i.Mx6 CSI Test Mode Question

The customer would like to test BT.656 using Test mode. Is it supported?

  1. 38.4.3.3 Test mode in RM shows only one CSIx_SENS_CONG setting. Does it mean Test mode support only one as follows?

Does Test mode support other settings?

CSIx_EXT_VSYNC = 0x1

CSIx_DATA_WIDTH = 0x1

CSIx_SENS_DATA_FORMAT = 0x0

CSIx_PACK_TIGHT = 0x0

CSIx_SENS_PRTCL = 0x1

CSIx_SENS_PIX_CLK_POL = 0x1

CSIx_DATA_POL = 0x0

CSIx_HSYNC_POL = 0x0

CSIx_VSYNC_POL = 0x0

For example,

customer want to know if Test mode support  CSIx_SENS_PRTCL=0x2or 0x3 instead of 0x1?

customer want to know if Test mode support CSIx_SENS_DATA_FORMAT=0x1or 0x2 instead of 0x0?

Answer:

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.
