If I change to use kernel branch 4.1 for android, then cannot boot:
ARM-TF: https://github.com/96boards/arm-trusted-firmware.git, branch: hikey U-BOOT: git://git.denx.de/u-boot.git KERNEL: https://github.com/96boards-hikey/linux; branch: android-hikey-linaro-4.1
When jump from uboot to kernel, there have no output. I also checked has enabled earlycon. So Amit, John, do you have any suggestion for this?
Hrm. I never did try booting hikey with uboot, so I don't have much to suggest.
As far as general suggestions, I'd probably try to focus on debugging w/ Guodong's currently 4.4 based mainline-rebase branch so you're closer to the upstream tree.
Oops. Sorry. Still drinking my coffee.
For some reason I thought the case you got working was with a 3.18 kernel, but it seems Guodong's mainline rebase tree already is working w/ uboot?
Yes. Guodong's mainline rebase tree can works well.
So is it just 4.1 that is having problems? And if so, how critical is it to have 4.1? I'm currently working to move the hikey AOSP side to 4.4, so I'd like to understand the need better so I can prioritize this issue.
Now 4.1 has problem. There have no any output from uart0/3 after uboot jump to kernel.
Thanks, Leo Yan
