Hi, All: If users want to debug UDK BIOS source code, they could use COM port or USB port as communication channel. Usually, UDK suggests using Ajays NET20DC device as the usb port inter-connection cables between Host and Target board. But, I found: Ajays is bankcrupt so their product line is end of life (EOL). So, is there any other suggestions? Is there other alternative usb debug cable? Thanks ????? ?????????????????????????????????????????????????????
