I've been building a Core 3399J carrier-board and I've add the USB OTG port for programming and debugging. I have no issue with the programming part when I boot the board in bootloader mode.
If the board boots properl (Normal boot) the RK3399 is not listed on my USB device when my USB cable is connected. I'm using the TYPEC0 USB DP/DM (USB2 only) on a Standard MicroUSB connecteur. The TYPEC0_U2VBUSDET is pull-up when the USB cable is inserted.

The negotiation seems to not starts to enable the RK3399 to enter in device mode.

let me know if you have and ideal how I can fix this issue.
THanks.

IT인증자격증은 국제적으로 승인받는 자격증이기에 많이 취득해두시면 취업이나 승진이나 이직이나 모두 편해집니다. 다른 사람이 없는 자격증을 내가 가지고 있다는것은 실력을 증명해주는 수단입니다. Oracle인증 1Z0-1055-25시험은 널리 승인받는 자격증의 시험과목입니다. Oracle인증 1Z0-1055-25덤프로Oracle인증 1Z0-1055-25시험공부를 하시면 시험패스 난이도가 낮아지고 자격증 취득율이 높이 올라갑니다.자격증을 많이 취득하여 취업이나 승진의 문을 두드려 보시면 빈틈없이 닫힌 문도 활짝 열릴것입니다.
