The frame buffer driver is being debugged by Chirag. Once that is ready, we should have full lvds lcd support on the i.mx6 platform. On Jun 12, 2014 2:45 PM, "Stefan Kalkowski" < stefan.kalkowski@...1...> wrote:

Hello Mahe,
You can see that the console output gives a lot of hints as to whether it is the expected output. For starters, the abort call: the kernel has stopped. Right before that stage, nitpicker says "No route to service "Framebuffer"' and rightly so. There's no framebuffer driver running for i.mx6 and secondly, you might not have connected any display for it to even work.
just for clarification: the kernel didn't stopped at all. It is "nitpicker", the windowmanager, that tried to get a session to the framebuffer driver. As there is no such driver available, when asking its parent process, "nitpicker" got a "Service_denied" exception in return. The "nitpicker" initialization code doesn't catched that exception, that's why c++ exception handling code printed the uncaught exception name and called the abort routine. Therefore, it's not the kernel, but nitpicker that stopped.
Regards Stefan
The demo scenario is a behemoth for initial development with the board. As I'd mentioned in the wiki, try exploring simple scripts like run/printf, run/nested_init to get a feel for the build process.
Cheers Aditya

Hello , Thanks for your help . I did the steps given in the wiki. We cloned the repos then created the build directory and We compiled using RUN_OPT="--target uboot" make run/demo Then we copied the image from the build/var/run/demo/uImage into the SD card. After that we connected the board and worked on the followingcommands.
u-boot> mmc dev 1 u-boot> fatload mmc 1:1 0x10800000 uImage u-boot> bootm 10800000 We are getting the following message.

wheather is the expected output? Thanks
