question about msgq

Error indicates the MessageQ_heapID set in the message is invalid and greater than the maximum number of heaps configured in MessageQ module. When do you get this error ? What change did you make to cause this error ?

hi badri

Because we didn't see following messages in our another version of SW, we didn't patch rdk3.0.1 about ipc-msgq and we use 8ch analog, After testing stability for 3 weeks, we got provided messages as the above.

*** HeapMemMP_free: Free size is overlapping

        Error [0xfffffff9] at Line no: 1458 in file /home/TI-8168/DVRRDK_03.00.00.00/ti_tools/syslink/syslink_2_10_02_17_patched/packages/ti/syslink/utils/hlos/knl/Linux/../../../../../../ti/syslink/ipc/hlos/knl/HeapMemMP.c

Any idea?

I don't understand . Pls mention

Codebase used: RDK 3.0.1 - What issue ? What is the application being tested ? WHen do you get the error ?

Codebase used: RDK 3.0.1 + MSGQ alloc patch - What issue ? What is the application being tested ? WHen do you get the error ?

What are the changes you have done to RDK ? I need detailed info diff of every change done in dvr_rdk under mcfw folder.

Your application already has a memory corruption issue  which causes M3 exception. Have you fixed that ? Memory corruption can result in this issue.

code base is RDK 3.0.0, I'm testing SCD stability for long time with 30fps, and DSP will feedback .. And I didn't patch ipc-msgq from 3.0.1

Your application already has a memory corruption issue  which causes M3 exception. Have you fixed that ? Memory corruption can result in this issue.

-> Mm..I'm trying to reproduce this, and got this result. I'm try to figure out where's it...

As I got the message, I got other message. See attach for your reference1680.logs.txt

by the message below, could I got any further info??
