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.
