Hi,
I am working on debugging our customized AM5728 board. I am able to start to boot the kernel. However the kernel crashed during the usb initialization. The booting log is shown as following. Could anyone give me some insight for debugging this problem? Our board is designed based on the AM5728 EVM. I am thinking about this issue is related to interrupt.
