Niagara 510: Initial bootup

Booting BusyBox environment from network

Setup networking in uBoot environment

The network interface(s) will need to be configured and operational before you can pull down the necessary files using TFTP.
Follow instructions at: Niagara 510 - Assigning a MAC address in u-boot

Load the necessary files into memory

tftpboot 0xa800000006000000 172.28.0.2:vmlinux_N511_23.xlp
tftpboot 0xFFFFFFFF80100000 172.28.0.2:linux-nae.dtb

N.B. - Replace 172.28.0.2 with the appropriate TFTP server.

Boot the image

bootelf 0xa800000006000000 - 0xFFFFFFFF80100000

Booting BusyBox environment from MMC (SD card)

Place the necessary files on the MMC

Copy the vmlinux_<version>.xlp and linux-nae.dtb files from the Interface Masters SDK onto the second partition of the MMC (SD card).

Ensure the MMC device is initialised in uBoot

mmc init

Load the necessary files into memory

fatload mmc 0:2 0xFFFFFFFF80100000 linux-nae.dtb
fatload mmc 0:2 0xa800000006000000 vmlinux_N511_23.xlp

Boot the image

bootelf 0xa800000006000000 - 0xFFFFFFFF80100000

Getting network interfaces online

In theory, the networking should automatically initialise but I never found this to be the case!
modprobe nae to start the networking:

XLP-Linux login: root
login[1054]: root login on 'ttyS0'
