Hello:
1)In the DLPDLCR4710EVM-G2 system and the schematic diagram provided on the official website, it is found that the J22 pin connecting the optical part has two groups of SPI pins besides the DMD signal. What's the function?

2) In this system, the test power output is normal, the hosr_irq is normal, the DMD control signal is normal, the IIC signal is normal, the USB communication is normal, and the LED is normal, but the GUI test picture is not displayed in the DMD, what may be the reason?
