mini2440+openJTAG+openOCD

[Klets]

Hello,
I'm trying to run one of examples from CD (which was in the box with mini2440), but have problems. I'm using XSCALE ARM JTAG USB Emulator+openOCD+eclipse+GNUARM.
After succesfull building example project "leds", I'm run through eclipse openocd with next script:
