    157 Depending on the size of the SPI FLASH you will likely <strong>need to prune features from your kernel/filesystem</strong>. A good starting point may be the Laguna <a class="ext-link" href="http://svn.gateworks.com/openwrt/trunk/config/cns3xxx/.config_test"><span class="icon">​</span>test_config</a> file which uses a ramdisk and a minimal set of utilities used by Gateworks to test boards. As this <a class="wiki" href="/wiki/OpenWrt">OpenWrt</a> config file specifies an INTRAMFS ramdisk, you only need to flash the kernel which includes the root filesystem.

    159159<ol><li>Use the instructions above to boot from the <strong>Alternate Boot Device</strong> (SPI FLASH) and break out into the bootloader. You can determine that you are booted to the <strong>Alternate Boot Device</strong> by seeing a smaller FLASH size in the boot header or by looking at the output of 'printenv bootcmd' and seeing that it boots a kernel from 0x60080000 (SPI FLASH) instead of 0x10080000 (NOR FLASH)
