I was close to get this working with u-boot 2016.05. I had to stop when being too busy with works.

Sure! this is the new driver:

Thanks I want to test my 88e6161. Btw my original uboot has the ability to read register by a command is it useful to determine register address?

I'm back! I thought I'd dust off the router and try and get DSA working again, but to no avail. Even with the latest kernel and the DSA .dtb, it fails with

mv643xx_eth_port mv643xx_eth_port.0 eth0: [0]: could not detect attached switch
mv643xx_eth_port mv643xx_eth_port.0 eth0: [0]: couldn't create dsa switch instance (error -22)

Full boot log is here: https://paste.ubuntu.com/p/6fPYB7z2rV/

I'm running 4.18.4-kirkwood-tld-1

Any thoughts? I'd love to get this working. Also, through DSA, do we have the ability to change the link status of individual ports?

Interestingly, the dtb from your previous post (https://forum.doozan.com/read.php?2,26854,36051#msg-36051) works.
Not sure of the difference between that one and the one in the latest kernel, but I have all 5 interfaces and can do fancy thinks like

ip link set ethernet1 down

Good to hear there is a work around!

There might have been a change in mainline DTS that were brought in without us knowing about (through include statements). If previous DTS version works with the new kernel, then I think that's probably the reason. I'll boot up my EA4500 to see if I can repeat your problem.

That's the beauty of the DSA switch! And the DSA design is really cool how it works internally.

megal0maniac,

I've just booted up the EA4500. I have no problem with the switch at all.
