Generic AArch64 on Odroid C2

[Tshaw91]

Hello everybody,

There are some keys steps that I do not understand in order to have the generic AArch64 installation running on Odroid C2. These are instructions given by the website : https://archlinuxarm.org/platforms/armv8/generic

I do not understand this sentence line 2 :

"This is intended to be used by developers who are familiar with their system, and can set up the necessary boot functionality on their own."

What does it means? I understand two things :

- Generic and odroid c2 tarballs are different
- Generic does not boot as-is on every armv8 platform

I am not able to have Arch running on my C2 anymore so I am interested in understanding of how ArchARM has been ported on this device from generic. Is porting an hardware engineering expertise or a software engineering expertise?

Thank you

I just followed the instructions here:

https://archlinuxarm.org/platforms/armv8/amlogic/odroid-c2

Only gotcha was the eMMC needed to be down clocked, but this should now be the default - it was applied to the mainline kernel device tree over a year ago.

@summers,

I did like you, was not sure about the u-boot part and run sd_fusing.sh from the odroid-c2 image.


My odroid is stuck with red and blue lights on and no blinking. Any idea?

Odd, I didn't have that much difficulty, I first installed to an sD card, and booted of that. Then I from there installed on the eMMC, and made that my boot set up.

For you to find more of what is failing to work, you probably need to connect a serial interface to the main uart on the board. That would usually get the low level output during boot, and you can find out where it is failing ...

@lowry

so you have the same problem that I have with arch booting. It is doing the same thing on my C1+ I have red and blue and they are staying passive. No HDMI signal on monitor at all.

I don't know why this is happening but when I made my SD cards with ArchARM or Fedora_x86 back in 2017-2018 it worked well. When I use Armbian or Ubuntu Mate to do it in 2019 it does not work.

When I am looking a little in boot.ini I see an option that is about UHS-1 SD and try to enable/disable it but I have the same result.
