A64 Mainline - Trouble booting Debian arm64 kernel version 4.13.13

[erikly01]

Hi guys, I've tried my best to get a working Debian image with the mainline kernel, but I don't know how to proceed.

PROBLEM
Uboot won't go beyond the message "Starting kernel ..."

STEPS TAKEN SO FAR
1. Built the Debian kernel and rootfs following the instructions in links below
[a.] https://wiki.debian.org/Arm64Port
[b.] https://debian-handbook.info/browse/stable/sect.kernel-compilation.html
     Compiled with make -j6 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-

2. Built u-boot & installed using instructions below
[a.] https://linux-sunxi.org/Olimex_A64-OLinuXino
       Used files a64-olinuxino_defconfig, sun50i-a64-olinuxino.dtb

POSSIBLE NEXT STEPS
1. I plan to try the vanilla kernel and or linux-sunxi kernel next

Can anyone point me in the right direction to get this working?

[JohnS]

You look to be relying on Debian source(s) and/or linux-sunxi source(s) so did you try asking each of them?

(Probably Olimex supply working uboot+linux and quite possibly those are all they support.)

I expect others will - over time - be interested in this so good luck and please post how you get on.

At a guess (!) maybe your uboot is incompatible with the kernel or the other way around.

I was able to get it to boot Debian successfully, however I get the following kernel errors. 

Does anyone have any clues as to how to resolve these problems?

I hope you've taken my previous post to heart.

Good luck and season's greetings,

Sure, I'll post step by step instructions once I get it figured it out.
