2.1.6 Boot Modes

The F280049C boot ROM contains bootloading software that executes every time the devices is powered on or reset. Two pins, GPIO24 and GPIO32, are wired to the Boot Select switch (S2). Note that S2 is placed upside down, so the OFF (open) position corresponds to a logic 1 and the ON (closed) position corresponds to 0. By default, both pins are set to the OFF position so the device will boot from Flash. For more information on the F28004x boot modes, see the TMS320F28004x Piccolo microcontrollers data sheet.

Boot from Parallel GPIO ON (0) ON (0)
Boot from SCI / Wait boot OFF (1) ON (0)
Boot from CAN ON (0) OFF (1)
Boot from Flash (default) OFF (1) OFF (1)
