hi all.

If I am using lpc2000 flash utility device geting detected and massage shown
below.
*"C:\Program Files\Philips Semiconductors\Philips Flash
Utility\LPC210x_ISP.exe" "D:\Keil\ARM\Examples\Blinky\Obj\Blinky.HEX" 12000
LPC2124 COM1: 9600 1
*
But while using the Flash magic software, the MCB2140 is getting connected @
9600 baud rate but not getting programmed. The following message is
displayed.

*"Failed to read the device signature (operation Failed. (reading
signature)). Accessing a device using the wrong protocol could render the
device unusable. Do you want to continue? Y/N
*
The same if I tried with keil using Flash Magic it is getting connected and
does all the initializations but while erasing the device it is showing the
error. Following is the message displayed.

*"C:\Program Files\Flash Magic\FM.EXE"
DEVICE(LPC2124,12.0)ERASE(DEVICE,PROTECTISP)

Hi Sandip,

I would like to know what you get when you run SILL as "SILL COM1".
You can fetch sill from the link in my page:

http://www.cse.unsw.edu.au/~jayas/esdk/sill.html

and make sure that you do not install any jumpers that connect RST or
BLD to DTR or RTS on the serial port. You just run SILL, then
manually reset the board with BLD jumper installed (not to RTS, but to
GND) or BSD button held down.

If it works, then you can try the try "SILL -i COM1" to see if you can
load SILL to on-chip flash and run it as per the documentation.
