Manual installation

U-Boot

Not mainline.

Ethernet (ping, tftp), USB (usb start) and SD (sd rescan) are not working. The only working way to load an external kernel appears to be via serial.

loady $kernel_loadaddr
loady $fdt_loadaddr
loady $rootfs_loadaddr
fdt addr $fdt_loadaddr
fdt resize
env set bootargs "initrd=$rootfs_loadaddr,0x$filesize"
env set bootcmd 'booti $kernel_loadaddr - $fdt_loadaddr'

Kernel

v4.13-rc1 added initial RTD1295 support.

A Lake I .dts does not yet exist.
