Hello everybody,
I am using Arch Linux ARM on a Cubietruck. My distribution packages the most
current linux-sunxi kernel from here: https://github.com/linux-sunxi/linux-sunxi
for usage on both Cubieboard 2 and Cubietruck.
I now experienced a problem regarding kernel configuration.
Cubietruck seems to need all of FB_SUNXI = y like this:
CONFIG_FB_SUNXI=y
CONFIG_FB_SUNXI_RESERVED_MEM=y
CONFIG_FB_SUNXI_UMP=y
CONFIG_FB_SUNXI_LCD=y
CONFIG_FB_SUNXI_HDMI=y
in order for display output (both VGA & HDMI) to work at all. I couldn't get
display output to work if these settings were partially or completely set to
module.
However, according to user reports the Cubieboard 2 stops working if
CONFIG_FB_SUNXI_LCD gets statically built into the kernel.
("The LCD driver built in is causing a kernel oops and halting the board.")
You can also see this issue here:
https://github.com/archlinuxarm/PKGBUILDs/issues/767
I can't test or examine this issue myself as I don't own a Cubieboard 2.
I reported this issue with my distribution
(https://github.com/archlinuxarm/PKGBUILDs/issues/775) and they told me it
won't be possible until the blocking LCD driver issue with Cubieboard 2 was
fixed upstream, so that's why I'm taking this to you in hope for help.
Many thanks in advance!
Fabian
