Linux on Mediatek MT6235 Phones.

It’s started. Just give loads of thanks to osmocom-baseband guys who made the initial efforts.
Anyway, the whole stuff is working. Even on my old E1000 phone.
The instructions are pretty much straightforward. Take your phone

Hook it to youe favourite uart to usb chip (mine is ftdi)

And fire up osmocon and osmoload as described here: http://bb.osmocom.org/trac/wiki/SciphoneDreamG2

While now uboot has somewhat working support for nand, ram, mmc
Uncommenting PLL initialisation code makes my device hang in process, so we’re at somewhat really slow.
But nevertheless, here we go

I copied all the sciphone’s code and tagged it e1000_rachel, since all the chineese device differ a little.
Now it’s time to fix some uart bugs, write more code… Hell, I didn’t even think that was possible.
With a 2d accelerator, wifi, bluetooth, full keyboard and TV this thing ca be a hell of thing to control.. say a mikrokopter with analog camera in there?
Possibilities are endless, hardware is dirt cheap.

  1. И тебе не кашлять, к концу недели будет драйвер вода с клавы для линуха =)))

    1. Nope, I sold my mt6235 phone ages ago, swapped it for a more rcent mt6516, then mt6572 one. These have android, so running homebrew stuff is a hell lot easier.
      It didn’t got further poking around some registers. Guys at osmocom might have come up with something better, but I’m not following any more.
