Abstract
A microchip includes a central processing unit (CPU) configured to execute a software application. The microchip further includes an Ethernet interface configured to transmit Ethernet packets to and receive Ethernet packets from an external debugging entity. The microchip further includes an on-chip debug and trace module configured to transform debugging data and trace data from the CPU into a stream of Ethernet packets, and to provide the stream of Ethernet packets to the Ethernet interface for transmitting the stream of Ethernet packets to the external debugging entity.
