hi,
i have DRA74x Jacinto 6 Board.i want to interface my camera into VIP port.but when i connected my camera and checked its not working for me. i followed the steps below :
Capturing through TVP decoder
Linux kernel supports TVP5158 NTSC/PAL decoder.
TVP5158 decoder is a TI chip which can decode upto 4 channels of NTSC/PAL analog video and multiplex it.
Video capture from 1 channel TVP5158 can be verified as follows.
- Connect analog camera to the Vin1 port of the JAMR3 board
- Change the SW2 switch setting on JAMR board as SW2[1-2] = [OFF, ON] - This is to select i2c4 for the IO expander
- Reboot the board and enable i2c2 as given above
- I2C device on Bus 2 slave address 0x58 should be probed successfully
- VIP should register a V4L2 video device (e.g. /dev/video1) using this i2c device
- Run dmabuftest with capture format of the analog camera (e.g. '720x240@YUYV')
Here am not using GLSDK.through kernal configuration(3.14) am modifying.when i checked with" /dev " i couldn't find anything related to i2c4 or V4L2. please help me regarding this.
regards,
Niranjan B
