hi,
Iam trying to get 2.6.34-x2 linux kernel up on omapevm mistral board,
while booting the kernel i get
1.373901] omapfb omapfb: no displays
[ 1.377685] omapfb omapfb: failed to setup omapfb
[ 1.382568] omapfb: probe of omapfb failed with error -22

is there something that i am missing while configuring the kernel.
thanks in advance.

Nope, it's just not supported... I don't have an omapevm laying
around so i can't fix it..

Give the 2.6.35 image a try, as upstream might have already fixed the issue..

v2.6.35.1-d15

[Hiremath, Vaibhav] Is there any reason why you are using 2.6.34-rc? No display means either, displays are not enabled in your config file or your board file is not having platform hook up for DSS which defines displays.

I would suggest you to migrate it to 2.6.35 where it is working without any issues.

Thanks,
Vaibhav

hi,
Thanx for the replies.
anyways i was able to fix the omapfb omapfb: no display by applying
the patch given in the following link.
https://patchwork.kernel.org/patch/85197/
people facing similar issues on Omap evm boards can use the same.

I tried using 2.6.35 but faced the similar issue while using
OMAP3_EVM_DECONFIG. may be vdds_dsi REGULATOR_SUPPLY patch is still
not taken in.
