Pix: i think nobody enabled it yet. but it should be a designware (the register layout matches)
<Pix>
interesting, gonna play with it
<Pix>
i went further with kernel 4.14, it was my gcc version (4.8 was too old) that created non-bootable binaries
<Pix>
afterwards, i had kernel hang on PCIe init, so i need to disable it ( my guess is sapphire without excavator is not an usual setup)
<Pix>
and finally i'm beginning to boot the fedora "standard" aarch64 kernel that embeds the rk drivers & dtb, to have a full distribution working ( i'm figuring out what i need in the initramfs atm)
<Pix>
it's a nice toy :)
<beeble>
excavator doesn't add anything at all to pcie
<beeble>
all the pcie stuff is on sapphire
<Pix>
yeah but not connected to anything
<Pix>
there is nothing between the sapphire large connector and the "final" pcie connector on the excavator ?
<beeble>
there is a pcie connector on the excavator? mine only has one on sapphire
<beeble>
ah
<beeble>
it is on the vmars one
<beeble>
varms
<Pix>
ah yes
<beeble>
but still. there isn't anything essential there. link training should timeout and thats all
<Pix>
hmm ok

Pix: so, you managed to boot your kernel ?
<Pix>
nearly at the end yes
<Pix>
i'm not out of the initramfs yet, but it will come
<Pix>
i load enough modules in it to see the emmc
<Pix>
i just need to boot with the rd console and check what's preventing the initramfs to pivot to the real rootfs
<rtp>
for the external sd card, make sure you have at least rk808 and rk808-regulator
<Pix>
i'm not using it ( yet ), atm only the onboard emmc
<rtp>
oh, ok
<Pix>
i plugged a small 8G card, but i plan to use it as a recovery kernel/miniroot
<Pix>
the board will be in a datacenter, headless
<Pix>
so i need some thinking about how to never have to go there to manually switch on/off :)
<rtp>
not sure the sapphire can power itself back on after power failures :(
* rtp
plans to use its sapphire mostly to compile stuff
<Pix>
yeah it can it's a physical power switch
<Pix>
i'm looking at remote controlled psu or, if i can make it work, the watchdog

yey
<Pix>
booting upstream fedora kernel on a centos 7 :)
<Pix>
(on a rk3399)
<Pix>
had to blacklist phy-rockchip-pcie module
<Pix>
it hangs the sapphire varms board
<rtp>
hm. I guess that pcie stuff should probably move to the excavator dts but I dont remember seeing it hanging on my board.
<Pix>
it's the same dts
<Pix>
well more like there is no dts for the sapphire board alone
<rtp>
making a dts for the standalone board is easy :)
