[Lancelot] Help with Lancelot reference example

[Marco]

Hello Jowen,

For some reason I forgot to include the flash.flash file in the ZIP-archive.
Thanks for the notice. I updated the website and included the file with this
e-mail. Copy this file in the lancelot/software/lancelot/debug directory.
This should solve you first issue.  

The dummy file error is reported when Quartus II v4.1 is used in combination
with Nios II 1.1 or Quartus II v4.2 with Nios II 1.0. You should use Quartus
II v4.2 and Nios II 1.1. 

It could be that your flash is corrupted and therefore the reference not
working properly. Try to erase the whole flash device and then restart the
lancelot_flash_image utility. Use this command line to erase the flash
device;
Nios2-flash-programmer --base=0x800000 --erase --sof=<Nios II install
directory>/bin/components/altera_nios_dev_board_cyclone_1c20/system/altera_n
ios_dev_board_cyclone_1c20.sof   


Best Regards,

Marco

Hello,

I am using the Lancelot VGA card with an Altera Cyclone EP1C20 for a school
project.  Right now, I can't even get the Lancelot reference design that is
on the www.fpga.nl website to work.  Here's what I've done:

- followed the instructions in the manual under "5. Reference Designs".
This produced the following error:

Mar 12, 2005 9:01:04 PM - (SEVERE) nios2-flash-programmer:
com.altera.memory.RWM
emoryException: File not found: ../software/lancelot/debug/flash.flash
Mar 12, 2005 9:01:04 PM - (SEVERE) nios2-flash-programmer: Unable to read
input- data from: ../software/lancelot/debug/flash.flash, exiting


So I...

- program the Cyclone with Lancelot_Cyclone_EP1C20.sof using Quartus, this
performs successfully
- open NIOS II IDE, created a new C/C++ application from the
./software/lancelot location, set the SOPC Builder System as .\nios.ptf, and
CPU as cpu, and included the lancelot_syslib folder as the system library
- I build the project and get the following error: "***
[C:/ece496/lancelot/nios_sim/dummy_file] Error 2"
- I create a empty file called dummy_file in C:/ece496/lancelot/nios_sim and
build again, and it works now
- Select Run.. from the Run menu, click the Run button, and everything seems
to work right since I see the following on the console window:


nios2-terminal: Warning: The JTAG cable you are using is not supported for
Nios
nios2-terminal: II systems.  You may experience intermittent JTAG
communication
nios2-terminal: failures with this cable.  Please use a USB Blaster revision
B
nios2-terminal: cable or another supported cable.  Please refer to the file
nios2-terminal: errata.txt included in the Nios II development kit documents
nios2-terminal: directory for more information.

nios2-terminal: connected to hardware target using JTAG UART on cable
nios2-terminal: "ByteBlasterII [LPT1]", device 1, instance 0
nios2-terminal: starting in terminal mode only (Control-C exits)

followed by:

Welcome to Lancelot!
====================
Switching image
Switching image
Switching image
Switching image

It keeps outputting Switching image, but my monitor doesn't display
anything, and the status LED keeps going green-orange-green-orange...

After having built the project, the flash.flash file is created, so I try
following the instructions in the user manual again.  It outputs this:

Lancelot Image Loader
===================
This utility loads the flash of
the Altera Cyclone / Stratix Nios Development Board with the Lancelot PLD
configuration, Nios software and images.

and I press the reset config button on the Cyclone board, but nothing except
the blinking LED.

Any help would be greatly appreciated, and yes, the monitor is working.  The
Lancelot is plugged into the J11, J12, J13 pins.  The problem isn't the
parallel cable I'm using with the Cyclone board is it?

Thanks,
Jowen
