How to install on Akitio Mycloud mini (oxnas)?

Hi,

I bought a Akitio mycloud mini and tried to install via serial / tftp however I can't get the initramfs-uImage to work. After transferring the file the system starts to boot but hangs when it tries to bring up the network. This happens on both 19.07 and snapshot images.

The 18.06 initramfs-uImage does boot via tftp but the network does not work. So I get a shell on the serial console but can't SCP or download the sysupgrade file to complete the install.

Does anybody have an idea what is going wrong?

I've just tried to tftp boot the pogoplug v3 initramfs-uimage and that works without issues. It boots and has a working network connection. So something seems to be wrong with the Akitio mycloud mini initramfs-uImage file.

This issue is still a problem with the OpenWrt 21.02.0-rc3 images. The akitio_mycloud-initramfs-uImage hangs when booting:

I've left it at this point for ~30 minutes.
Retrying using the Pogoplug Series 3 initramfs image will result in an available console.

Are you sure it isn't done?

Punch enter..

As I said it is hung! Pressing "Enter" does nothing. I'm pretty sure it's an issue with the DTS as I've determined that of all the oxnas images available those that do not enable pcie0 will boot up to a console on this device, but those that enable pcie0 (including the DTS provided for this device) hang! Once I've confirmed my testing I will be submitting a patch.

It appears that this device never actually had stable support. The current trunk image hangs at:

Starting kernel ...

With no other output on console and appear hung even after 15 minutes. Both 22.02.0rc3 and 19.07.7 hang at the same location as the above message indicates. 18.06.9 actually boots! But it has issues:

Note that it is in failsafe mode even though no buttons were activated. Copying the ubifs-sysupgrade.tar file to /tmp and doing a sysupgrade then results in a system that boots with no network access!

I've just tried the 21.02.2 image and the issue is still there. I can load the initramfs uImage via tftp but it hangs during boot.

The nas can boot to a working system by using the mitrastar or pogo3 uImage initramfs files.

When I modify the dts by removing the pcie sections and also adjust some of the nand stuff I can compile an image that boots. However it hangs in failsafe mode since it thinks a button has been pressed.

I've modified the dts file based on the other oxnas devices and with some trial and error. I had to disable all the keys / buttons to avoid the nas going into failsafe on boot. The following dts file generates a working initramfs uImage that can be booted via tftp.
