Jtag debugging issue with my custom build circuit

[rajeshjat56]

I am not able to debug my lpc 2292 board, i think i am having some hardware issue, signals are as per schematic image.

I have attached my JTAG connector and controller connection.

Rtclk is pull down with 4.7k resistor and boot loader is also pull down for programing.

Please help me,it is not debugging but programing from JTAG.

I have done circuit as debug circuit design consideration mention in above link, but still i am not able to debug and after debugging option selection, it goes into directly to exception vectors, infinite loop and code run,but not single step debug.

Hi, Rajesh,

As you said " it goes into directly to exception vectors, infinite loop and code run,but not single step debug.", it seems that you have downloaded the code to flash, the JTAG circuit is fine, but the code has issue so that it can not run. Pls try to check your code.
