Error in using kernel module linux-2.6.37-psp04.01.00.06.patch2

Hi,

I am using ezsdk_5_03_01_15 and linux-2.6.37-psp04.01.00.06.patch2 and using omx-ti81xx-src_05_02_00_30 on TI-J4 EVM(TI8148) .

We have kernel module in our framework which internally calls OMX. In this module I am trying allocate shared memory(0xB0000000), and facing error "Device or resource busy".

But If I use the same shared memory(0xB0000000) in OMX test application(iL Client), its working fine.

I found from kernel prints that allocate_resource kernel API fails. Is there any changes in this kernel release .. ?, related to resource allocation etc.

And I also observed that the same set-up i.e. same framework module using (0xB000000) built with earlier versions of kernel viz. linux-2.6.37-psp04.01.00.05.patch1, happening successfully.

Please can any one provide me Info regarding changes in kernel linux-2.6.37-psp04.01.00.06.patch2.

Hi,

There is no change in kernel version or any of the kernel components between .patch1 and .patch2 release. .patch2 adds V4L2 capture driver support on top of .patch1

Hi Hardik,

One more clarification:

We tried with without any patches being applied to linux-2.6.37-psp04.01.00.06 package.

We still observe the same behavior. We need to know the difference between linux-2.6.37-psp04.01.00.05 and linux-2.6.37-psp04.01.00.06

Regards,

Shashikiran
