upgrade boot logo, you can key in the path of the bitmap file in the edit box or click

Figure 1.3 Upgrade utility for burn image to flash ROM

Note: The difference between NK.NB0 (Compressed) and NK.NB0 (Normal, XIP) :

The option “NK.NB0 (Normal, XIP)” means that the nk.nb0 will be upgraded directly

to the flash ROM, and “NK.NB0 (Compressed)” means that we compress nk.nb0 first,

and then write the compressed data to the flash ROM. As a result of the different

upgrade type, there are two differences when we use SOM-A :

(1) Bootup time : compressed image take more time in system bootup.

(2) DiskOnChip size : compressed OS image would result in larger DiskOnChip size.

Step4. Press ‘Apply’ button on the dialog. Then the items you select will be upgraded

to the flash ROM. See Figure 1-4.
