Radxa Cubie A7A/A7Z - Allwinner a733

[Nick A]

@Sand_Death I just updated my build with @alexc's BSP changes, which include the latest AIC8800 drivers. I'm building an image right now, so I haven't tested it yet.

I haven't tested Ethernet either. Maybe Alex can help you with that.

My board is A7Z so unfortunately I couldn't fully test the Ethernet drivers.

Hi @qq20739111 / @humanus, any luck with the on board Ethernet?

 

FYI, my new version utilizes mainline MMC drivers as well. And I'm looking into PCIE at the moment.

OK, it looks like the BSP PCIe driver might have some issues related to power management. I’m not entirely sure of the root cause yet, but when I connected an NVMe drive, it got extremely hot and failed to initialize properly.

The NVMe dmesg output suggested adding the following kernel parameters:

nvme_core.default_ps_max_latency_us=0 pcie_aspm=off

 

This resolved the NVMe issues on my side. I’ll try to dig deeper into the root cause, but @humanus please give it a try as well.
