CCS/DRA75: Integrating an IPC example with uart example

Padmesh K Gopi

Part Number: DRA75

Tool/software: Code Composer Studio

Hi,

I wanted to know how to integrate the ipc "ex01_hello" with the csl uart_test example. I'm trying to create a communication between two cores a15 and M4. I have made a15 the sender and M4 as the receiver. I wanted to display the message received at M4 to be displayed through UART

What modifications should I need to do in the code ?

Regards,

Padmesh

Hi Padmesh,

What is your objective?
The functionality you have described is part of CSL mailbox example as well as IPC example (PROCESSOR_SDK_VISION_03_05_00_00\ti_components\drivers\pdk_01_10_01_06\packages\ti\drv\ipc_lite\examples\ipc_mbx\).
Where is the "ex01_hello" example you are referring to?

Rishabh

Hi Rishabh,

ex01_hello is located at ipc_3_47_01_00/examples/DRA7XX_bios_elf. This program facilitates the communication between 2 cores. Following this example as explained above, the output received at the READER core is to be displayed in the UART window. I was thinking of integrating this example with csl uart test example. Is it possible to integrate them ? How do i do it ?

Hi Padmesh,

One is IPC library example and another is PDK CSL example. It is not trivial to integrate them and I would suggest you not to do the same.
It is not very clear to me what exactly you are trying. Can you state your objective to help you better.

Hi Rishabh,

I'm actually trying to send some data through a15 core to M4 core. Will I be able to see the transferred data through uart ?

To observe the output in the normal IPC example is to go to the ROV in CCS. Instead I'm trying to modify it so that i'll be able to see the output through uart terminal.

Hi Padmesh,

This particular IPC example is not integrated with CSL or PDK. It is a standalone example in IPC package.
In case you want to use UART to see transferred data you should use IPC lite (PROCESSOR_SDK_VISION_03_05_00_00\ti_components\drivers\pdk_01_10_01_06\packages\ti\drv\ipc_lite\examples).

Hi Rishabh,

I'm not able to find that example in my version of processor sdk.

Hi Padmesh,

I work on Processor SDK Vision.
I have asked an RTOS automotive expert to help you on this.
Please expect a delay of few days as expert is on vacation.

Hi Padmesh,

I would suggest checking with Ganesh from your company. He has gone through similar exercise with IPC and some information is tracked in these threads:
e2e.ti.com/.../737419
e2e.ti.com/.../746486
e2e.ti.com/.../749110

Please try these and contact Ganesh to perhaps share his setup which enables this configuration for you.

Thanks,
Stephen

Hi,

I haven't heard back from you, I'm assuming you were able to resolve your issue.
If not, just post a reply below (or create a new thread if the thread has locked due to time-out).
