Hi,
I've had some recent success with my gru-kevin and wanted to update you on this. Long story short, I can boot from SPI flash and have the display, keyboard, eMMC, microSD card, USB disks all work (however with some hacks); but can't boot into Linux. Things seem to hang shortly after "Starting kernel..." but I don't know if something fails in U-Boot or if I get a kernel panic. (I still have no serial console).
There are three relevant branches on my GitHub repo now, please have a look. The first is for what I intend to send upstream soon enough. The other two include hacks and additional patches that build on top of the first, meant to improve things on a per-board basis:
https://github.com/alpernebbi/u-boot/tree/rk3399-gru-chromebooks https://github.com/alpernebbi/u-boot/tree/rk3399-gru-kevin https://github.com/alpernebbi/u-boot/tree/rk3399-gru-bobI have no idea if the gru-bob versions work. I just thought things I did for gru-kevin are applicable to it as well and decided I should include them in case anyone wants to test.
I also want to ask you some things I'm indecisive about, before posting the rk3399-gru-chromebooks branch as patches.
Most of the patches are small config and dts changes that I've grouped by whatever effect they have. Should I squash them into one commit each for config/dts?
Probably best.
Simon, I've edited some of your patches and kept you as author & sign-off. Are you OK with the edited versions, am I doing things right? See:
https://github.com/alpernebbi/u-boot/commit/8c658b7811f4324cd699bd035e802f93...
https://github.com/alpernebbi/u-boot/commit/c2c68f23e10a51b8d34c00764a33fc84...
https://github.com/alpernebbi/u-boot/commit/995454193906e04bfb4e0e38f2bf1a18...
LGTM
Marty, your (second) chromebook_kevin support patch didn't have your sign-off. Is it OK to add it? See:
https://github.com/alpernebbi/u-boot/commit/4cee351e012dc26714640e868069b5cc...
I also think I should squash my gru-kevin changes into that commit, add a commit message about board status, and keep Marty as author & sign-off while adding myself as Co-authored-by & sign-off. Any better ideas on how to structure the patches?
Do both of you want to be in /board/google/gru/MAINTAINERS? I have three of us listed there right now, but no idea if that's fine with you two.
Hope you can spare time on this.
I actually have bob in my lab but I have not tried the Chrome OS boot script on it. I could probably add kevin.
