P4 + 3rd party USB<->Serial connector (PL2303)

Post by hamletbon » Sun Jan 18, 2009 10:30 pm

OK, at the end I purchased a P4, and few RBBB board. The connection is like this
USB->PL2303->P4->RBBB/BBB

Sadly, it doesn't seem to work, when I tried to upload the program from my laptop, pin 13 just keep blinking as the initial state and nothing is being upload. Arduino complaining that the programmer is not responding.

Any idea?

Please check the latest P3/4 docs on the website for connecting the P4 to the BBB. There is an issue because the cable header doesn't power the P4. There are three workarounds for this in the docs. So maybe try this first with the RBBB. If you get things working there, then move on to BBB.
