Emulation Boot Mode using Code Composer Studio GEL
The CCS GEL file can be used to setup the boot mode for the device during debug. The
“OnReset()” GEL function is called each time the device is reset. This function can be modified
to include a call to set the device to “Boot to SARAM” emulation mode automatically, if desired.
OnReset(int nErrorCode)
{
C28x_Mode();
Unlock_CSM();
Device_Cal();
CLA_Clock_Enable(); /* Enable CLA clock */
// EMU_BOOT_SARAM(); /* Set EMU Boot Variables - Boot to SARAM */
// EMU_BOOT_FLASH(); /* Set EMU Boot Variables - Boot to flash */
}
The GEL file also provides a function to set the device to “Boot to Flash”:
/********************************************************************/
/* EMU Boot Mode - Set Boot Mode During Debug */
/********************************************************************/
menuitem "EMU Boot Mode Select"
hotmenu EMU_BOOT_SARAM()
{
*0xD00 = 0x55AA; /* EMU_KEY = 0x 55AA */
*0xD01 = 0x000A; /* Boot to SARAM */
}
hotmenu EMU_BOOT_FLASH()
{
*0xD00 = 0x55AA; /* EMU_KEY = 0x 55AA */
*0xD01 = 0x000B; /* Boot to FLASH */
}
To access the GEL file use: Tools  Debugger Options  Generic Debugger Options
