Fernvale¶
Fernvale is an open-source development platform for the Mediatek MT6260.
It is available on the sysmocom web-shop
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
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.
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.
