8.2 Bootloader Image
<Bootloader image> is also known as the second bootloader and is the first thing loaded into
memory for a factory-created DUT (for example with an empty flash).
Know that this image has SFDP information, which is important sflash type information, so always
load this image before loading the other images.
If you get a new SDK, then you always load the <Bootloader image> first.
1. Power on the DA16600 board.
2. At the [/DA16600] prompt, type reset to go to the Mask ROM prompt [MROM]. See Figure 14.
