Hello folks,

I have just got an AT91SAM9263EK board and I tried some sample programs on it. When I am loading the bin files directly to the board without
debugging they are working fine.

But when I am trying to compile the source using Eclipse IDE and debug it using the segger debugger it is giving following error

J-Link ARM V3.74f Error

Bad JTAG communication: Write to IR: Expected 0x1, got 0x0(TAP Command : 15) @ off 0x1979.

The GDB server log is like this
