Title: Update CPLD BBv4
Post by: whoami on February 28, 2016, 09:55:28 am
Hi,

I need SWD support for my BBv4. I have found this post http://http://dangerousprototypes.com/forum/viewtopic.php?f=37&t=5954 and I want to try the KT-Link logic.

Now my problem is that I do not know how to do this.
I am working on linux (Arch Linux) and I have installed "libftd2xx" and "urjtag".

My BBv4 is recognized (checked with lsusb).

Using "jtag" on the commandline shows the urjtag implementation.
But now what do I have to do?

"cable FT2232" or "JTAGkey" fails with

Quote
error: Couldn't connect to suitable USB device.
error: ftdi/ftd2xx error: ftdi_usb_open_desc() failed: device not found

And yes I have executed jtag with root privileges.

I have not found any help doing this on linux :(

EDIT 1

Using vid and pid worked ... now I am connected to the ftdi (Connected to libftd2xx driver) :)

Next problem is ... detect hangs forever :( ...
I have set up "bsdl path ." and there is a bsdl file for a xc2c64a_vq100 available. But detect never returns.

EDIT 2

Ok Problem was my USB 3.0 Hub ... connecting the BB directly with an USB 2.0 Port on my tower solved the detect problem. Now it returns with information immediately :)
