Howdy,

I realize time has passed on the Blackboard products, but I was wondering if there was a way to use the Blackboard Nano, with the latest Arduino support package.

The device is no longer a selection, and choosing the Redboard Nano errors out.

Thanks,

Randy

Just a short addendum ...

I can see right where the bootloader python script is choking ... lots of cool features, auto-bauding etc.

def wait_for_packet(ser):

packet = {'len':0, 'cmd':0, 'data':0, 'crc':1, 'timeout':1}

n = ser.read(2) # get the number of bytes
if(len(n) < 2):
return packet

packet['len'] = int.from_bytes(n, byteorder='big', signed=False) #
payload = ser.read(packet['len'])

if(len(payload) != packet['len']):
return packet

packet['timeout'] = 0 # all bytes received, so timeout is not true
packet['cmd'] = payload[0] # cmd is the first byte of the payload
packet['data'] = payload[1:packet['len']-2] # the data is the part of the payload that is not cmd or crc
packet['crc'] = get_crc16(payload) # performing the crc on the whole payload should return 0

File "C:\Users\randa\Desktop\Sparkfun Artemis\toolchain\Arduino_Apollo3-master\tools\artemis\artemis_svl.py", line 132, in wait_for_packet packet['cmd'] = payload[0] # cmd is the first byte of the payload

Thought about this a few days, and reasoned since the Artemis Nano Blackboard was a beta release, the fundamental software should/could be different.

So I decided to test the factory Ambiq boot loader option in the Arduino IDE, at a reasonable baud-rate.

Voila! (I'm rather disappointed that someone form Sparkfun didn't field this easy to answer issue, are they monitoring this forum?)
