Finally I decided to move to ARM architectures, and I have bough a Olimex LPC-2378-STK board and a Olimex ARM-USB-TINY emulator. Recently I received both and here started my problems. I have installed the Eclipse + GNUARM + OpenOCD environment included in the CD provided with Olimex, downloaded a test program from [here, modified the OpenOCD configuration file and I have made a lot of tests, but I can’t get the board to work. Every time I try to program the flash I get this message fro OpenOCD:
Info: openocd.c:93 main(): Open On-Chip Debugger (2007-09-05 09:00 CEST)

The “funny” thing is that even when I unplug the ARM-USB-TINY from the USB Bus, I still get the “Unknown LPC Variant” messages:

# Software may later switch to one of the other available clock sources."
# "The nominal IRC frequency is 4 MHz."

# oder gar 14768 weil ISP schon irgendwas gemacht hat?
# oder PLL aus und umschalten auf IRC -> schein nicht richtig zu klappen...

When I try to flash the program, the ARM-USB-TINY LED blinks a little bit, and the board wakes from reset, but nothing else happens.
I’ve tested a lot of things: changing jtag_speed, changing ft2232_device_desc from “A” to “B”, changing jtag_nsrst_delay and jtag_ntrst_delay, I have reinstalled the dev environment from the ground up following James P. Lynch guide, I have also tested WinARM, and a lot of things I don’t remember now, but always get the same result :(. I’m starting to think maybe something in the board or the emulator is wrong.
Please help! Any suggestion would be really appreciated!](http://www.siwawi.arubi.uni-kl.de/avr_projects/arm_projects/)
