Which exactly version of U-Boot you started?
There was 'a moment' in code when RockPro64 used wrong SPI bus by default.
Possible too that you kept SPI ping too long.

Thank for your response and your blog on installing Fedora on a Rockpro64.
Your blog has been very helpful.
I am using the latest uboot that packaged with uboot-images-arm8, 2020.10.
Are there issues with this versions? Which version should I use? Are there
problems with this version of uboot? Do all the message display through HDMI?
I have a serial console on order.
I think at this point I need to do some more research while I wait for the the
serial console to arrive.
Thank you
Aaron
