IPC client and server program is not working between A15 core0 and A15 core1

Hi,

Assigning this to our IPC experts.
Please note that due to regional holiday in India, half of out team is on vacation. Please expect a delay of 2~3 days in response.

Apologies for delay and thank you for your patience.

Hi Jouse,

           I have working IPC code between host,DSP and M4 which I have attached above, I have modified the above code using ex_ping makefile based project which is generated in IPC_examples in IPC installed directory where the globally declared multiproc list only has host as option but  I also want add  host0 and host1 so that I can implement IPC messagequeue activity between A15 core0 and core1.

I'm not where is that globally declared multiproc list file is located to make the above mentioned changes.

Thanks

Phaneesh a

Phaneesh,

If I understand you correctly, you want to have two hosts, one per core of the A15 processor? Is my understanding correct?

       Yes I need need two cores A15 core0 should be used as server and A15 core1 should be used as client for IPC. I've working code for host and IPU1 but with the existing Makefile based IPC example ping project I have renamed host directory as host0 and copied the message queue server code and similarly created host1 directory and copied client code and in toplevel makefile I have added host0 and host1 for PROC_LIST variable .

In shared region also I have added host0 and host1 memory region in config.bld inside shared directory, when I tried to build the project I've got the errro as follows.

Hi Josue,

             Even in RTOS also it's not supported ??, But in our project we are going to use both A15 core0 and A15 core1 to run a certain task on each cores and we need these cores to communicated with each other so we are trying IPC message queue. If this config is not possible is there any way for IPC between A15_0 and A15_1.

Thanks

Hello Phaneesh,

I believe that might be the case here. I am not saying that it is not possible but it might not be tested nor validated, therefore TI does not support it. I will reach out to the development team to ask and get back to you, hopefully by the end of the week depending on the response time.

Regards,

Josue

Hi Josue,

                Please provide solution for this as soon as possible , this is critical for us.

Phaneesh,

I understand that this is urgent for you. I have contacted the developers and I will reply as soon as they respond. Unfortunately one of the subject experts is OoO indefinitely so please expect extended delays.

Hi Josue,

                Any update on this issue.

Phaneesh

No Phaneesh,

Not yet. Half our team is out for this week due to regional holidays.
