Linux/TMS320DM8148: vpss fail lead to DSP CORE interrupt disable

Hi,

Which software release are you using?

Regards,

Pathpartner Technology Pvt Ltd.

I use the linux kernel-2.6.37-psp4 come with the EZSDK-5.05, SYSLINK-2.02.
An Ubuntu 12.04 for arm (armel) is used for system.

Hi Biao Yang,

I am not verymuch familiar with DM8148 EZSDK.
However, we can look into the issues if you can post complete logs starting from the boot till you face the error.

Thank you for you concern! I had fix the problem! I had fix the problem by change the vpss init script!

I upload the log and the script (new fixed ,and old problem version in one file ). holp you can figureout the source of the problem.

I think the interrupt handleing code had some bug. It case the ext int  blocked for a long time both in ARM and DSP.   

I found that when I insert a USB disk  , the same problem (ext INT blocked) happend in DSP core.  I had to warning  the user no to do USB Insert and file copy when the board working
