U Boot for WRT Series

The examples, output, etc. in this article are for the WRT32X. The WRT3200ACM and various iterations of the WRT1900AC, WRT1900ACS, etc. are similar.

There are just some quick notes here.

Command: mtdparts (output from WRT32X shown)

active partition: nand0,0 - (uboot) 0x000000200000 @ 0x000000000000

The above seems (not verfied) to be mounted as: ubiblock1_0

To change active partitions: chpart nand0,X (where X is one of the above #s)

Do NOT do this (ONLY AN EXAMPLE, the U-Boot documentation would lead one to believe this "attaches" a partitions, nope, it is equivalent to using the FDISK command in DOS to actually create a partition.): To create (IE overwrite an existing partition) and "attach" (not "mount" apparently) a UBI Parition: ubi part NameOfPartition (like firmware2, IE ubi part firmware2)

For information: ubi info (only works after the above "attach" command is issued)

...and another 2 hours of research after this, and no luck what so ever in figuring out why everyone on the planet says that something like "ubi part firmware2" will attach a UBI volume, when on the WRT32X Marvell version of U-Boot, it executes a complete "FDISK" (guess what the F stands for here), and wipes everything on the existing partition (checked it twice and it DOES hose the partition).

Environment Variables

Note the bootcmd and nandboot variables. Essentially the boot command (setenv bootargs console=ttyS0,115200 root=/dev/mtdblock6;nand read $defaultLoadAddr $priKernAddr $priKernSize; bootz $defaultLoadAddr) breaks down as follows;

• setenv bootargs console=ttyS0,115200 root=/dev/mtdblock6
• nand read 0x2000000 0x0900000 0x0600000 (this equates to the above "firmware1" mtd partition, which is defined by OpenWRT as mtd5 / kernel1 (primary kernel image & mtd6 rootfs1 (ubi))
• bootz 0x2000000
