To Build the W20xxA Application under Windows You need:

1. nios_3.2_win.zip from ftp://ftp.altera.com/outgoing/release/ and unzip it to some directory on your disk

2. Some old Version of Altera Quartus II from the same ftp server (I have made test's with 30sp1 Webedition and 41sp2 webedition)

3. A complete Build directory from Hayo (for example BlueFlash_Build_0_62.zip from the google group)

How to Install:
 
1. Install Quartus II (you don't need to do the registration for a license key!)
2. Install nios 3.2 (run setup.exe)
3. Add PATH entry's (System property --> Advanced --> Environment Variables)for:

	<Quantus Installation path>\bin\cygwin\bin  (for example C:\altera\quartus41sp2\bin\cygwin\bin)

	<nios 3.2 Installation path>\bin\nios-gnupro\bin (for example C:\altera\kits\nios\bin\nios-gnupro\bin)

Attention:
	If You already have Cygwin installed on Your system take care that the nios gcc used the right cygwin installation! 
	(unfortunately newer cygwin build's are not compatible with the nios gcc tools)


4. Edit the Makefile inside Build directory:
	change line
		sopc_kit_nios = /opt/cdk4nios
	to
		sopc_kit_nios = C:/altera/kits/nios/bin/nios-gnupro (Or wherever You installed the nios 3.2, attention use '/' not '\'!)

Now you should be able to run make from the command prompt (go to the directory where the file Makefile is).

You should see something like this:
