pirx 0 Report post Posted October 25, 2013 Hi, I've been developing Papilio apps on my Macbook Pro. It has beenworking great so far. Normally, I run ubuntu under vmware and downloadbit files using papilio-prog. Yesterday, I upgraded to Maverick. Unfortunately, now I can't seem to get papilio-prog to work. If I run itI get the following error. % papilio-prog -cCould not access USB device 0403:6010. I recompiled the source, and I get basically the same message. I alsotried it using sudo. I looked at /dev and now I get the following devices. cu.usbserial-00001014Bcu.usbserial-141Atty.usbserial-00001014Btty.usbserial-141A I think this has changed, but I can't remember what it used to show. Any suggestions? Share this post Link to post Share on other sites
Jack Gassett 0 Report post Posted October 25, 2013 Oh boy, I just released an installer and tutorial for Mac OSX, and now its not working for Maverick... Can you give the installer a try and see if maybe it does work under Maverick?http://gadgetfactory.net/learn/2013/10/25/install-papilio-loader-on-mac-osx/ Jack.

pirx 0 Report post Posted October 25, 2013 I downloaded the Mac Installer. Installation worked fine. But the programmer still can't access the device. Here is the message I get. Could not access USB device 0403:6010. If this is linux then use sudo. I tried it from the GUI and from the command line. On the command line, I triedit with sudo. None of these attempts worked.

pirx 0 Report post Posted October 25, 2013 Good idea. I tried my Arduino and that worked. It uses an FTDI chip, but probablya different ftdi driver stack. Pat Share this post Link to post Share on other sites
Jack Gassett 0 Report post Posted October 25, 2013 Well, that is a good piece of the puzzle... It brings up another question though, are the virtual COM ports of the Papilio working? Can you load a bit file that outputs something over the serial port and see the output? This may be a catch 22 for you though. Jack. Share this post Link to post Share on other sites
pirx 0 Report post Posted October 26, 2013 I'm away from my mac the next couple of days. I will look into that when I get back. Although,as you say, it may be tricky to do without a connection. Share this post Link to post Share on other sites
pirx 0 Report post Posted October 31, 2013 I think I figured it out. Mavericks now loads the FTDI drivers by default. In order to use libftdi, you need to unload thedriver. Here is what I did: sudo kextunload -v -bundle com.apple.driver.AppleUSBFTDI There may be another way to do this. I haven't tried the serial port yet.

tomdehavas 0 Report post Posted December 1, 2014 Hi I had the same problem, "Could not access USB device 0403:6010. If this is linux then use sudo" it was intermittent. Rebooting the computer seemed to help but it would fail after 10 mins or so. I found this forum and twoothers and tried the recommendations to no avail but then found at the end of this forum; http://embeddedprogrammer.blogspot.co.uk/2012/07/hacking-ov7670-camera-module-sccb-cheat.html The conclusion that the cable was the problem. I replaced my cable with a shorter one and it all worked! :-) Share this post Link to post Share on other sites
Jameson 0 Report post Posted October 12, 2015 I've updated my last forum post on how to have the programmer and serial port active simultaneously (http://forum.gadgetfactory.net/index.php?/topic/1148-butterflyloader-on-macosx/?p=17129). This thread looks a bit old so I assume OP may not care anymore, but I'm posting here in the hopes that it'll will help anyone who lands here from google.
