Cyclone EP1C20 Dev Board

 Programming:

  Jtag 9.0

   Since the nodes are not detected, no programs are able to be uploaded, and hence zero functionality. The example below shows output from jtag 9.0, note that the -n switch should show all running nodes.

 [tom@garak full_featured]$ jtagconfig -n                                                       
1) USB-Blaster [USB 3-1.1]                                                                     
  020840DD                                                                                    

 To get around the limitation, find a jtag_client.so file from quartus 7.2, located in /usr/altera/quartus7.2/linux/libjtag_client.so (note this is my install dir, which may differ).

• rename your original jtag_client.so to jtag_client.so_orig just in case
• overwrite file from ver Q9.0 with the Q7.2 one
• restart jtagd as root if required

Note: the quartus7.2/linux directory contains the jtag_client.so  for the 32-bit version.  Most Quartus installations come with both 32 and 64 bit versions.  If you are running 64 bit, you are well to copy both 32 and 64 versions respectively, but don't mix them up!  

• quartus/linux/jtag_client.so  32-bit
• quartus/linux64/jtag_client.so  64-bit

After doing so, the output should finally list the running nodes:

 [tom@garak full_featured]$ /software/altera/quartus/bin/jtagconfig -n
1) USB-Blaster [USB 3-1.2]
  020840DD   EP1C20
    Node 11104600
    Node 0C006E00

 This concludes the programming howto.

Examples from Quartus 7.2

Since the nios2eds 9.0 no longer contains any example designs for any pre Cyclone II boards, the designs have to be borrowed from ver 7.2. Perhaps I will post the files here.

In the dir /software/altera/nios2eds/examples/verilog/niosII_cyclone_1c20/full_featured

you will find the whole project.  No changes are necessary to compile with Q9.0

Some warnings about deprecated directives should be ignored.
