Has anybody got a usb jtag working in Gentoo, who could give me some
handy tips.


The device I have is an Amotec JTAGkey-Tiny which is based on a FTDI
FT2232 USB device.


I have tried to follow the Amotec documentation, but is oldish and not
completely logical.


It all works on WinXP (using VirtualBox) but as it uses gdb I would like
to use Gentoo only.



Many thanks

I use a similar device based on the same chip.

completely logical.

The following works for me:

~
[jason@phoenix] $ find /lib/modules/`uname -r`/ -name "*ftdi*"
/lib/modules/2.6.26/kernel/drivers/usb/serial/ftdi_sio.ko
~
[jason@phoenix] $ grep -rni ftdi /usr/src/linux/.config
1693:CONFIG_USB_SERIAL_FTDI_SIO=m
1754:# CONFIG_USB_FTDI_ELAN is not set

It should auto-load when you plug the cable in. Then udev will create
/dev/ttyUSB0 .

Make sure you have support built into the kernel on the Gentoo
development hosts.

something like this:
make menuconfig
--> device drivers
--> usb support
--> usb serial converter support
--> USB FTDI Single Port Serial Driver

'lsusb' should show something like this:

#lsusb
Bus 001 Device 001: ID 1d6b:0002
Bus 006 Device 001: ID 1d6b:0001
Bus 004 Device 003: ID 0403:6001 Future Technology Devices
International, Ltd FT232 USB-Serial (UART) IC



One you have it hooked into your kernel,
Then follow the vendor stuff.


hth,

James

i havent used that particular device, but the "urjtag" package
(with "libftdi") works just fine with another FT2232 USB device (the gnICE).
no need for kernel drivers.

Thanks for the replies.

Jason & James you are writing about the normal ftdi usb-serial drivers,
which I already use for other things.
Mike is correct.

Just in case anybody else searches here is what I did to get it working.

get driver, libftd2xx0.4.13.tar.gz and extract.
get openocd from respository, svn checkout
svn://svn.berlios.de/openocd/trunk/openocd and extract
copy ftd2xx.h & WinTypes.h from driver tar to trunk/src/jtag
copy libftd2xx.so.0.13 to /usr/local/lib & sym link to libftd2xx.so &
libftd2xx.so.0 also create sym links in /usr/lib
in trunk directory
./bootstrap
./configure --enable-ft2232-ftd2xx
make then su to make install
get insight and untar (cannot emerge for arm debugging)
create directory to configure into then
../insight-6.8/configure --target=arm-elf --prefix=/opt/insight-arm
make then su to make install

to run:
openocd -f/pathtoconfigfile
it returns the jtag device found

now run /opt/insight-arm/bin/arm-elf-insight and connect to target on
localhost:3333

I am now able to debug ADuC chips, have not tried loading flash with
this yet.

Thanks for the info, Billy. Maybe this little bit of prose could be
added to the gentoo documentation? I think it would be great to list
JTAG devices/boards/processors that folks have gotten to work with
embedded Gentoo....


just a thought,

James

meh ... it'd be duplicating the lists available at the respective upstream
projects (openocd and urjtag) ...

why ? we have an openocd-9999.ebuild which fetches straight from the upstream
site ...

Just tried to emerge it. Here are two small patches to the ebuilds to
make it compile on amd64.

Let me know if it looks good and I'll hit bugzilla.
