<castiel652>
yeah I saw the reported issue butI don't have uart available right now
<Namidairo>
luckily uart are clearly marked out on that board and it's not too cumbersome to move the board around with the antennas still attached to solder the headers

Lechu: on what device are you working?
<Lechu>
mrkiko: Ruckus Zoneflex 7372
<mrkiko>
Lechu: thanks! Great!
<mrkiko>
Lechu: is the device heavily locked down?
<Lechu>
Not really, there is an exploit involving "!v54!" command to gain root shell, but not much information is available there.

Lechu: thanks; I did apreciate your work a lot on the ZTE devices as well, but the prospect of having to solder an UART did hold me back from trying them out
<Lechu>
I have yet to figure out, how active/backup image switching is done, and probably patch the ruckus_fw_header tool a bit, and that dreaded power LED which behaves strangely.
<mrkiko>
Lechu: :) :)
<Lechu>
regarding soldering in UART, I prefer to just stick in some male Dupont wires into the pads. If you're lucky, the pads won't have solder in them, then it's a matter of holding them in place ;-]
<mrkiko>
Lechu: :) :) well, considering I am blind, I usually search for someone to help me in soldering matters
<Lechu>
if it's just for single installation I usually don't bother with soldering at all, I'm lazy.
<mrkiko>
Lechu: well, I wanted to try and search the ZTE MF286 - the ipq4xx device variant, don't remember the name
<Lechu>
MF286D it is. Worked on a couple of boards - only one had tinned pads from factory, and yes - cleaning them up was a royal PITA. The board has enormous thermal mass.

The issue with ZF7372 now is that I couldn
<Lechu>
I couldn't find any GPL code, and there is no /dev/mem in stock firmware, nor debugfs, so I couldn't easily extract pinctrl and GPIO mappings, as well as the location of active/backup flag on flash. Changing it from U-boot did not help.
<Lechu>
I even wrote a script to automate figuring out GPIO mapping by iterating over them in sysfs, need to post it somewhere. With that I figured out everything but two power LEDs and one "zone director" LED, which seems to be held high regardless if I set its GPIO low or high.
<PaulFertser>
Wiki already has few scripts to help searching for GPIO-attached LEDs and buttons.
<Lechu>
Buttons are usually much easier, diffing /sys/kernel/debug/gpio in time is the way to go ;-]

<Slimey>
i got all these waps stintel, 2030 and 3040s :P
<Slimey>
pulled from student housing that going to be demolished
<Lechu>
Hah, fixed that godforsaken WLAN LED on MF286 series xD
<Lechu>
It was pinctrl in the end, had to force it to GPIO mode, as usual.
<Lechu>
Also managed to get two more LEDs on ZF7372 working this way, one left to go.
<Lechu>
I wonder if it makes sense to actually replace the GPIO hog with LED and map it to phy0tpt trigger, to do sort-of wired-AND on them, as when the hog is set, the output is controlled by ath10k radio on PCI. What do you think?
<Lechu>
I suspect this was the original intention, however stock firmware just hogged this GPIO, only activity of ath10k was actually shown.
