Hello everyone! I'm embedding i.MX6 in my apprication which uses a camera, so I'm trying to research about CSI interface. CSI use csi_hclk, ipg_clk, ipg_clk_s, and ipg_clk_s_raw clock; they are from AHB_CLK_ROOT and IPG_CLK_ROOT, IMX6SLRM Reference manual says that they are Module clock, Peripheral clock, Peripheral access clock, and  Peripheral  raw data clock, but the manual doesn't tell enouth description about them. Which clock is the sampling clock of pixcel data? how fast should i set each clock for my camera?; my camera emits 75.4MHz data clock.

Thank you for reading this.

 

Regards,

Ichimura Shinichi
