Good Day.
Please, tell me
We are now using a video camera developed on the basis of a Denebola reference board (CX3 and OV5640).
But our quartz oscillator (RefClk source) has a frequency of 27 MHz, and not 19.2 MHz as in Denebola. Other quartz is analogue as Denebola.
Tell me. What exactly should be changed in the source code in order for everything to work correctly?
Mipi settings ? How ? What value ?
I2C, SPI settings ?
PLL ?
Many thanks.
Solved! Go to Solution.

Hello,
Please configure CX3 using the same parameters in the screenshot below.
Ensure that your project inlcludes the library ov5640.a

Dear,
Anything similar to this?
// Configuration parameters for VGA for the OV5640 sensor
CyU3PMipicsiCfg_t cfgUvcVgaNoMclk_HS = {
CY_U3P_CSI_DF_YUV422_8_2, // dataFormat
1, // numDataLanes
0x1, // pllPrd
90, // pllFbd
CY_U3P_CSI_PLL_FRS_125_250M, // pllFrs
CY_U3P_CSI_PLL_CLK_DIV_2, // csiRxClkDiv
CY_U3P_CSI_PLL_CLK_DIV_8, // parClkDiv
0x00, // mclkCtl
CY_U3P_CSI_PLL_CLK_DIV_8, // mClkRefDiv
640, // hResolution
0x01 // fifoDelay
};
PLL settings ?
Only in this place?
Nowhere else?
Many thanks.
Doesn't it make it difficult for you to send a ready-made configuration file?
At least for modes 640*480 for connections USB2 and USB3 ?
I can't make MIPI calculator work ...

Yes, many thanks.
But I not understand, how I can compile its configuration file and add it (or replace old file) for apply new 27 MHz settings ?
Please, tell me.
