Mailboxes vs. MessageQs

Hi Steve,

Basically, Mailboxes allow for communication between tasks while MessageQs allow for communication between processors. You can read more about IPC here: http://processors.wiki.ti.com/index.php/IPC_3.x

You would need to use IPC. You can download the latest version of IPC found here:

You would most likely be using MessageQ and Notify API's.

You would most likely be using MessageQ and Notify API's.

When editing my app.cfg, MessageQ is not an option - just Mailboxes... Suggestion on how to proceed?

Have you installed IPC? Have you tried to run any of the examples? There should be a MessageQ example you can look that has a cfg file setup. The MessageQ module can be defined as var MessageQ = xdc.useModule('ti.sdo.ipc.MessageQ'); but you might need to setup more than that to get it working.

Just made another forum post... when I include IPC, I get build errors like this:

Any ideas?

Thanks.

IPC is consider to be deprecated and is pointing to paths that no longer exist in newer versions of SYSBIOS. You would need to use an older version of SYSBIOS such as 5_42_01_09.

I can try to help you to the best of my abilities, but for future questions on IPC, it may be better to ask on the OMAP-L13x device forum as they would be more knowledgeable on the matter:
e2e.ti.com/.../42

Taking a very close look:

rs\workspace_v6_1\ffff/src/u

What's up with the reversal of the slash directionis?  \  to /. Could that be the root cause?

What's the replacement for IPC that will allow me to be up-to-date with SYSBIOS???

Thanks.

Steve

I think the issue is more "failed: xdc.services.global.XDCException: xdc.PACKAGE_NOT_FOUND: can't locate the package 'ti.bios'".
If you look at the directory structure of the current version of SYSBIOS, you will not find a directory called bios since it changed to sysbios. SYSBIOS v5 does have the expected directory structure. Though, I do agree that the slash reversal is unusual.

That's good to know. Does this mean you managed to get MessagesQ's added to your config?

yes - dropped back to an earlier version of IPC (3.10.2.13), then I could add MessageQ to my app.cfg...
