mDOC H3 can function both as a flash disk and as the system boot device.
If mDOC H3 is used both as a flash disk and as the system boot device, it contains the boot
loader, an OS image and a file system. In such a configuration, mDOC H3 can serve as the only
non-volatile device on board.
When using mDOC H3 as the system boot device, the CPU fetches the first instructions from the
mDOC H3 Programmable Boot Block, which contains the IPL. The IPL handles the required
platform initializations, and then loads the required image or OS Boot loader from its dedicated
partition.
SanDisk’s DOC Driver, SDK and utilities enable the construction of a proper mDOC H3 layout
in order to support the boot sequence. For a complete description of these tools, refer to the DOC
Driver 1.0 Block Device (BD) Software Development Kit (SDK) developer guide and the DOC
Driver 1.0 Software Utilities developer guide. These tools enable the following operations:
Figure 10 illustrates an example of a boot sequence.
