Adding Support for Aruba AP135

The device is based on the "Avanta" Marvell 88F6560 SoC (Feroceon core, but using DDR3 and clocked way higher).

The SoC is kwbootable:,78499,116214#msg-116214

User @winnt5 produced this u-boot build for a similar, Avanta-based device:

DSA: It should be compatible with existing Marvell DSA drivers, but the right device tree will need to be crafted for it:,78499,126779#msg-126779

A dump of flash from my AP-135:

Not really. The DSA driver don't work with 88f6560 internal switch yet. I'm using the old mvsw61xx driver in my openwrt. But aruba ap135 uses an external switch, definately compatible with DSA driver.
Please post the output of 'print' and 'help' command in the U-Boot.


aruba ap-135 hardware very nice. suitable hardware for openwrt. let's solve this problem :slight_smile: help me

88F6560 cpu support Aruba AP-135 U-Boot.bin can you share pls

marvell u-boot MX25L12845EMI-10G support file shared pls ? I can't find this image

Installing U-Boot

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 Aruba AP-135 U-Boot.bin 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

Installing OpenWrt

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

  1. Wire up the Aruba AP-135 to an Ethernet port on your computer, and set that port to a static IP of

  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-135, 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!

Sounds basically like the installation instructions for

I don't have any files of this device. You know, I just port openwrt snapshot to f660 and hgg420n. Because I don't have it. You can look here to get source code.

thankyou. I will keep you informed of developments.

It's nice to share information.

Hi ,
Marvell 88F6560 u-boot source code build nor flash pls. Marvell ARMADA SoC family of embedded processors open source platforms I don't know how to compile. Anyone have knowledge on this?

open source tar link shared

Have a look in parent Makefile and trace it to the final build command(s)

I don't know about this. I need help.
