Greetings all,
I’ve built my OpenOCD and requisite drivers (I think) but still cannot get the Olimex tiny to recognize. lsusb cites the device as being there, but there’s no identifier string, just the VID and PID. I’ve downloaded the direct driver from ftdi (0.4.13) and followed their instructions to the letter, but with no luck.
I should have got the other one! I didn’t know this one was going to raise compatibility issues. Has anyone got this thing to work under linux?
You’re most likely lacking the appropriate permissions to the USB filesystem. Both FTD2XX and libftdi internally rely on libusb which uses the USB filesystem to talk to the hardware from userspace.
Normally you’d use udev to automatically set the required permissions depending on the VID/PID of your USB device.
On my system I have a “/etc/udev/rules.d/45-ft2232.rules” with the following content:
BUS!="usb", ACTION!="add", SUBSYSTEM!=="usb_device", GOTO="kcontrol_rules_end"
SYSFS{idProduct}=="6001", SYSFS{idVendor}=="0403", MODE="664", GROUP="usb"
SYSFS{idProduct}=="6010", SYSFS{idVendor}=="0403", MODE="664", GROUP="usb"
SYSFS{idProduct}=="cff8", SYSFS{idVendor}=="0403", MODE="664", GROUP="usb"
SYSFS{idProduct}=="bcd9", SYSFS{idVendor}=="0403", MODE="664", GROUP="usb"
SYSFS{idProduct}=="bca0", SYSFS{idVendor}=="0403", MODE="664", GROUP="usb"
SYSFS{idProduct}=="bdc8", SYSFS{idVendor}=="0403", MODE="664", GROUP="usb"
SYSFS{idProduct}=="0003", SYSFS{idVendor}=="15ba", MODE="664", GROUP="usb"
SYSFS{idProduct}=="f1a0", SYSFS{idVendor}=="0403", MODE="664", GROUP="usb"
LABEL="kcontrol_rules_end"
Thanks for the help! I’ll get this eventually.
Tried adding the rules to my udev rule set, but with no luck. I used your rules, and added one, since the PID of the arm-usb-tiny is 0x04 not 0x03, reloaded the rules, (even rebooted as a last ditch effort) with no luck.
dmesg spits out a message that says the device is there, but “is not claimed by any active driver”
I modprobe ftd* in an effort to get the ftdi driver to load, and I get the ftdi_sio and usbserial driver in my lsmod, but still no driver to claim the ARM-USB-TINY
I know there’s something simple I haven’t done here, any thoughts?
I guess one good question would be: Should I be using libftdi, or the direct driver from FTDI for linux? I’ve got both and installed them, but I’m not sure which is active, if either. Here’s the relevant output from /proc/bus/usb/devices:

And here’s the error I get from openocd when I compile it with the libftdi driver:

I’m grateful for any advice. Sorry for the flood of info!

Your ft2232_device_desc is wrong, I guess:
Change
ft2232_device_desc “Olimex OpenOCD JTAG A”
to
ft2232_device_desc “Olimex OpenOCD JTAG TINY A”
or
ft2232_device_desc “Olimex OpenOCD JTAG TINY”
The “A” shouldn’t be necessary on Linux, but apparently your FTDI driver uses it.
The “ftdi_sio” module is only required when using the secondary channel of the FT2232 as a UART (not possible on the tiny, afaik).

That did it! Thanks!
