Streaming is not working on DM8127 IPNC RDK, "low power TRISTREAM usecase"

krinali shah

Hi All,

I am using IPNC_RDK_3.8 with DM8127 based custom board. Currently, I am running "low power TRI_STREAM usecase". With this usecase, I am able to get encoded frames.

But my streaming is not working. When wis-streamer starts, it gives following error,

Error: Memory return Invalid, from function share_memory_init in file ./network/live/appro/wis-streamer.cpp.

Due to this error, wis-streamer is not starting.

I have not changed any default initialization. Still I am getting invalid memory pointer.

I am using following Boot arguments.

console=ttyO0,115200n8 rootdelay=2 mem=80M vram=4M root=/dev/nfs notifyk.vpssm3_sva=0xBFD00000 nfsroot=10.103.0.117:/home/krinali/Gen3Zooter/Source_Package/Current/Source/ipnc_rdk/target/filesys,nolock rw ip=dhcp cmemk.phys_start=0x85000000 cmemk.phys_end=0x89000000 cmemk.allowOverlap=1 earlyprintk

please suggest some solution to resolve this issue.

Thanks,

Hi,

Pl. check the return values of the following function calls in the ..\ipnc_rdk\ipnc_mcfw\demos\mcfw_api_demos\stream\stream.c file:

GetMemMngPhyBaseAddr() and GetMemMngTotalMemSize().

Anand

Hi Anand,

I am getting Physical Base address value garbage (negative).
msgbuf.mem_info.addr = - 2063597568
msgbuf.mem_info.size = 0

I have not changed any memory map or boot arguments. I am using defaults as IPNC RDK 512 MB memory map.

Hi,

Can you send me the complete console log?

Hi Anand,

teraterm6.log

In RDK, default application flow, wis-streamer starts from sys_server before our "ipnc_rdk_mcfw.out" starts.

So, I put 5 seconds sleep, before starting wis-streamer. Now, it is getting proper memory buffer address and streaming starts.

But after running for few minutes, application hangs. ( means some module stops working, may be camera module or encoder module).

No error message comes on console. But all the debug prints from "camera_Link driver" and "encode statistics prints" stop coming and hence streaming also stops.

Please note that I run the application with (CAPTURE_MODE = DDR). so, resizer is running in oneshot mode from ISP link. And I am using full feature usecase, with TRISTREAM streamType.

I have also attached console log file for your reference.

What could be the reason for hang?. Please provide some inputs.

Thanks,

Krinali Shah

Hi,

Can you connect to CCS and check the status of M3 cores?

Also you can put some periodic prints in the Issdrv_IspIsifVdInt() fn in ..\ti_tools\iss_03_80_00_00\packages\ti\psp\iss\drivers\capture\src\issdrv_captureApi.c file as shown below to check is sensor is streaming:

if((gIss_captCommonObj.intCounter[ISS_CAPT_INT_VD_INT0] % 100) == 0)
Vps_rprintf("#### VD int\n");

regards,

Anand
