I have downloaded the Android 7.1 SDK for Firefly-rk3399 and Built it.
I successfully flashed the images on the board.Android got booted up
I enabled the Developer options → USB debugging.
When i connect the USB type-C cable from RK3399 to My PC,
the board does not showup in lsusb details.
anvesh@anvesh:~/firefly-rk3399/kernel$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 413c:2113 Dell Computer Corp.
Bus 001 Device 015: ID 413c:301a Dell Computer Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I have already checked with Android 7.1 firmware image.
I have enabled Developer options in that image.
Still the lsusb can not detect the rk-3399 device.
If it is a hardware problem, then how am i able to flash the images through the same usb port ?
May be the device is in host mode.. how can i check the mode of device ?
please help.
