Hello all,

I am using openOCD 0.4.0. The things that I have is below;

Eclipse IDE,(helios)

A lpc2148 cpu board(uni-ds3 board from mikroelektronika),

ARM-USB-OCD (Olimex) JTAG dongle

all the steps like this;

1- First of all the board can be programmed by using openOCD4.0 with the eclipse.

2- And everythins are ok.

3- When the Hex code transferred to the board again, im getting following error from the console in eclipse.

And the board can not be programmed again…

If i use openOCD + Telnet ,i am getting error again below;
