Part Number: TMDXIDK57X-LCD
Hello everyone,
I have an am5728 IDK and its camera module is not available, my target is running linux rt 4.9, I am trying to make configurations to use ov7670 via Video Input Port (VIP) connected to j9 connector. this is my camera module:
these are pin connections :
| camera pin | pin name | j9 pin number |
| SIOC | IND_I2C_SCL | 22 |
| SIOD | IND_I2C_SDA | 24 |
| VSYNC | CAM1_VSYNC | 2 |
| HREF | CAM1_HSYNC | 4 |
| PCLK | CAM1_PCLK | 9 |
| XCLK | X1 OUT | pin23 |
| D0...D7 | CAM1_DATA0 ... CAM1_DATA7 | |
| PWON | GND | |
| RESET | 3V3 |
now I can detect the camera using i2cdetect command, but it is not shown in /dev/ directory (as far as I know it should appear as video1, so that I can use it with gstreamer).
this was the original dts file I found in my PSDK on my Host (named am57xx-evm-common-cam-mt9t111.dtsi):

I changed it to:

I compiled the dts using dtc and replaced the output dtb on my target with its equivalent, but still, nothing appears in /dev/. I also tried some other configuration but none of them were successful.
I was wondering if someone could explain the changes I have to make in the device tree (or maybe drivers) so that my target IDK can detect my camera module.
B.R,
Alex.
