led

Stupid blinking leds, just to verify toolchain.

Building on linux

xilinx ise env must be sourced and makefile is in build directory.

Example:

. /home/opt/Xilinx/14.5/ISE_DS/settings64.sh
cd build
make

Load to board

I use a raspberry pi for that task with urjtag

rp gpios must be connected to omdazz fitting to the cable options ( numbers are gpio nubmbers not pin numbers)

Initializing GPIO JTAG Chain
jtag> detect
IR length: 6
Chain length: 1
Device Id: 01000100000000000010000010010011 (0x44002093) 
  Manufacturer: Xilinx (0x093)
  Part(0):      xc6slx16 (0x4002)
  Unknown stepping! (0100) (/usr/local/share/urjtag/xilinx/xc6slx16/STEPPINGS)

This can be fixed by

adding 0100 xc6slx16 4 into /usr/local/share/urjtag/xilinx/xc6slx16/STEPPINGS

( Is unknowen if this is the correct way to fix this - thats why not commited into urjtag)
