mpmcl trace not working

Hi,

Have you added the required config options in *.cfg file of hyperlink DSP example code which you running on ARM via mpmcl ?

Please refer to the following TI wiki page, chapter.

processors.wiki.ti.com/.../MCSDK_UG_Chapter_Developing_System_Mgmt

Hi
I added .cfg file . example code. I try to another exmaple project. trace works fine. but hyplnk_K2HC66BiosExample don't work.

Thanks

Hi, Please share the updated .cfg file of hyplnk_K2HC66BiosExample project and also try increasing the buffer size,

Program.global.sysMinBufSize = 0x8000;

var System = xdc.useModule('xdc.runtime.System');

var SysMin = xdc.useModule('xdc.runtime.SysMin');

System.SupportProxy = SysMin;

SysMin.bufSize = Program.global.sysMinBufSize;

/* Configure resource table for trace only.

  Note that, it traceOnly parameter should not

  be set if application is using MessageQ based IPC

  to communicate between cores.

*/

var Resource = xdc.useModule('ti.ipc.remoteproc.Resource');

Resource.loadSegment = Program.platform.dataMemory;

Resource.traceOnly = true;

From FAQ:(Please ignore if you have checked this)

Q: I don't see DSP prints from debugfs

A: Make sure you followed the procedure described above to include the resource table in the image. Care should be taken for the resource table not being compiled out by linker. To check if the resource table present in the image using command readelf --hex-dump=.resource_table . It should have some non-zero data. Another point is, if you are loading same image in multiple cores and if the resource table and trace buffer segments overlap with each other in memory, then there can be undesirable effect. Thank you.

Hi.

This is my cfg file.

I think I added required config.

Thanks.

memoryMappedExample.cfg

Hello?
Nobody here??

Yes. Apologize for the delay.

I have gone through your .cfg file, could not find any issue. I have few more suggestion to check at your end.

1. Please check the MCSDK MPM example is working on your setup . Please find the path below,

PATH: :\ti\mcsdk_bios_3_01_03_06\examples\mpm\mpmsrv_keystone2_example

2. Try Increasing the buffer size in the BIOS configuration file,

Program.global.sysMinBufSize = 0x8000

Please confirm the MCSDK verison used for the testing.

Thank you.

 

Hi Raja

1. I ran another example project(SRIO project), the project works fine, and project I made works fine.

2. I try to increase Program.global.sysMinBufSize, I set 0x800000, the project is not working. I can't find suitable memory size. and My MCSDK version is 3.01.03.06.

and "2 Resource entries at 0x800000", what is means??

Regards.
Shin.

Hi Shin,
Sounds good.
Thanks for your update.

Hi Shin,Great. Thank you.
