>>How to repair an Excalibur Development Board?

Hi Kerri,

I think mine was nios dev board because I don't think there was any of a device called or marked ARM® (I think I'm just very very stupid), I only know there was a FPGA has "ALTERA® APEX™ EP20K200EFC484-2X" printed on, and has "EXCALIBUR™ NIOS™ ALTERA®" printed on the back. Then I just followed your instructions, the result is:

device 1) SEEMs okey, but the temp. of the fpga was not right, and couldn't pass the timer test (the basic debug program), others seems right.

after the board's power on and shows me the "ready" signal:

$ nr -t#  2004.10.01 23:17:40 (*) nios-run.pl warning: .../lib/Makefile not found#  2004.10.01 23:17:40 (*) defaulting to serial (-r)
nios-run: Entering terminal mode over COM1: at 115200 bps
nios-run: Terminal mode (Control-C exits)
-----------------------------------------

then I press reset:

(Return address is 0x00000000

Welcome to the Nios development board

 MAIN MENU
     a:  Timer
     b:  UART
     c:  Buttons & Switches
     d:  LED
     e:  Seven Segment Display
     f:  Bus & Memory
     q:  Exit
----------------------------------
Select Choice (a-g):

but as I know, it's abnormal, it should show me the second if I have the board pluged and ready.

Abnormal on timer section.

device 2) quite a simple result, doesn't work, the temp. grows drastically and only shows me "waiting for target......" there was no time for its waiting before the fire, and just I could do was unpluged it.

any more tips? or it just dead?

really thx.
