Tool/software: Linux
I have a Beaglebone black and I am trying to build a custom Os using buildroot. I am using the default configuration provided for beaglebone using the following command:
make beaglebone_defconfig make
I am following this link as a guide.
I have an Sd card and I have created 2 Partitions.
The Partition 1 is a boot partition and partition 2 is a rootfs partition.
Partition 1 is created using the following command:
sudo mkfs.vfat -F 32 -n boot /dev/mmcblk0p1
and it is of size 128Mb. Partition 1 consists of the following files:
- MLO
- uEnv.txt
- u-boot.img
- zImage
- am335x-boneblack.dtb
Partition 2 is created using:
sudo mkfs.ext4 -L rootfs -E sdcard /dev/mmcblk0p2
Now when I boot the Beaglebone using Serial console I get following logs:

I am unable to understand Why my kernel can detect the ethernet but, not the USB port?
What kernel configurations or other configurations are required to detect the USB port for buildroot?
