We need i.MX6ULL CSI support for BT.656 Interlaced video. Linux version used is 4.1.15.
We have tried the patches supplied in this link : https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/How-to-enable-i-MX6UL-CSI-port-support-B...
But the video is not properly obtained. System hang is observed on using this.
Can you direct us to a working example or patch for this issue?
Hello Kavita_r,
Unfortunately this patch is the only we have and is for 3.14 kernel your L4.1.15 must have this code included; Some suggestion that you may get are:
CSI CM TEST MODE is working as below:
1,only ungated mode.
2,data width should be configured to 8
3,data format should be configured to rgb888
It cannot be other format such as bt656. It uses CSI1_TST_CTRL register to configure {R,G,B} 24 bit value and taking it as RGB888/YUV444 format for further process. The generated image size is due to the configured width & height in the registers.
Regards
