Hey Alexandre,
Here is a link to a precompiled and signed non verified uboot for the nyan-big chromebook: https://drive.google.com/file/d/0B3uMpbwOyYIadEtPdVpHV1piWEU/view?usp=sharing This is how you would boot a kernel from an sdcard that had uImage and tegra124-nyan-big.dtb in ext2 formatted partition on /dev/mmcblk1p3 mmc dev 1 ; mmc rescan 1 ; ext2load mmc 1:3 0x81000000 uImage ; ext2load mmc 1:3 0x82000000 tegra124-nyan-big.dtb ; bootm 0x81000000 - 0x82000000 Hope that helps On Fri, Jul 21, 2017 at 3:48 AM, Simon Glass <[email protected]> wrote: > Hi Alexandre, > > [...] > > >> Hi , My Name is Alexander and i need some tip information about > U-boot > >> Board Nyan-Big to runinng Linux v4.4.x.x. > > > > Can you please resend this to the U-Boot mailing list and cc me? > > > > Thanks, > > Simon > >> > >> > >> I compiled source 4.4.0.70 Ubuntu distribution in chroot environment in > my > >> chormebook Tegra Tk1. > >> After compilation the generated files were the following: > >> > >> > >> > >> [aperfeito@alarm boot]$ ls -l > >> total 24992 > >> -rw-r--r-- 1 root root 98874 Jul 13 14:54 config-4.4.70-ARCH > >> -rw-r--r-- 1 root root 8277506 Jul 13 14:54 initrd.img-4.4.70-ARCH > >> -rw-r--r-- 1 root root 2033244 Jul 13 14:54 System.map-4.4.70-ARCH > >> -rw-r--r-- 1 root root 15175680 Jul 13 14:54 vmlinuz-4.4.70-ARCH > >> > >> I also compiled the u-boot-tegra in the same environment in chroot > Ubuntu > >> Xenial distribution these were compiled according to the email of Tom > Warren > >> send before > >> > >> Make 'nyan-big_defconfig' and everything ok as you see below the > >> generated files: > >> > >> > >> [aperfeito@alarm u-boot-tegra]$ ls *.bin > >> u-boot.bin u-boot-dtb-tegra.bin u-boot-nodtb-tegra.bin > >> u-boot-dtb.bin u-boot-nodtb.bin u-boot-tegra.bin > >> > >> Now is the tip I'm asking you: > >> I have two suggestions on how to put this in the KERNEL partition of my > >> USB. > >> My USB has two partitions > >> To 1st.
