Hi All
Where i can find information about:

  1. using JTag to set the breakpoint in memory and trap the cpu, then single-step running in assembly level?
  2. what jtag i can use to work with this board and where i can buy it?
    thanks

The programming method listed here uses JTAG to program the device:

The segger JLink is also supported:

Either should allow for the use of GDB for debugging.

There is freedom studio that provides a eclipse based graphical IDE if you are interested.

I have never tried but let me know if you need help setting it up.
