flash, and store it in a safe place
  2. Erase and Clear 0x0-0x3ffff on the SPI Flash
  3. Flash U-Boot to 0x0
  4. Proceed to the OpenWrt Install Procedure

Flashrom Process

If you prefer to have a walkthrough guide of doing this with flashrom, please follow the below steps:

Note that the below install steps assumes a few things:

  • That you are using flashrom to read/write to the SPI flash
  • That your SPI reader is a linux SPI Dev (ex, a Raspberry Pi wired to the SPI Flash)

1. Create a full dump of the SPI Flash, and store it in a safe place

flashrom -r AP105-stock-SPI-dump.rom -p linux_spi:dev=/dev/spidev0.0,spispeed=16500 -c MX25L12835F/MX25L12845E/MX25L12865E

2. Create a copy of your SPI Flash dump for us to modify

cp ./AP105-stock-SPI-dump.rom ./custom-dump.rom

3. Erase the stock bootloader from the start of the image

dd if=/dev/zero bs=256K count=1 | tr "\000" "\377" | dd of=custom-dump.rom conv=notrunc

4. Apply u-Boot to the image

dd if=u-boot.bin of=custom-dump.rom conv=notrunc

5. Flash the new modified image back to the device

flashrom -w custom-dump.rom -p linux_spi:dev=/dev/spidev0.0,spispeed=16500 -c MX25L12835F/MX25L12845E/MX25L12865E

Note that installing OpenWrt requires that you have installed the custom U-Boot first.

  1. Wire up the Aruba AP-105 to an Ethernet port on your computer, and set that port to a static IP of 192.168.1.101
  2. Start a TFTP server on your computer, and in your tftp root copy your OpenWrt sysupgrade.bin file to firmware.bin
  3. Power on the AP-105, and hold the reset button on the back. Continue to hold it until you see both wireless LEDs blink red.
  4. At this point, the AP will download and install OpenWrt. Watch the console to confirm OpenWrt has been flashed then reboot. If you do not have console access, wait 5 minutes before power cycling the device.
  5. You should now have OpenWrt installed on the device!

Thanks to the custom U-Boot, the reset button can be used to tftpload a new firmware to the device at anytime. To do so, set your computer to a static IP of 192.168.1.101 and wire it directly to the access point. While the access point powers on, hold the reset button until you see the WLAN LEDs both flash red. At this point, U-Boot will attempt to tftpload a file named firmware.bin and flash it to the device. This can be useful for recovering a corrupt upgrade/install.

As long as you have a full SPI Flash backup available, you can install it back to your device at anytime through U-Boot. To do this, setup your local computer with a Static IP of 192.168.1.101 and a tftpserver. Next, place a copy of your SPI backup in the root of your tftp server and rename it ap-105-stock.bin. Now power on your AP-105 and with a console cable, interrupt boot to access the u-boot shell. Once here, run the following command to revert back to the Stock Firmware:

run loadStock; reset;

The default network configuration is:

Interface Name Description Default configuration
br-lan LAN 192.168.1.1/24
wl0 WiFi Disabled
wl1 WiFi Disabled

Note that to configure this device as an AP, you will want to configure br-lan to be either static, or a DHCP client. You may also want to consider using a VLAN for WAN connectivity if you plan to run NAT/DHCP.
