Flow Chart of Booting From Suspend Mode
Bootloader
The bootloader is the first program when booting that controls what the
CK1 does at cold boot. It reads from the outgoing serial port and sees if
there is a character sent to the CK1. To send commands to the CK1 from
a PC, connect the serial dock to the PC and place the CK1 in the dock.
For help, see the CK1 Serial Dock Quick Start Guide (P/N 073772).

When cold boot is started, the bootloader enters Menu mode if it receives
an ESCAPE key from PC. You can download an application to SDRAM
and run it at SDRAM, run the diagnostic program, enter BIOS and boot
the device, and run the Flash writer program. The downloaded program to
run should contain no relocation table that is placed in the 0x0C200000
as the start of the text section.
