interrupt based read write to/from MCBSP on c64+ core of dm6446 without using DSP/BIOS

Hi Akash,

Thanks for your post.

I think, you can start with an app. report using c6000 McBSP for McBSP register configuration as well, you will find sample codes for McBSP in both master and slave mode in App. A and App. B from the app. report below:

To program the c6000 McBSP using CSL, there is a c6000 integration workshop for McBSP below in which there are paper exercise to write a sample code, kindly check the link below:

Hi Sivaraj K,
thanks for your prompt reply.The spra455 is the method to use dma for reading and writing to the MCBSP . However i wanted to use the interrupt (XINT and RINT ) that are invoked in the cpu when data is received at the MCBSP (by setting the RINTM AND XINTM bits in the SPCR register of MCBSP).Inspite of doing all the configurations i am unable to get the interrupt to CPU.It would be helpful if you can please show some example code for interrupt configuration (i.e setting up IER,ISR,ISTP etc for the c64+ core) a simple timer interrupt based LED blink example will also be helpful to me.
i am asking because i think that the MCBSP config is correct at my side as I amable to read/write (loopback the data ) on MCBSP in polling mode but i am unable to do it in the interrupt based mode.So once i get to know the correct method for the interrupt processing(along with the vector table and ISTP onfig on c64+) then i will b able to do it correction.

thanks
