Installing a NetBSD kernel on DNS 323

2008-08-03T15:54:00.000-07:00

THIS WILL ERASE YOUR LINUX FIRMWARE AND BRICK YOUR DNS 323.

To install a NetBSD kernel permanently in flash, I create a Linux ramdisk with a load address and entry point identical to that of the linux kernel. Instead of a linux filesystem, this image contains a NetBSD kernel. Here is the mkimage command that I used on my box:

mkimage -A arm -O linux -T ramdisk -C none -a 0x00008000 -e 0x00008000 -n "NetBSD kernel" -d /usr/src/sys/arch/evbarm/compile/obj/DNS323/netbsd.bin dns323.img

The following u-boot command will replace the ramdisk with dns323.img permanently. If you brick your device it is your fault 100% of the time. THIS WILL ERASE YOUR LINUX FIRMWARE AND BRICK YOUR DNS 323.

Marvell>>
Marvell>>
Marvell>> loadb r

You will have to use kermit to upload the dns323.img at this point.

At boot time u-boot loads the linux kernel and then overwrites it with the NetBSD kernel. When u-boot jumps into the entry point, NetBSD is started. I have captured the boot process below.
