S32v234 access 4 channel OV10640 problem

435761040 — Wed, 22 Aug 2018 08:37:46 GMT

I refer to the ISP tutorial to modify the ov10635 four-way camera tutorial
Mainly to replace OV10635 with OV10640

Added in main.cpp

After the compilation is finished, move the generated .elf to S32V234 and the result seems to crash. Show OAL initialization error?

Even if I commented out OAL_Initialize() in the main.cpp code, I reported the same error.

Have you encountered this kind of problem?

Hi,

What is your target linux version?

I am following the main.cpp generated by the ISP tutorial settings.

/*
* main implementation: use this 'C' sample to create your own application
*
*/

#include "oal.h"
#include "isp_gen.h"
#include "isp_user_define.h"
#include "ov10635_surround_c.h"
int main(int, char **)
{

/* OAL initialization */
OAL_Initialize();
/**********************************************************************

**********************************************************************/
ISP_CALL();
return 0;

}
/**********************************************************************

void io_config(sdi_grabber *lpGrabber)
{
/* Insert the code to initialize DDR buffers */
sdi_FdmaIO *lpFdma = (sdi_FdmaIO*)lpGrabber->IoGet(SEQ_OTHRIX_FDMA);
SDI_ImageDescriptor lFrmDesc = SDI_ImageDescriptor(WIDTH_DDR, HEIGHT_DDR, RGB888);
lpFdma->DdrBufferDescSet(FDMA_IX_FDMA1, lFrmDesc);
lpFdma->DdrBuffersAlloc(FDMA_IX_FDMA1, DDR_OUT_BUFFER_CNT);

}
/**********************************************************************

void camera_config()
{

}

But it can't be used. Do you need to fill in the functions inside? Where can I find these fills? Configuration of ov10640.
