Agreed! I also prefer a Fedora solution. Especially since we, as a server WG, are considering creating a list of reference boards that we care about in particular. And due to its characteristics, the Rock Pi would be a suitable candidate for such a list.

What I did:

I studied your https://nullr0ute.com/2021/05/fedora-on-the-pinebook-pro/ and noted that Fedora provides 2 variants of itbloader for that board (*.img & *.spi). The same is true for some other Rockchip 3399 boards, but for Radxa Rock pi 4 there is only the one img variant. This left me a bit in doubt whether Fedora currently supports spi on Rock Pi. Before its hardware version 1.4, the Rock Pi did not have SPI soldered on. So there was nothing to test until now. And the described procedure is specific to pine and I couldn't find a way to get this to work on Rock Pi.

Nevertheless, I studied user documentation of Radxa, Rockchip and u-boot and finally tried:

rkdeveloptool db rk3399_loader_spinor_v1.15.114.bin
rkdeveloptool wl 0x40 /usr/share/uboot/rock-pi-4-rk3399/idbloader.img
rkdeveloptool wl 0x4000 /usr/share/uboot/rock-pi-4-rk3399/u-boot.itb
rkdeveloptool rd

and also a newer version rk3399_loader_spinor_v1.20.126.bin

Nothing visible happened after reboot and unfortunately I don't have a serial terminal at hand. I couldn't find any information about the file u-boot-rockchip.bin in Fedora so I didn't try anything with that, and gave up for the time being.


Thanks
Peter
