SK-TDA4VM: IPC Echo test throws error

Deepankar maithani

Part Number: SK-TDA4VM

Following the instructions in the documentation QNX IPC, I built the firmware for the remote cores and added them to the rootfs partition under /lib/firmware. Then i started the test on QNX by running ./ipc_test -s. I am getting the following output

J7EVM@QNX:/ti_fs/tibin# ./ipc_test -s

!!!Exiting the test with failures!!!

It is not clear to me what should i make out of this output. What does returned with code 0 mean. What does Ping- 10, pong - 10 completed mean.

Hello Deepankar,

Are all the remote core firmware images loaded properly? To confirm, can you share the full bootlog include messages from the bootloader?

Thanks.

I see that there are some cores not loaded. I updated the rootfs folder again with new firmware and here is what i get now. It seems to work now.

What does "RPMessage_recv returned with code 0". Where can i read more about the RPmessage API and source code?

Hello Deepankar,

The engineer is out of office until 5/8, please expect a ~1-2 day delay.

The source code for tiipc-mgr and sharedmemallocator modules can be found in the SDK install path.

<PSDK_INSTALL_PATH>/psdkqa/qnx/resmgr/ipc_qnx_rsmgr/resmgr

<PSDK_INSTALL_PATH>/psdkqa/qnx/sharedmemallocator

Thanks.
