Booting from EPC4

When I try to program an EPCS device using the Nios II Flash Programmer and my own custom Cyclone board, I get the error: make: *** [epcs_controller_boot_rom_programflash] Error 5

or in more detail.....

make: Entering directory `/cygdrive/f/projects/emshw/full_featured/software/ems_boot/Release'

In order to program flash, you must first create a purpose-built

flash-programming design (i.e. FPGA configuration) and associate it with

your particular board. The Nios development kit is delivered with purpose-built

flash-programming designs pre-built for several development boards. If you wish

to program flash on your own board, you must first create a flash-programming

design.

The process of creating a flash-programming design for your board is mostly

automated. From a bash-shell, execute this script:

mk_target_board --help

The help-message includes references to other documentation on programming

flash and targeting Nios systems to custom board designs.

Then this windows message-box pops up....

java.exe - Application Error

The instruction at "0x032c2140" referenced memory at "0x033e2390". The memory could not be "read".

Click on OK to terminate the program

Then I click OK and the Console output continues with...

- exiting.
