TDA2EVM5777: IPU2 Inter processor communication between C0 and C1 using mail box mechanism

Harshalkumar Shinde

Part Number: TDA2EVM5777

Hi,

I am working on TDA2EX board and i have to use it for multicore purpose.

I want to know that is their any possibility to communicate between IPU2 processor cores C0 and C1 using Mailbox mechanism.

Thanks

Harshalkumar Shinde ,

The System mailbox is particularly designed for communication between the IPU cores. See "Chapter 19 Mailbox" in the device TRM.

Thanks
Alex

Hi Alex,

Thanks for the reply.
I go through TRM doc they mention word 'subsystem' for IPU cores,
if you have sample code for IPU2 inter core communication using mailbox can you share it to me, so its getting easy for me to mapping.

Hi
we do not have exact sample code for IPC between IPU2 processor cores C0 and C1 using Mailbox mechanism.
But we do have something similar in vision SDK, use PDK from VSDK 3.0,
IPC example can be found under
\ti_components\drivers\pdk_01_07_00_11\packages\ti\drv\ipc_lite\examples\ipc_mbx
