Is it necessary to change kbi portmode from PCIE to USB？ and how to change it
no need it ! OTG must work in any case
PS : start krescue > KBI - device configure -> … | or from uboot console -> kbi help
still not work， PC cannot recognize the board as a USB device
I have changed dtb for otg mode as follow:
&dwc2_a {
status = “okay”;
/** 0: normal, 1: otg+dwc3 host only, 2: otg+dwc3 device only*/
controller-type = <2>;
};
- check you kernel config
- if something build as module u need use modprobe ??? before use it
PS: show lsmod and zcat /proc/config.gz | grep -e _G_ -e _USB_GA -e _USB_CO -e _USB_F output
There are other problems
I burned this image to the board
linux-image-amlogic-mainline_0.9.5_arm64.deb
linux-dtb-amlogic-mainline_0.9.5_arm64.deb
then reboot it ，PC recognized the device name as WorldCup Device.
but I cant operate it and the HDMI not working properly
check how works HDMI with krescue if it will be ok
just add video=HDMI-A-1:1920x1080@60e to kernel boot args
