Connecting to a device

Note:

For programming the board, you can pick either target. The CPUs share the same memory

space. Programming either CPU programs both CPUs. However, if you are debugging, this

choice matters. The debugger will see only the CPU you connect to. These instructions do not

use the debugger

2.

Program the board
Choose Debug > Program to program the device with the project, as

shows
