Hello

I've built U-Boot 2020.01-rc4 and found that the PCI bus isn't recognised on my Trimslice Pro. This is using the 'trimslice' default U-Boot configuration file ('make trimslice_config')

I tried 2019.04 and a couple of other older versions, just in case - but nothing recent works.

Is there anything I can do to debug this? The configuration file looks okay, in that the Tegra PCI support is selected.

Thanks s.
