Fernvale

Fernvale is an open-source development platform for the Mediatek MT6260. It was also specifically designed for reverse engineering.

It is available on the sysmocom web-shop

Software

  • There is a simple bootloader/interactive shell called fernly
  • There is a downstream port to Nuttx which is bootable but provides limited features
  • There is a downstream OsmocomBB port which has a bootable layer1 image that doesn't support any of the GSM hardware yet.

Progress

Apr 22 2018 - layer1 firmware has stubbed out implementations for mediatek/fernvale. layer1/main blinks the big LED on fernvale and fernly usb serial is ported so that debug messages are possible. See my mtk-layer1 branch on github.

Feb 13 2018 - fixed up Makefile.mtk so that both SciphoneDreamG2 and Fernvale firmwares build. An LED blink firmware is working on Fernvale but the loader_mtk firmware no longer seems to work on the SciphoneDreamG2.

TODOs

  • port Layer1bin - unrznbl is working on this currently
  • create library from osmocom-bb to be used in NuttX layer1 app (hopefully very little copying of code into nuttx tree)
  • port Mobile to NuttX

Help welcome

Very few people are working on it1, and because of that progress have been very slow.

1 See This blog post for more background on the issue.
