RPi Pidora 20 TFT driver

Linux-haladó

Üdv!

Ez alapján próbálom a TFT kijelzőt meghajtani:
https://sites.google.com/site/davidemadrisan/linux-embedded/pidora#TOC-…

A "make menuconfig"-ban beállítottam amit írt, el is mentette a .config fájlba.
A "make M=drivers/video/fbtft" parancsra ennyit ír:
Building modules, stage 2.
MODPOST 0 modules

A .ko modulok nem is jöttek létre persze. Mit hibáztam el?

Jómagam egy adafruitos distribből szedtem ki a .config-ot,majd azzal forgattam kernelt. De nem indult el..
A téma meredek.

---
--- A gond akkor van, ha látszólag minden működik. ---
---

Az Raspbian OS-re (Debian) vonatkozik és azon nem működik a cx231xx driver (nekem erre volna szükségem).
Pidora (Fedora) alatt úgy tűnik működik a cx231xx, viszont a TFT driver is kellene. :)

De oykawa segítségével próbálunk majd egy 3.18-as kernelt. Beszámolok majd az eredményekről. Ha minden igaz, akkor ez működik majd Pidora és Raspbian OS-eken is. De tesztelem majd ezeket!

Ezzel a kernellel (config) próbáltam: http://pastebin.com/u5DnfgtE

Van valakinek ötlete, mi lehet a bibi?
A TFT-n ILI9341 van írva. Melyik paraméter húzza be ezt a drivert?

Sajna raspbian alatt is ugyanaz a hiba: failed -517
