I have the LPC-H2148 from Olimex and I would like to load the example USB demo to the flash board, using JTAG + OCD. But I was not able to complete all things in order to have everythings working. So, As I am a newbie, I suppose I did something wrong :

My configuration file for openocd is the following :

#daemon configuration
telnet_port 4444
gdb_port 3333

#interface
interface parport
parport_port 0x378
parport_cable wiggler
jtag_speed 0

reset_config trst_and_srst

jtag_device 4 0x1 0xf 0xe
jtag_nsrst_delay 333
jtag_ntrst_delay 333

#target configuration
daemon_startup reset
target arm7tdmi little run_and_halt 0 arm7tdmi-s_r4
run_and_halt_time 0 30
working_area 0 0x40000000 0x40000 nobackup

#flash configuration
flash bank lpc2000 0x0 0x7D000 0 0 lpc2000_v2 0 12000 calc_checksum


It seems that I have no problem to connect to the board, and I try to download the lpc2148_USB.hex file (from the olimex Website) with the following procedure :
> poll
target state: halted
target halted in ARM state due to debug request, current mode: Undefined
cpsr: 0x600000db pc: 0x00000008
> flash probe 0
flash 'lpc2000' found at 0x00000000
> flash erase 0 0 0
> flash write 0 c:\lpc2148_USB.hex 0
wrote file c:\lpc2148_USB.hex to flash bank 0 at offset 0x00000000 in 1s 882707us
> reset run
> poll
target state: running
>

But the moving cursor usb demo is not working...


Any help will be greatly appreciate,
Best regards.

The OpenOCD expects plain binary files, I suppose the .hex from Olimex is an Intel Hex file (an ASCII format). You'll need to convert the file, but I have to admit that I never used ihex before. GNU objcopy should be able to help.
