[SOLVED] aqemu-connecting to JTAG via usb

Phorize · 03-04-2012, 09:17 AM

Im am running a laptop with slackware64 13.37 with aqemu/qemu for virtiualisation.

I want to connect from the ubuntu vm to a jtag via usb. my host usb ports are:

Code:

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub                                
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub                                
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 003: ID 04f2:b1b4 Chicony Electronics Co., Ltd Lenovo Integrated Camera
Bus 004 Device 002: ID 0a5c:217f Broadcom Corp. Bluetooth Controller
Bus 003 Device 005: ID 9e88:9e8f

On the aqemu vm I add a select the usb0 as "FTDI SheevaPlug JTAGKey FT2232D B" via a list that I am presented with.

To attach to the JTAG from my laptop usb0 I would normally do:

Code:

screen /dev/ttyUSB0 115200

I boot the vm into ubuntu server and do ls /dev/, The output is in the attached screenshot-I have no idea which device is the JTAG.

Any thoughts? It had occurred to me that this could really be a question about ubuntu, but I wanted to eliminate any problems with the qemu settings first. If I can't trouble shoot this then I'll need to set up openocd on the host and connect from there-openocd on 13.37 is a pain though, as I'm not aware of any slackbuilds for it.

Can't help with the Aqemu/Ubuntu vm/usb problem, but I did build openocd, and its dependency libftdi, successfully on 13.37 using src2pkg when I was messing about with my Sheevaplug. For openocd I used this command:

Code:

src2pkg -e='--enable-ft2232_libftdi --enable-maintainer-mode'

Thanks Brian-I just built the library and openocd using makepkg. It's running ok-now I just have to sort out a uboot upgrade-can't get that working yet though-plug computers are great if you like spending hours chasing around the web looking and reading crap documentation!

My SheevaPlug is <censored>ed up. I've written about it in a few of my LQ blog entries: this is the latest entry.
