The F28P550SJ9 boot ROM contains bootloading software that executes every time the device is powered on or reset. Two pins, GPIO24 and GPIO32, are wired to the boot select switch (S3). By default, both pins are set HIGH (1) so the device boots from Flash. For more information on the F28P55x boot modes, see the TMS320F28P55x Real-Time Microcontrollers data sheet.
Boot Mode | GPIO24 (LEFT) | GPIO32 (RIGHT) |
---|---|---|
Boot from parallel GPIO | 0 | 0 |
Boot from SCI / wait boot | 0 | 1 |
Boot from CAN | 1 | 0 |
Boot from flash (default) | 1 | 1 |
