c6455 dsp doorbell interrupt

vaishnavi gujjula

hi all,

i have a doubt on how srio doorbell interrupt.How to to configure Doorbell Packect?

I am interfacing two 6455 DSPs using srio. One DSP is configured as master and other as slave.

In master i had already set doorbell configuration.But I dont know where to set ICSR,ICCR ,ICRR,ICCR2 and INTDST Registers.Whether I have to set these registers in Master or in Slave?

If i send Doorbell packect from master to slave ,How can I check whether the doorbell packect is reached to slave or what?

Thanks in advance.

Regards,

Vaishnavi.

Vaishnavi,

You may find more things than I did from a search at TI.com of "c6455 workshop" (no quotes), but one of the links was to this forum thread that gives the links for files and materials from a DSK6455 workshop. If memory serves, this workshop included a lab/example for doing SRIO reads/writes between two DSK6455 boards.

You are surely using the CSL for the C6455. Are there not examples there for sending or receiving doorbells?

Regards,
RandyP

Hi Vaishnavi,

For 6488, the SRIo boot example is available which uses the door-bell-interrupt for communicating between two TCI6488 DSPs. You can have a look and consider re-using it for 6455 DSP.

I have attached the package here: - /cfs-file/__key/communityserver-discussions-components-files/791/4263.Boot_5F00_test_5F00_package.zip

Path of the source after unzip the attached one: \"Boot_test_package\boot_test_package\SRIOboot\Boot_From_Another TCI6488"
