Bus Blaster JTAG debugger / Re: BusBlaster v3c setup problem on linux
Yes, I've been using the sudo.

After doing more digging, this may be an openocd problem.  I have tried this with two different pandaboards, ES revision B1 and B2.  I have tried using both the ti_pandaboard.cfg and ti_pandaboard_es.cfg files.  However, the omap4460.cfg file has a bug in it:

Code: [Select]
target create $_TARGETNAME cortex_a -chain-position $_CHIPNAME.dap 
  -coreid 0 -dbgbase $_dbgbase 

The value "cortex_a" is invalid and when you run openocd, it will give the following error:

Code: [Select]
Runtime Error: embedded:startup.tcl:20: Unknown target type cortex_a, try one of
 arm7tdmi, arm9tdmi, arm920t, arm720t, arm966e, arm946e, arm926ejs, fa526, feroceon, dragonite, xscale, cortex_m, cortex_a8, cortex_r4, arm11, mips_m4k, avr, dsp563xx, dsp5680xx, testee, avr32_ap7k,  or hla_target

This bug has been prevalent in many such config files and people have just gone in an set it to cortex_a8.  However, the OMAP 4460, used by the pandaboard es models, is a cortex_a9 processors, not a cortex_a8.  If this is the case, the omap4460.cfg file is useless as it doesn't contain the correct values, which would definitely explain the problems I am having.

Bus Blaster JTAG debugger / Re: BusBlaster v3c setup problem on linux
I have now tried two bus blaster boards, three different machines, and eight different sets of "setup" instructions, and I still can't get this to work.  I am making one last attempt with a Windows XP VM.  If that doesn't work, tincantools it is.

Bus Blaster JTAG debugger / Re: BusBlaster v3c setup problem on linux
I actually started over and tried setting this up on a new machine (my original was an offline machine with a somewhat old ubuntu repository) and I'm much further along now, but I'm still running into errors.  When I run my openocd command now, here's what I get:

Code: [Select]

Error: unable to open ftdi device: device not opened
Error: ListDevices: 2
Error: 0: "Dual RS232-HS A"
Error: 1: "Dual RS232-HS B"
in procedure 'init'

I checked dmesg again as saw that it still shows 'Detected FT2232H", so I tried changing my cfg file to 'interface ft2232h' just to see what would happen.  When it did that, it showed an error but printed the available interfaces.  It states:

Code: [Select]
Error: The specified debug interface was not found (ft2232h)
The following debug interfaces are available: 
1: ft2232

Given that, I have to assume the driver is working and that the computer is detecting the bus blaster.  Any ideas?

Bus Blaster JTAG debugger / Re: BusBlaster v3c setup problem on linux
Yes.  I'm just using the default bus blaster configuration file that comes with the openocd source code.

Code: [Select]
interface ft2232
ft2232_device_desc "Dual RS232-HS"
ft2232_layout jtagkey
ft2232_vid_pid 0x0403 0x06010

I'm attempting to include some additional information, but the website says my "post looks too spumy for a new user, please remove off-site URLs", even though I have no URLs in my reply.  So I'll leave this post like this and add a few more comments with the remaining information.

Bus Blaster JTAG debugger / BusBlaster v3c setup problem on linux
I'm running Ubuntu 12.04 and am attempting to connect to a pandaboard via the BusBlaster v3c and am having no luck at all.  I installed the libftdi1 driver on my system and I can confirm that the devices is showing up.  'lsusb' shows the device, and running 'dmesg' shows the OS picking up the new board.  However, when I attempt to run openocd, I'm getting the following error:

Code: [Select]
Error: The specified debug interface was not found (ft2232)
The following debug interfaces are available:
Runtime error: tcl/interface/busblaster.cfg:11
in procedure 'script'
at file "embedded:startup.tcl", line 58
in procedure 'interface' called at file "tcl/inteface/busblaster.cfg", line 11

I am invoking the application with the following command (from inside the openocd source directory): openocd -f tcl/interface/busblaster.cfg -f tcl/board/ti_pandaboard.cfg

I first install openocd via apt-get and tried that with the same error.  I also tried compiling it from source and got the same error.  Running lsusb displays the following:

Code: [Select]
Bus 002 Device 005: ID 0403:6010 Future Technology Devices Internation, Ltd FT2232C Dual USB-UART/FIFO IC

dmesg shows the following:

Code: [Select]

usb 2-1.2: New USB device found, idVendor=0403, idProduct=6010

usb 2-1.2: Manufacturer: FTDI
ftdi_sio 2-1.2:1.0: FTDI USB Serial Device converted detected
usb 2-1.2: Detected FT2232H

Any ideas?
