Load and start a RedBoot RAM instance

There are a number of choices here. The basic case is where a RAM mode image has been stored in the FIS (flash Image System). To load and execute this image, use the commands:

RedBoot> fis load RedBoot[RAM]
RedBoot> go
If this image is not available, or does not work, then an alternate RAM mode image must be loaded:
RedBoot> load redboot_RAM.img
Entry point: 0x060213c0, address range: 0x06020000-0x060369c8                   
RedBoot> go

Note: This command loads the RedBoot image using the TFTP protocol via a network connection. Other methods of loading are available, refer to the load command for more details.

Note: If you expect to be doing this more than once, it is a good idea to program the RAM mode image into the flash. You do this using the fis create command after having downloaded the RAM mode image, but before you start it.

Some platforms support locking (write protecting) certain regions of the flash, while others do not. If your platform does not support locking, simply ignore the fis unlock and fis lock steps (the commands will not be recognized by RedBoot).
