Hi,
Recently I am engaged in the work of add the ov7670 driver to L138 evm board .The figure below shows a block diagram of the system. Motherboard is LOGIC L138EVM board,I design a daughter board connect to the pin of J29 . The daughter board connect a OV7670 camera as the Video Input.
The main file In dvsdk_ompla38-evm_04_03_00_06 Software Development Kit I modify is :
First: add the ov7670 driver when make menuconfig.
Second: modify the board initialization file of board da850-evm.c add the ov7670 struct information to replace the mt9t031 camera infomation.
Third: modfiy the psp/linux-2.6.37-psp03.21.00.04.sdk/drivers/media/video/davinci/vpif_capture.c
file function of
static __init int vpif_probe(struct platform_device *pdev) to register the ov7670 device.
But when I loaded the modified kernel into board ,it comes follows error ,the log is follows,
we cannot register the ov7670 device successfully .could you explain it or how to make the ov7670
camera work with the L138EVM .
Thanks very much.
