Figure 9. Arduino interface board connected to the Kinetis board (FRDM-K64F)
As can be observed, there are two USB connectors in the Kinetis boards FRDM-K64F.
See
. The USB connector highlighted in red corresponds to OpenSDA debug
port. This port will be used by the development PC to flash and debug the A71 examples
over an on-board debugger into the Kinetis MCU as well as to have a serial console.
The USB connector highlighted in yellow is directly connected to the K64F MCU and
functionality depends on the example programmed into the MCU.
Figure 10. Red USB indicates OpenSDA debug port. Yellow USB indicates K64F port
(FRDM-K64F)
