test IPC.MessageQ using image_processing demo

Hi,

I have assigned this thread to IPC experts to look into. If you are in the beginning of your development, then we would recommend you to start development with latest Processor SDK released for K2H. Please find the download and migration guide link below my signature.

Thank you.

Hi Shankari G,

I tried to run the pre-built image processing demo from TI rootfs. but it doesn't work normally.

note: I didn't run the matrix browser because I think it is a little complex for a newcomer and we won't use it in my actual project.

The following is what I did on my EVM:

1. Load and start dsp slaves as followings, it seems work fine.

2. Run arm master, it doesn't give any other output after printing out serveral lines of html scripts as followings. 

root@keystone-evm:/usr/share/matrix-gui-2.0/apps/demo_imageproc# ./cgi-bin/image__processing_evmtci6638k2k_master.out

</style>

</head>

3. I added two printf()s respectively right before and right after the function call ipc_start() in master code, compiled and run it and it only printed out the first one. So it turns out that it stops or waits something to happen in the ipc_start(). 

Could you tell me whether that is a normal case or not? If it is, what happens in it? If not, how to deal with it?

Hi Xin,

Please follow this thread to make the image processing demo work normally.

Hi Shankari G,

Thanks for your quick reply.

Now the image processing demo works fine when both master.out and slave.out are loaded and run from linux rootfs.

What I want to achieve is:

(1) Online-debug slave.out via emulator, i.e., I can edit, compile, load and run slave codes, and view run-time status through CCS.

(2) Run master.out from linux rootfs

But after doing the both above, master.out prints out an error ***IPC_start() failed*** as following, or blocks in the function IPC_start().

Could you tell me how to achieve the online debug, or how to let IPC_start() work correctly?

Hi Shankari G, 

Are you still there?
