Image sensor test with C6748 LCDK

Xu Xing
Prodigy 140 points

Hi,

I am now using the image sensor test program from the link:

http://e2e.ti.com/support/dsp/omap_applications_processors/f/42/t/200759.aspx

My target image sensor is aptina AR0331 with C6748 LCDK, while the code in the above link is for MT9V032 together with OMAP L138.

I can build the project successfully, but when running it after debug, it always give out the same message "error initializing mt9v032!".

So I dig further into the program, in the "test_image_sensor.c", the VPIF_initReceive pass smoothly, which indicates successful VPIF initialization for the camera mode.

While in the following camera initialization step, the "evmomapl138_mt9v032.c" can not work through the first "I2CGPIO_init(I2C_ADDR_GPIO_UI)", my current conclusion is: this "I2CGPIO_init" is different for LCDK, this is the same case for the following "I2CGPIO_setOutput". 

Could anyone give some advice on how to deal with it on LCDK?

Thanks.

    Hi Xing,

    Thanks for your post.

    Whatever the image sensor test program which you are using is completely validated on EVM board. You should migrate this code to LCDK platform inorder the run the project. It is clearly mentioned in the reply to the below thread:

    http://e2e.ti.com/support/dsp/omap_applications_processors/f/42/t/200759.aspx

    Unless you migrate the source code to LCDK platorm, you will have problem in initializing the peripherals.

    Thanks & regards,
