01:02 <user21> @CounterPillow how do I build this https://gitlab.collabora.com/hardware-enablement/rockchip-3588/linux without NPU but the right device tree so I can use with debos later

01:02 <user21> and boot it on the rock 5b+

11:13 <antoan> Hi guys. I have a question for Rockchip knowing folks

11:14 <antoan> I'm trying to run stock linux on rk3568 android board, and have some difficulties with it. I'm basing my linux distro on Yocto and meta-rockchip layer using kernel 6.12.

11:17 <antoan> But after u-boot passes control to the kernel, nothing happens. The last message printed to uart is starting kernel

14:18 <user21> depends what boot loaders, device trees, SPI/SPL flashes etc, a lot can go wrong

14:19 <user21> CounterPillow: I'm declaring success. Rock 5b+ with 6.14.5 kernel and NPU is working !

14:19 <CounterPillow> user21: \o/

14:20 <user21> got all the patches and mistakes squared out

15:03 <user21> collected all the patches from here

15:03 <user21> kernel space: https://lore.kernel.org/linux-rockchip/20250225-6-10-rocket-v2-0-d4dbcfafc141@tomeuvizoso.net/

15:03 <user21> device tree: https://gitlab.collabora.com/hardware-enablement/rockchip-3588/linux/-/tree/fratti-tomeu-npu-rk3588?ref_type=heads

15:03 <user21> used armbian build framework with support from this forum, shuffled a few things around and made it work

15:03 <user21> how do I contribute all this into a nice looking package ?

18:57 <user21> company is looking for kernel developers to hire

20:59 <sigmaris> user21: one option is to just wait for the Mesa and kernel changes for the NPU are merged, they'll arrive in nice looking packages in distros eventually :)

21:03 <sigmaris> user21: as far as hiring kernel developers, Tomeu mentioned on https://blog.tomeuvizoso.net/2025/05/rockchip-npu-update-5-progress-on.html that he was wishing to make faster progress on it but had to take some other work to pay bills. If your company values the upstream support, maybe they could sponsor Tomeu's work on the NPU, and that would help it get upstreamed and into distro packages

21:38 <user21> talked this morning with him, but we need more hands in addition to that

21:44 <CounterPillow> user21: https://www.collabora.com/contact-us.html - additionally you can also contact Collabora (who I currently work for), we have a few people working on Rockchip mainline stuff and we do contract work for customers looking to use it
