I have tried flash magic on the other PC.but same thing repeats in auto baud.
I am not getting how the device is giving OK ,the part ID, terminal generated commands?
Also as i given you the feedback for the JTAG connectivity working OK.
Please suggest the way to program in ISP

Did you try changing your target hardware? How about the cable between the PC and hardware? If it is USB based then I would suspect that. Other than that I am out of ideas, sorry. :(

I am using the serial cable for ISP programmimg.
Is this issue related to device hardware ?
But 5 of the devices should not give the similar problem.

I've sent a description of the problem to NXP.

Hello,

for my project the date is soon reaching to release the prototype.
Please suggest :
shall i think for the change of the device? but it will be vary time consuming.as 5 boards are there already assembled with LPC2387 working with JTAG connectivity.
Is the LPC2387 is proved device at customers according to your forum feedbacks?

Changing the device may or may not help. It depends what is causing the problem. We aren't seeing this problem from other people so that makes me think it is something to do with your hardware design, serial cable or PC.

Another thought is to compare the schematics of the Keil MCB2300 with your board (www.keil.com/mcb2300). Look for differences. You might want to consider buying one of these boards to test with (www.lpctool.com).

Go to the page I gave you. Click on "Schematics" in the column on the left. Make sure you have Adobe Reader installed.

 :)I have checked with the schematic.
But i have not found the any dissimilarity.
 ::)except the pumping of pin P2.10
In the circuit it is automatic
& in my circuit it is manually i m doing it.
 :)Any way as there is no code programmed.After power on the control goes to boot loader only.
 :(Mean while i talked with NXP ,they have demanded me to send the hardware board.
can you send me the code for flash magic which will not go for auto baud?As in terminal i am getting the response for command ok @9600,19200.except the garbage for the synchronized

Getting Flash Magic to ignore an incorrect response from the device is not the solution. Something is wrong and you need to get to the bottom of it. If you ignore this then the problem may show up in other, unexpected ways. As I mentioned before we don't have reports of anyone else seeing this problem. If NXP have offered to look at your hardware then I suggest you send it to them.

Please post back with what you hear from NXP.
