Hello Bin,
Now I am seeing another issue , the USB3.0 port (bottom) is not working. I am sure that both ports are working fine with UEFI Firmware. I tested by connecting a mouse to the USB port , in the USB2.0 port (upper) it is working fine but in the USB3.0 port the mouse is not getting detected. I am not sure why it is happening. I looked into the kernel logs but I didn't get any error/debug messages. Can you please check this on your board also.
Do you mean xHCI is not working under U-Boot? xHCI is not enabled in U-Boot yet. IIRC, U-Boot's xHCI driver does not support Intel controller yet.
No, The USB port is not detecting any devices. In the board only the upper USB port detects the hardware like USB-mouse and USB-keyboard ., The lower port is not detecting any hardwares. Ya I am seeing that eXHCI driver being used, but atleast both ports should detect the USB 2.0devices.
In the minnowmx.h file the maximum controller count is defined to be 1. May I know what it corresponds to?
#undef CONFIG_USB_MAX_CONTROLLER_COUNT #define CONFIG_USB_MAX_CONTROLLER_COUNT 1
Thanks & Regards, Vinothkumar
