| 3 | 16 | gnutoo | Fernvale is an open-source development platform for the Mediatek MT6260. |
| 4 | 1 | craig_comstock | |
| 5 | 15 | gnutoo | It is available on the "sysmocom web-shop":http://shop.sysmocom.de/products/fernvale-mt6260-reverse-engineering-development-kit-dvt2 |

| 8 | |||
| 9 | * There is a simple bootloader/interactive shell called "fernly":https://github.com/xobs/fernly/ |
||
| 10 | * There is a downstream "port to Nuttx":https://github.com/sutajiokousagi/fernvale-nuttx which is bootable but provides limited features |
||
| 11 | * There is a downstream "OsmocomBB port":https://github.com/unrznbl/osmocom-bb/tree/mtk-layer1 which has a bootable layer1 image that doesn't support any of the GSM hardware yet. |

| 27 | h2. Progress |
||
| 28 | |||
| 29 | 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":https://github.com/unrznbl/osmocom-bb/tree/mtk-layer1 on github. |
||
| 30 | |||
| 31 | 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]]. |
||
| 32 | |||
| 33 | h2. TODOs |
||
| 34 | |||
| 35 | * port [[Layer1bin]] - "unrznbl":https://github.com/unrznbl is working on this currently |
||
| 36 | * create library from osmocom-bb to be used in NuttX layer1 app (hopefully very little copying of code into nuttx tree) |
||
| 37 | * port [[Mobile]] to NuttX |
||
| 38 | 3 | gnutoo | |
| 39 | 38 | gnutoo | h2. Help welcome |
| 40 | |||
| 41 | Very few people are working on it, and because of that progress have been very slow. |
||
| 42 | |||
| 43 | fn1. See "This blog post":http://laforge.gnumonks.org/blog/20180929-fernvale-discount/ for more background on the issue. |
