The step by step instruction based on the SOPC builder
is outdated. But you can still find it in the archive. If you are searching a step
by step instruction using the Qsys system, take a look at the
Based on the Qsys system I will provide you here the FPGA design files for the Altera DE1
and DE0-nano board for the ChibiOS project.
For this tutorial an Altera DE1 Board was used:
The DE1 board provides a lot of functionality. But for this tutorial only the following
subset was used:
- Cyclone II (EP2C20F484C7)
- Build in USB Blaster
- 8MByte SDRAM
- 4 Push-button switches
- 10 Toggle switches
- 8 Green User LEDs
- 10 Red User LEDs
- 50 MHz oscillator
Quartus and Cyclone II
Some notes for the correct Quartus version.
I tried the latest version, which was 13.1 in the moment. Unfortunately the Cyclone II
support was removed here. Ok, quick check at the Altera page. The latest version where
the Cyclone II will be supported is 13.0sp1.
But with version 13.0sp1 I had a problem to create the Board Support Package within Eclipse.
It looks that other users have the same problem too. Unfortunately the workaround could not solve my problem how I
create the BSP for ChibiOS. The next version I have tested was 12.1sp1
I will make it short, with 12.1sp1 I had problems to create new components under Qsys.
And it looks that other users have problems too. Again, one step back, next test was made with 11.1sp2.
This was the version I still used under Windows XP before.
Btw, here I am using Windows 7 64-bit. With 11.1.sp2 I had no problems with the
Component Editor. But the USB-Blaster could not be found. A solution could be found in the
Altera Knowledge Base.
Now I could program the design with Quartus II and I want to start the software development
with the Nios II SBT. Short hint, Eclipse must be started as administrator.
See Altera Wiki.
After some tests it looks that the debugging was not stable here. Sometimes I could debug
the project, sometimes it was not possible to download the project into the Nios II. It takes
a while to found the problem, the USB-Blaster driver. I could solve the problem by using a new
driver from the Altera Knowledge Base here.
For the moment it looks that I have found a stable solution which is working for the Altera DE1 Board.
