Thanks for your input Ketul.
I totally agree that printf is usually enough. That does require a
'special' cable (serial TTL logic levels to usb) but is worth it. JTAG
also requires a
If you can, consider a beaglebone white - it has the UART and JTAG on
the regular USB port (the one it already takes power from), an ideal
development board with the same SOC as the BBB.
