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