Hi, Daniel,
When I print ‘H’ at CONFIG_FRAMEBUFFER_CONSOLE, Isee
CONFIG_FRAMEBUFFER_CONSOLE:
Low-level framebuffer-based console driver.
Symbol: FRAMEBUFFER_CONSOLE [=y]
Type : tristate
Prompt: Framebuffer Console support
Defined at drivers/video/console/Kconfig:90
Depends on: HAS_IOMEM [=y] && VT [=y] && FB [=y]
Location:
-> Device Drivers
-> Graphics support
-> Console display driver support
Selects: CRC32 [=y]
Selected by: DRM_KMS_HELPER [=n] && HAS_IOMEM [=y] && DRM [=n] && !EXPERT
[=y] || DRM_NOUVEAU [=n] && STAGING [=n] && DRM [=n]\
&& PCI [=y] && !EXPERT [=y]
This means, you should turn on HAS_IOMEM, VT(virtual terminal, this may be
missing in your case I guess) and FB(frame buffer, you already have in on).
Hope this helps.

Thanks, Chan. I looked for the framebuffer console support option, but it seems
to be missing from the menus when I run “make menuconfig” using the openrisc
linux repo from Jonas Bonn. Is the framebuffer console menu disabled by some
other option?

Did you turn on the ‘framebuffer console’ in the menuconfig? (device drivers /
graphics support / console display driver support / framebuffer console support)
And you need to press Alt+F2 (or F3, F4,..) to switch to frame buffer console
on the LCD.
Hope this was the case..

Greetings.
I'm playing with orpsocv2 on the Digilent Atlys. I've been following the
excellent orpsocv2 tutorial by Sven Andersson over at
http://www.rte.se/blog/blogg-modesty-corex/using-orpsoc. I've got it working
using u-boot to load applications. I've also got Jonas Bonn's Linux (git clone
git://git.openrisc.net/jonas/linux) booting on my atlys board. It presents a
serial console. Now I'd like to turn on the vga framebuffer driver to output to
the HDMI port on the Atlys board (like Stefan Kristiansson shows
onhttp://www.chokladfabriken.org/projects/orpsoc-atlys/news).
I tried downloading Stefan's Linux repo, but it doesn't seem to have
framebuffer support turned on (e.g., there's no defconfig for atlys, no
atlys.dts with fb0 defined, etc.). I tried manually editing the files and
rerunning "make menuconfig;make" to get framebuffer support, but the resulting
vmlinux still doesn't enable the framebuffer. I still only have serial console
support.
Is there an openrisc linux repo somewhere that has all of the relevant
updates/settings for enabling framebuffer console support on atlys?
Thanks,
Daniel
