Hello everyone, I am using Arch Linux ARM on a Cubietruck. My distribution packages the most current linux-sunxi kernel for use with both Cubieboard 2 and Cubietruck.
However, I now stumbled upon a kernel configuration problem with the two boards. Cubietruck display output does only seem to work when *all* of FB_SUNXI are statically compiled into the kernel 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 Neither VGA nor HDMI work if one of these is set to build as module, regardless of module loading order in modprobe.conf.d, etc. However, if CONFIG_FB_SUNXI_LCD=y is set in kernel config, the Cubieboard 2 seems to refuse to boot as the LCD driver causes a kernel oops. Unfortunately, I can't provide additional information about this LCD driver problem, as I don't own a Cubieboard 2 myself. I took the issue to my distribution, but they told me that it won't be possible to integrate the needed kernel configuration changes for Cubietruck display as long as the blocking issue with the LCD driver isn't fixed for Cubieboard 2 and that this would be needed to be fixed upstream. You can see relevant issues here: https://github.com/archlinuxarm/PKGBUILDs/issues/767 https://github.com/archlinuxarm/PKGBUILDs/commit/9dffd3a07a143e056d66a4f2635c9d26a6e777ab https://github.com/archlinuxarm/PKGBUILDs/issues/775 Help would be greatly appreciated - many thanks in advance!
