i.MX53 SODIMM PC Flashing images

This section describes flashing Barebox, Linux kernel and filesystem images.

If module could not start loading Barebox from its memory, recover bootloader by following these steps first.

Flashing bootloader

Enable serial boot mode by placing a link between pins 1 and 2 of H902 (BOOTMODE) header:

Make sure FTFP server is up and running. Download the latest image and store it into the TFTP directory.

A local network without DHCP control is recommended. Define network parameters for this network first:

eth0.ipaddr=192.168.0.154
eth0.netmask=255.255.255.0
eth0.gateway=192.168.0.1
eth0.serverip=192.168.0.77

Erase NAND Flash memory:

erase /dev/nand0

Download bootloader image from TFTP server:

tftp vmx53/barebox.bin /dev/nand0.barebox.bb

Power off the board and disconnect the JTAG cable as it is not needed anymore. Switch the module to the normal boot mode by changing H902 jumper on the base board (short pins 2 and 3 together):

Power on the board. The module boots from the new Barebox stored in its memory:

Flashing Linux kernel

Download the latest kernel image and store into the TFTP directory.

Before loading the image, set the server address and update the bootloader:

eth0.serverip=192.168.0.77
update barebox tftp vmx53/barebox-2012.09.0-vmx53-vpac2.bin

Restore bootloader environment to the default state and reset the board afterwards:

erase /dev/nand0.bareboxenv

Update Linux image (using the latest official Voipac image is highly recommended):

#update kernel tftp vmx53/zImage-2.6.35.3-vmx53-vpac0.bin
update kernel tftp vmx53/zImage-3.12.13_vmx53_20151129.bin

Flashing filesystem

Download the latest filesystem and store into the TFTP directory.

Update the stored filesystem image:

update rootfs tftp vmx53/rootfs-ubifs-bb-1-18-vmx53-vpac0.bin

Reset the board. The module boots with newly downloaded files. The default vmx53 login is root without set password:
