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.
