Hi sir,
I am using TMS320C6748 DSP with External NOR Flash using.
Actually in .cmd file DSPL2RAM i used it is booting from NOR FLASH, when i will change to DDR2 in .cmd it's not booting.
In AIS Gen all settings given properly please could you give me some suggestions.
below i am attaching AIS Gen setting images and (whatever in Debug mode DDR2 worked fine used) OMAPL138_LCDK.gel attaching.
and i am attaching my gel(OMAPL138_LCDK) file also sir,

But through serial port not displaying any thing from DDR2 settings,
from Internal DSPL2RAM it's working fine sir.
Any Specific entry point i want add because its disable i used.
Could you give me some suggestions.
Thanking you,
Regards,
Ramachandra
