2010-11-30 15:44:42     Problems with urjtag and ICE-100B

Hi, I have an ICE-100B and BF-527 Ez-Kit board and am having problems with the urjtag tools. The ICE-100B works fine with Visual DSP.

 

I've tried it on a Linux box running Ubuntu. I downloaded blackfin-toolchain-2010R1-RC4.src.tar.bz2 and built the jtag tool.

Running ./jtag from src/apps/jtag, and then 'cable probe' gave this (same for 'cable ICE-100B):

Found USB cable: ICE-100B

Error: usbconn/libusb.c:239 usbconn_libusb_open() libusb error: libusb_claim_interface failed: -1

 

I also tried the Windows version (on XP) from the latest snapshot - blackfin-toolchain-win32-SVN.exe - SVN-20101128. I did the modification to the .inf file as an earlier poster described.

 

I ran bfin-jtag.exe and "cable probe". This said "Found USB cable: ICE-100B, ICE-100B Firmware Version is 2.0.0.", but on repeating this command it said the version was 0.0.1 and needed upgrading. On a third run it said (after some delay): "do_host_cmd: unable to read from usb to &results: -7;wanted 2 bytes but only received 0 bytes", and then complained about version 0.0.1.

 

The firmware version has already been upgraded as described. Any help will be appreciated (with either Windows or Linux version). Thanks.

did you grant your user under linux proper permissions to the usb devices ?  try running it as root to see if that's the problem.

 

the Windows bug is known.  for now, just dont do that.

That was it, thanks!  All working now (on Linux).
