I am getting the following message while loading my code to the LPC2148
using JTAG.

Warning: Target inconsistency detected in Memory range 0x00000000-
0x0000003F

Any idea of why this might happen.

I am using the Wiggler JTAG. Debugging using the IAR with HJTAG server.

This is the warning message I recieve when I start debgging. The LPC2148 seems to be locked in some mode.

The code I was able to execute earlier is no longer working. I have recycled power to the board.
The HJTAG recognizes the chip and the board powers-up but it appears that I am not able to reset the board using HJTAG.

Thanks and Regards,
Sumit.

Is there a way of resolving the checksum error if the LPC2148 is locked with it??

I'm not familiar with the message, and I don't know what board your
LPC2148 is soldered on. You probably have the on-chip ISP boot loader
available. If so, boot the chip into the ISP, and reconnect. If IAR
offers a simulated reset vector catch, you could set that up before you
connect. Alternatively, set a break to stop execution at a known safe
location in your code. If you don't know, start at the reset vector.
Proceed from there to see if your application is doing something
untoward.

Steve, Thanks for your inital suggestion. I ended up erasing the flash and loading the code to flash. Now it appears the USB mouse demo code seems to be working fine.

I am using the Olimex Header board for LPC2148 and wiggler jtag for programming it with the IAR and HJTAG.

However, the code for the UART still seems to have issues. Could I have bricked specific pins on the chip. Is there a way of checking this.
I mean, I can write code to find out if the IO is working and checking with simple LEDs but even with the IO working could it be possible that I brick the UART function only(I am pretty sure that my code ran fine from the RAM earlier).

Best Regards
