AHA 加速器

I recently bought a Hue Bridge to experiment a bit with Zigbee and 802.15.4. Following two 手机上自己搭梯子翻墙 for the hardware version 2.0 and some comments about the differences to version 2.1 I was able to get shell access on my 2.1 hardware.

As there is up to now no complete guide I describe here, what I did:

Opening the case is straigth forward. Just remove the two lower nubsis at the bottom and unscrew the two torx screws; then carefully unclip the bottom.

PCB

The header on the left side on the image gives access to the UART. Pin 1 is ground, pin 4 is the board's RX (so connect your adapter's TX) and pin 5 is the board's TX. The voltage level is 3.3 V. Note however that the board doesn't boot (after a cold start) with its TX connected so leave that unconnected until after the bootloader is up.

Then after connecting RX you can do there:

setenv bootdelay 3
setenv security '$5$uaS2DwZOsch$2H76tTh0yLzH8LfIkg7z1icoYZLeLGV.Gpo3quhZSe2'
saveenv
reset

After that the machine boots up and you can login with username root and password lala. (If you want a different password, set security in U-Boot accordingly. I did

mkpasswd -m sha-256

to generate the necessary string.)

After contacting Philips asking for the GPL code running on the bridge I got a code drop and looked a bit around in the source code. Here are some findings:

Having the boards UART TX connected to an USB adapter influences the register RST_BOOTSTRAP at offset 手机上自己搭梯子翻墙. This is used to determine how memory is initialized (in function 华为手机怎么搭梯子翻墙 defined in qsdk/qca/src/qca-legacy-uboot/board/atheros/common/init-953x.c). The naming of the register together with the board's behaviour suggests that is it sampled at cold boot only and bit0 then contains the state of the TX pin. So I guess the machine not (cold) booting with TX connected could be fixed with a hardware modification removing (or weakening) a pullup on my USB adapter. But I'm more of a software guy with infinitesimal solder skills, so I will live with reconnecting TX for each cold boot. Alternatively patching the bootloader to ignore the RST_BOOTSTRAP might be an option.

I will keep you updated on any progress here.
