Hello all,

I have problem with Olimex 2378stk Devlopment board.

Before few days, i tried to debug lpc2378 uart(my first atempt on ARM) throught JTAG.

Everything worked fine, but suddenly debug with eclipse stopped to work.

Starting app is completed with errors, but when i run debug, message could not set hardware breakpoint appear.

When i try to connect throught ISP, i see some program in CPUs RAM.
Adr 0x40000200

I dont know, how to remove this program, because it remains in CPU even if voltage is removed. I think its source of my problems. Could somebody help me?

Thank you

My Hardware:

OLIMEX arm-usb-ocd

I changed Jtag cable. Now everything seems to be OK.
