     1Debugging PicoBlaze systems can be tricky.  Xilinx provides a JTAG loader which has exactly one function:  overwrite the entire program code with new code and reset the PicoBlaze.  Also, only an executable with no source code is provided.  This page describes an alternative whereby the PicoBlaze is given read/write access to it's own program memory, thus allowing for a small boot loader to accept new hex code for all or part of the program memory.

     3In addition, "in memory" code editing and debugging is made possible.
