Re: [microblaze-uclinux] Setting up framebuffer
Hi all,
I am experiencings some problems with the framebuffer and now I am
trying to debug the kernel in order to figure out what is going wrong.
I have seen this post from Simon Tam and I saw that there is many
information in the bootlog concerning the framebuffer. I do not get
this information when I boot my board. Is there any option in
menuconfig to show it or should I add 'printk' manually?
Thanks a lot. Kind regards.

Hi,
I am still having problem with my frame buffer driver and
have some configuration questioins. Attached is bootlog. As far as I
can tell, my fb driver has been registered correctly during bootup. I
can see the correct physical address put in the structure. I have the
frame buffer console enabled also. However I don¢t see anything on the
display.
One of the Linux documents says tty0 can not be used with
fb devices. And it seems the first virtual console tty1 should be use
instead. Is this correct? If yes I wonder that is the cause of my
problem. Although I have the tty1 node in /dev, I can only see vtcon0
under /sys/class/vtconsole. I believe normally I should see vtcon0 all
the way to vtcon63, correct? If yes why don¢t I have other vtcons?
Please let me know what I am missing here. I have been struggling with
this for a while and really like to get some help.
Thanks,
Simon
