Looking for some help with porting

[Johan Yavari]

Hi,

I'm trying to port ONL to a Delta Networks Kuga7048N switch.

I've made some progress (I think) with the files in $ONL/packages/platforms/delta/powerpc/kuga7048/

I copied the file/folder structure from accton as5610-52x and modified from there.

Gdrive link to my current src and reference docs: 

https://drive.google.com/drive/folders/1RWWWxPg2mGuFzXHdEpZcpeEncH2wzoai?usp=sharing

I'm sure there's plenty of errors in the code, but when I run the build commands, it doesn't do anything with my code folder...

#> docker/tools/onlbuilder

#> source setup.env
#> apt-cacher-ng
#> make powerpc

Any pointers?

Ok so I got it to compile and install but the system does nothing after loading the kernel/fit. Here's the output:

I don't know much about that machine, it's power so we would need to look at the missing items you see in the error. I have a p2020 rdb in storage so I can attempt to boot your kernel there in a day or two.

I feel like maybe the device tree is the issue? where are the first places I should look in the ONL source?

[Johan Yavari]

it was the device tree. factory dtb had cpu compatible as "p2020ds" 

I changed it to p2020rdb. as well as a few other little bits of the dts based on the similar accton 5610

still have plenty of code kinks to work out, but it boots now.
