[TDA4]Quention about IPC_echo_test demo

Linda Xie

HI,experts,

I using SDK_7.03 and want to run ipc_echo_test app. I make all cores image follow the manual, but they don't work properly.

1.In what way do we set one of the cores to Host and the other to Romote?

2.We want to use this test to get the communication time of IPC between cores

3.Can you describe the make command in detail?

Regards,

Xie

Hi,

Did you follow the user guide to build and run the ipc echo test example?

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/07_03_00_07/exports/docs/pdk_jacinto_07_03_00_29/docs/userguide/jacinto/modules/ipc.html#ipc

What error are you seeing? Can you share the log?

Regards,

Stanley

Hi,Stanley

I follow the user guide to build and run the ipc echo test example. then I use ccs to download files to every cores but there are no any log to prinft to UART or ccs console. so what's going on here?

Hi Xie,

If you run ipc echo test example, the trace is in the trace buffer, not output to console. You have to read the trace from buffers directly.

You can run baremetal ipc echo test which should output the trace on console.

If you run Linux on A72, you should see trace from UART console.

Stanley
