CompuLab provide a u-boot that supports dtb, and afaik, it's supported in mainline u-boot as well.

They do? The hardware I have came with a very old u-boot. Got a link to the newer one? -Olof On Thu, Sep 19, 2013 at 5:59 PM, Steev Klimaszewski <steev@pwnieexpress.com> wrote: > CompuLab provide a u-boot that supports dtb, and afaik, it's supported > in mainline u-boot as well. > > On Thu, Sep 19, 2013 at 7:56 PM, Olof Johansson <olof@lixom.net> wrote: >> This is needed on TrimSlice, since the u-boot on that hardware is too old >> to support native device tree booting.

Missing functionality includes PCIe Ethernet and HDMI, but everything else works fine IIRC. You can flash it using: https://github.com/NVIDIA/tegra-uboot-flasher-scripts (read README-developer.txt first, then README-user.txt)

Unfortunately lack of PCI-e makes it hard to network boot (unless I add a redundant usb-ethernet adapter on it). Hmm. -Olof

I always just use USB even on TrimSlice since it's easier to move the USB connector than the network connector when switching machines:-) PCIe works in Linux now though, as of v3.12-rc1.

I have a local branch that makes it work at least on Beaver, but it causes the kernel PCIe to fail for reasons that I haven't tracked down yet. Thierry

This is needed on TrimSlice, since the u-boot on that hardware is too old to support native device tree booting. Same for any device that currently run fastboot, but none of that hardware is supported in mainline today; or at least there are modern u-boot ports for it.
