DLPC4420AEVM: problem of load this board?

jianwei zhang

Part Number: DLPC4420AEVM

hello! I just purchased the DLPC4420AEVM development board here. The first time I prepared to power on and load the firmware, I couldn't load it later. What's the problem? Is it due to the lack of underlying drivers in the development board or other reasons?

Yes,I follow step by step in the DLPC4420AEVM User's Guide,When the DMD board is not inserted, the USB can be connected normally. But when inserting the DMD board, it cannot be connected. Moreover, the voltage of DMD power supply is normal，How to solve it？（SW1 turned on, the logo appears and disappears after a moment ）

What DMD board are you using with the DLPC4420AEVM?

Can you please provide the oscilloscope measurements on the DMD power up sequence?
