Manual installation

U-Boot

Not mainline.

Ethernet (ping, tftp) , USB (usb start) and SD (sd rescan) are not working. Serial seems the only way to load an alternative kernel (e.g., via minicom).

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'
b2ndbc

Kernel

v4.13-rc1 had initial RTD1295 support.

An Ava .dts for 4.14 is in the works.
