ipcInM3Link error

Ariel T.

Hi,

Some errors occur in ipcInM3Link like this:

[m3video] 256230: Assertion @ Line: 101 in links_common/ipcInM3/ipcInM3Link_tsk.c: pObj->prd.clkHandle != NULL : failed !!!

What causes it?

Clock create can fail either due to memory allocation failure or due to wrong clock configuration. Have you made any changes to /ipcInM3Link_tsk.c ? If not pls share the full log and usecase file for analysis.

The issue is because the ipcInM3 link is not created but you are starting the link. The file you shared is not a usecase file. I don't see Vsys_create being done . Pls check you usecase file and ensure links that you don't use have linkID set to INVALID ID.

Thanks, Badri. The ipcInM3 link issue has been settled, but another problem arised. I found it does not signal the gVcapVenc_ctrl.wrSem semophore, so it stop here:

status = OSA_semWait(&gVcapVenc_ctrl.wrSem, OSA_TIMEOUT_FOREVER);

And this issue due to no newDataAvailable for encode:

callback.newDataAvailableCb = VcapVenc_bitsWriteCbFxn;

Why the encoder fail to get new data?

Pls check your usecase file where the link connections are setup to ensure you are connecting them correctly and you are starting all links.Also check the logs of Vsys_printBufferStatistics to see in which links buffers are getting locked.

Hi, Badri. The usecase can work normally now. I've changed ipcOutVpssPrm.notifyNextLink from TRUE to FALSE and ipcOutVpssPrm.noNotifyMode from FALSE to TRUE. And it seems no need to start ipcM3In Link.

ipcOutVpssPrm.notifyNextLink            = FALSE;//TRUE;//FALSE;
ipcOutVpssPrm.notifyPrevLink            = TRUE;
ipcOutVpssPrm.noNotifyMode              = TRUE;//FALSE;
