Hi, I'm not sure if it is my sdcard, my A31 hummingboard device, or something I am doing wrong, but I've been trying to boot an A31 hummingbird from an sdcard using the kernel from the sunxi-next branch at
https://github.com/mripard/linux 33da8d2 - Merge tag 'ib-mfd-regulator-v4.2' into sunxi-next and ran into a problem where the kernel would hang while waiting for the root device /dev/mmcblk0p2 If I use the sun6i-a31-hummingbird.dtb built from the linux mainline the sdcard will boot the root file system correctly, but if I use the sun6i-a31-hummingbird.dtb from sunxi-next the kernel will hang while waiting for /dev/mmcblk0p2. I ran a git bisect and narrowed down the commit that causes the problem I am seeing to commit bab03561224baa536b98f1d137d2b6b5dd159763 Date: Tue Mar 10 19:59:21 2015 +0800 ARM: dts: sun6i: hummingbird: Add AXP221 regulator nodes This patch adds the AXP221 regulators. Only the ones directly used on the board are added. Please let me know if there is anything I can do to help fix this problem, if it really is a problem. I have an A31 hummingbird available for testing. Thank you. Lawrence -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
