Kernel is crashing while inserting vpss.ko

Muhammad Salih

Hi,

I am using AM389x_TI8168 processor. I am trying to insert vpss.ko. Initially I inserted syslink.ko. After I loaded the slaveloader I tried to insert vpss.ko. While inserting I am gettin the below message.

root@dm816x-evm:~/pat_sys# insmod ../vpss.ko

Hi,

This you are seeing on which release of PSP/EZSDK. Have you defined notifyk.vpssm3_sva=0xA0000000

Hi Hardishah,

I set the boot arguments like this.

setenv bootargs 'console=ttyO2,115200n8 rootwait root=/dev/mmcblk16p2 rw mem=256M earlyprink vram=50M ti816xfb.vram=0:16M,1:16M,2:6M ip=off noinitrd notifyk.vpssm3_sva=0xA0000000'

I am using PSP 04.00.02.14 and I downloaded syslink version 2.00.00.78. Please suggest any solutions.

Thanks in advance

Salih

Hi,

Can you please try with syslink.ko and slaveloader binaries provided with PSP14 release. This is because we have tested PSP14 for VPSS.ko and all V4L2 and fbdev drivers.

Hi Hardik Shah,

I tried with that binaries. But syslink.ko is not inserting. Can you tel me the version syslink.ko in the PSP14 package.

I am using the kernel release 2.14. Please tell me any solution. In user guide they had given to use Syslink_02_00_04_83 . But I don't have the source code. can you tell me where I can get the source code of aboversion syslink.

Thanks in advance.

Hi,

Are you getting the same crash log? You have slaveloader and syslink binaries right. Any specific need for syslink. Syslink releases could be found at http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/syslink/index.html. You are following exactly same steps as mention in userGuide of video driver right? No modification is done to any of the driver right?

Hi Hardikshah,

Yes I had binaries and following the same procedure what are all given in the user Installation guide. I didn't modify anything in the driver. But I need to know whether syslink is required to insert vpss.ko, ti81xxfb,ti81xxvo modules.

0 HardikShah over 13 years ago in reply to Muhammad Salih

TI__Mastermind 20245 points

Yes,

You need to insert syslink.ko for inserting vpss.ko and loading slaveloader. Video driver userGuide clearly says this @ http://processors.wiki.ti.com/index.php/DM816X_AM389X_VPSS_Video_Driver_User_Guide_PSP_04.00.01.14#Load_VPSS.2C_Fbdev.2C_V4L2_Display_and_V4L2_capture_Driver_Modules

Please follow exactly what is there in userGuide and use released binaries only. Once you are up and running you can do changes and write applications as you require.

Hi Hardishah,

I had tried the same procedure with syslink version of 2_00_04_83. In this case also i am getting the same problem while inserting vpss.ko. Can you tell me what is the problem

Thanks in advance.

Hi,

I think you are missing some step. This is because PSP14 is tested here and many people are able to bringup applications based on that. Can you please send me dump console log. Start logging once you boot system till you see crash. Insert all modules with debug=1 like insmod vpss.ko debug=1. Lets see what is the problem.
