We’re desperately trying to get the JTAG Tiny to work with a LPC2387 based board on Linux. We had given up on OpenOCD 0.1 and just gave it another few hours trying with OpenOCD 0.2. It just doesn’t work… altough this JTAG seems to work for other people.
We are using 32bit Ubuntu Linux with the current kernel (2.6.28-15-generic). OpenOCD has been configured with --enable-ft2232_libftdi --enable-verbose-jtag-io --enable-verbose.
This is what it says:
Open On-Chip Debugger 0.2.0 (2009-08-25-16:51) Release
$URL: http://svn.berlios.de/svnroot/repos/openocd/tags/openocd-0.2.0/src/openocd.c $

Error: couldn't read the requested number of bytes from FT2232 device (19 < 81)
Error: couldn't read from FT2232
Error: number of discovered devices in JTAG chain (0) does not match (enabled) configuration (1), total taps: 1
The number of bytes that could be read varies.
I have veryfied that JTAG is correctly listed using lsusb:
idVendor 0x15ba Olimex Ltd.
idProduct 0x0004 OpenOCD JTAG TINY
bcdDevice 5.00
iManufacturer 1 Olimex
iProduct 2 Olimex OpenOCD JTAG TINY
Any hints?
