5.11 Updating U-Boot

Procedure

This procedure describes how you can update U-Boot via the U-Boot command line interface.

It is assumed that the new U-Boot image is placed in the download directory of a TFTP server

which has network access to the ATCA-F120. All shown files names and IP addresses were only

chosen for illustration purposes. The described procedure consists of updating the stand-by

boot flash and then switching the boot flashes, so that after the next reset/boot flash the ATCA-

F120 boots from the new active, previously updated boot flash.

1. Connect to U-boot as described in Accessing U-Boot via the Serial Console on page 87

2. Specify the IP address of the ATCA-F120 itself and of the TFTP server which contains

the U-boot image by entering the following U-Boot commands:

setenv ipaddr <IP address of ATCA-F120>

setenv serverip <IP address of TFTP server>

3. Depending on your network configuration, you may have to specify a gateway IP

address as well as a netmask. To do so, use the following commands:

setenv gatewyip <gateway IP>

setenv netmask <netmask>

4. Load the image to the RAM.

tftpboot $loadaddr <U-boot file name, for example: u-boot-

1.1.6-59.bin>

We recommend to update the U-boot firmware via BBS/Linux or via the shelf manager. Refer

to the respective documentation for further details.

When updating the U-Boot image, the U-Boot boot parameters are not updated. They remain

as they were before the update. The boot parameters are stored separately from the U-Boot

image in a memory area within each boot flash. See also Table "Linux Devices" on page 96.

Each of the two U-Boot firmware images in the two flashes holds a separate set of U-Boot

environmental variables/boot parameters. Therefore, after switching to another boot flash,

you may need to reconfigure the boot parameters/environmental variables of the new U-

Boot image according to your needs.
