You can change this using the ramdisk_size boot parameter. You will definitely need to change this default on the target. On the host, another way to create a ramdisk image is to use the loopback filesystem. This will allow you to avoid having to change the Ramdisk-size of your development host. Take a look at the Loopback-Root-FS How-To. -Jim Mike Flynn wrote: > I need to flash an image larger than 4 megs to an Embedded Planet RPX CLLF > (860T) board with 8 MB of flash.
