Hello all
I am using LPC2148 and I am facing a little problem when programming it using Keil Compiler. The problem is, Keil gives the following error when I download the code to the procesor.
Info: Could not measure total IR len. TDO is constant high.
To overcome this I am running J-Link Commander to identify the code and the response is...
SEGGER J-Link Commander V4.68 ('?' for help)
Compiled Apr 6 2013 00:11:06
DLL version V4.68, compiled Apr 6 2013 00:10:46
Firmware: J-Link ARM V8 compiled Nov 14 2012 22:34:52
Hardware: V8.00
S/N: xxxxxxxxxxxxxx
Feature(s): RDI,FlashDL,FlashBP,JFlash,GDBFULL
VTarget = 3.287V
Info: Could not measure total IR len. TDO is constant high.

No devices found on JTAG chain. Trying to find device on SWD.
No device found on SWD.
Did not find any core.
Failed to identify target. Trying again with slow (4 kHz) speed.
Info: TotalIRLen = 4, IRPrint = 0x01
Found 1 JTAG device, Total IRLen = 4:
#0 Id: 0x4F1F0F0F, IRLen: 04, IRPrint: 0x1, ARM7TDMI-S Core
Found ARM with core Id 0x4F1F0F0F (ARM7)
ETM V1.2: 1 pairs addr.comp, 0 data comp, 4 MM decs, 1 counters

After running J-Link Commander when I load the program using Keil.... It works. Later, if I switch Off the board and turn it on and then try to program it again. It gives me the same error. I have to run, J-Link commander again to program it. I have attached the circuit, please let me know the mistake that I am making here please.
