Tool/software: Linux
I was creating my own uboot, linux kernel and rootfs based on the ti-processor-sdk-linux-am335x-evm-04.03.00.05. Kernel was built based on tisdk_am335x-evm_defconfig with additional configs (via make menuconfig)for Ethernet over usb (for usb0 i/f) support. I also created a rootfs with all kernel modules installed to it, all went well.
I then created a bootable SD card with the images created above and was able to boot successfully on a BBGW reference board. However, the usb0 interface did not get enumerated during startup.
I can manually load the kernel modules to make usb0 available and get it configured but I can’t ping to the host from it. Is there anything missing here? What else is needed?
A console log is attached.
Thanks,
Mike
