Failed to launch program edif2ngd

[NgdBuild 527] Failed to launch program edif2ngd: The pipe has been ended.

[NgdBuild 28] edif2ngd did not successfully complete.  Please check preceding errors for root cause.

 

This error sucked. Turns out you just need to re-launch the implementation run again. Didn't do anything special.

 

FPGA configuration encountered errors. Program FPGA failed

In this case the solution was actually simple. The console window was actually displaying something like this:

The following sections did not fit into Processor BRAM memory:
Section .jcr (0x88000944 - 0x88000947)
Section .eh_frame (0x88000940 - 0x88000943)
Section .data (0x88000830 - 0x8800093F)
Section .rodata (0x88000814 - 0x88000829)
Section .dtors (0x8800080C - 0x88000813)
Section .ctors (0x88000804 - 0x8800080B)
Section .fini (0x880007E8 - 0x88000803)
Section .init (0x880007B4 - 0x880007E7)
Section .text (0x88000000 - 0x880007B3)

Try using the linker script generation tools to generate an ELF that maps
correctly to your hardware design.

Which is a common error. Normally you can just make the BRAM larger in the EDK and regenerate. If it is still not working other things to try:

Booting from somewhere else:

Turning off ELF check if the ELF is too large:

Completely deleting Linker Script and regenerating:

"It looks like it's still trying to place the data and code into your BRAM.  Double check your linker script generation and manually delete the .ld file before rebuilding the workspace."

Failed to connect to Xilinx hw_server

Program FPGA failed

Reason:

   Failed to connect to Xilinx hw_server. Check if the hw_server is running and correct TCP port is used.

http://www.xilinx.com/support/answers/55431.htm

hw_server is used with the TCF infrastructure for debugging and it only supports Digilent and has to be launch manually from a shell.

The 'Auto Detect' option always chooses the TCF flow when the Digilent cable is plugged in.

If you do not want to use the TCF infrastructure, you must change the JTAG cable pull-down menu from Auto Detect to 'Digilent USB Cable' and resolve the error.

This change is found from SDK's Xilinx Tools -> Configure JTAG Settings. Again, changing from Auto Detect to Digilent USB Cable resolves the issue.

Editing Telemetry Packets for Vector File Testbench in Word

So I you have a packet that looks like this:

AA BB CC DD  11 22 33 44

And you need it to be in a vector read-in format for the simulator

AA
BB
CC
DD
11
22
33
44

You can actually use word find and replace. In this case replace any Two space with just one. And then replace all spaces with ^l

You can also find this setting under the "Special Characters" Button at the bottom of the Find and Replace Menu.

Also note you can use CTRL+SHIFT+8 to see the editing special characters

HDL:Compiler:104:104 - "path" Line XXX: Cannot find in library

So you typically get this error when importing an EDK created core into the ISE. You need to have the design include these libraries, to do this do:

1. Go to the  <Libraries> Tab
2. Type in the exact Library Name
3. in the Library Files location you actually need to go there, it will look something like /path/to/EDK/hw/XilinxProcessorIPLib/pcores/proc_common_v2_00_a/hdl/vhdl/
4. It should find all the files and you are good to go

 

Steam Error Code: -130 Failed to load web page / steam needs to be online to update

Hi all,

A friend of mine recently got a pretty terrible virus. After removing everything I discovered his steam also seemed to be broken. On the Steam "Ads" popup as well as the main page I would get the following errors:

Error Code: -130  Failed to load web page (unknown error). 

steam needs to be online to update. please confirm your network connection and try again

 

 

it turns out you can correct these simply by doing the following: 

 

Chrome Settings > Show Advanced Settings > Network > Change Proxy Settings > Lan Settings > Deselect ProxyCheckbox

 

I guess the viruses turned on some proxy...

Xilinx SDK Error Launching Program: Error while running ps7_init method

Sometimes I get this message:

Error Launching Program

Unexpected error while launching program Error while running ps7_init method:

Typically, this happens to me after I have copied a project in ISE over to my computer or overwritten some files.

The things you should check are:

• You have the system.bit bitstream selected
• When you go to Run as> Run Configurations> Xilinx C/C++ ELF go to the Device Initialization tab, and browse/refresh the .tcl even if it is correct
