Our custom design is based on i.MX535.
The design is almost based on Sabre Tablet Design with the peripheral changes alone. We are using Android R10.4 BSP as our reference BSP.
Have interfaced OV7675 Camera sensor via CSI0 interface to i.MX535 similar to the Sabre design.
As per this design CSI0_MCLK pad is used for CSI0_HSYNC functionality.
The only change with respect to Sabre design is that we have used CCM's CSI0_MCLK output @ pad NANDF_CS2 as the Sensor's system clock.
1. As soon as the CCM is configured, I find the clock overriding on the pad CSI0_MCLK (which is to be used as CSI0_HSYNC). Changing this pad configuration also did not help. Have anyone come across this issue? Pls advice how this can be avoided.
2. Why CCM's CSI0_MCLK is not used in Sabre / QSB? Any errata?
