I am trying to compile the samples from gnsdk on a Raspberry Pi (model B, I guess). But I get an "illegal instruction" when I run the sample.
Can I do something clever?
Thanks in advance.

Did you compile that sample source code by using cross compile?

I would like to implement Device DMFT based on this Microsoft article.
Did anyone has any experience with it and could share code sample?
I did find some “Driver MFT” code samples on the Microsoft website but none for “Device MFT”.
Here's the sample code from MSFT.
You can compile and register using the dll file generated.
I've been successfully using Vivado and the SDK to develop VHDL and C for the Zynq XC7Z010 on a Digilent Zybo board. I've also been using the GNAT GPS IDE to learn Ada targeted to an STM32F4 processor (using one of the supported development boards).
GPS also ships with a set of zynq7000 run-times targeted to the XC7Z020 (as far as I can tell). Having looked through the BSPs for these target I believe that the code generated should also run on the XC7Z010 as the ARM cores appear to be the same. It may turn out that there are differences, in which case I will have a go at building a specific run-time based on the existing zynq7000 BSP (Adacore have documented this process and give an example for generating a new STM32F4 BSP).
My main problem is I'm not sure how to load and run the generated Ada elf file on my Zybo. I have tried to generate a BOOT.ini file containing a FSBL (built with the SDK and using my exported hardware from Vivado), a bit-stream and the Ada elf file (The the Zybo has an MicroSD interface that can be configured as a boot device, this works perfectly with a bit-stream and C elf produced via Vivado / SDK).
Anyway, this didn't work... I'm guessing that it might be a linking issue, or a boot loader issue, or similar. With my current level of knowledge I'm just not sure at this stage.
Any advice or pointers would be greatly appreciated!
It turns out that my BOOT.ini was fine, the problem was related to accessing custom AXI registers defined in my bit-stream. If I remove these references from the Ada the generated ELF file works perfectly. For example, printing over the Zybo's VCP using Text_IO.Put_Line(), using Ada run-time delay and Clock operations etc.
For some reason the AXI interface isn't working when I boot an Ada ELF file. If I substitute this for the equivalent C, then all is well.
This particular problem is currently unresolved, but not related to my original question!
(It might be that the Ada run-time is relying on the FSBL or u-Boot to have initialised this, not sure. Feel free to comment if you know, I'll also add a comment when I resolve this)
**** Update ****
Here is some additional background and a description of what I had to do to get my custom AXI IPs to work.
The provided AdaCore BSP (Board Support Package used to build the run-time) is targeted at the Xilinx XC702 development board. I'm using a Digilent Zybo (the older version). The two boards use different Zynq parts, the XC702 is based on a XC7Z020 and the Zybo uses a XC7Z010 (there is a new version with a XC7Z020 option).
I followed the AdaCore instructions (available on their web site) and built a BSP specifically for the Zybo. Initially I just updated the clock details as the Zybo runs at a different speed and then verified that the Ada delay function worked correctly (provided as part of the Ravenscar run-time built from the updated BSP). However, my custom AXI IPs still didn't work...
To cut a long story short, the Ada run-time contains as assembly file called start-ram.S that amongst other things sets up the MMU. There is an include file called memmap.inc that contains the actual MMU page definitions as a series of .long directives. I had to update the AXI_GP0 address entry by editing the particular directive to,
.long 0x43c10c16 # for 0x43c00000, axi_gp0
Previously it was set to 0x00000000 # for 0x43c00000, *none*. These entries are decoded within start-ram.S and then used to configure the MMU (the top 12 bits set the page and the remaining bits are chopped up and used as page config).
So, once I edited this file in my Zybo BSP and re-built the run-time, the IPs became accessible from the PS and worked as expected. This all took a while to figure out, but was worth it as I learn loads whilst exploring the dead ends!
I hope this helps someone in the future, I also highly recommend Ada for Zynq development especially if you ultimately need DO-178 certification, or similar.
I am new in xcode.
I got recurring message error when building for testing:
*PWRequest.m
User defined issues
"ARC is required to compile Pushwoosh SDK"*
In code it shows:
#if ! __has_feature(objc_arc)
#error "ARC is required to compile Pushwoosh SDK"
#endif
I don't understand. I added a new pushwoosh sdk.
I thank you very much for your help.
You can set ARC on a file basis. Go to the BuildPhases->CompileSources. You can select sources there and pass ARC flag.
Same as here:
How can I disable ARC for a single file in a project?
but with -fobjc-arc flag
You can use XCode project that comes with the SDK. In this case you'll be linking to the output (library) that is produced by this project.
Hope it helps!
So if you want to use Pushwoosh in your app, you're going to need to turn on ARC in your project settings.
And then you'll be using ARC in your app.
Which is somewhat nicer than doing good old fashioned Manual Retain / Release memory management, yes?
If you are determined to use MRC (manual retain count), then follow the steps in this related question.
I have created a new build definition for TFS 2010. After building my C# solution I would like it to execute a couple of unit tests. These unit tests require an XML input file, so I have a [DeploymentItem] attribute to the test methods which provides the relative path the XML files. If I run the unit tests from within Visual Studio they pass ok.
When the unit tests get run following a build (via my build definition), they fail with: "Microsoft.BizTalk.TestTools.BizTalkTestAssertFailException: Input file does not exist..."
It would be great if I could get to a trace of what the build agent was trying to do, to help with troubleshooting.
Does anyone know how to get such a trace output? I guess I could increase the verbosity of the trace output from the main solution under test but I don't think that would give me any indication of where the build agent was looking for the test input XML or why?
Thanks

I found it! Needed to click the "View Log" link from the screen that's displayed following the build. I had been looking at the default view of "View Summary"
I'm trying the sample demo of selenium flex API. After following the instructions on the main page for compiling the project with sfpi.swc and taking the generated selben.swf in bin directory and trying to run some test(assertFlexText) using Selenium IDE, I get the following error:
[error] Function getFlexText not found on the External Interface for
the flash object selben
I have tried several other flex tests and got error messages similar to the one mentioned above.
For some reason I believe that the generated selben.swf through the automatic build of project in flex builder is not the desired one, though it didn't indicate any build problem after including sfpi.swc.
Any idea?
I use SeleniumFlex Api and SeleniumIde for my projecy with excellent result BUT using my own version of each of one. Your error maybe is for not include the lib of SeleniumFlexApi in the compile time( -include-libraries "libs\SeleniumFlexAPI.swc" ).
After that u can enable capture and replay with SeleniumIde change the main source (read this post) and use the user-extensions.js (in the SeleniumFlexApi project) with the SeleniumIde user option. Its really easy.
With these change u can capture and replay in firefox (v 3.06 or minor) and after that, if u use java, u can use Flex-UI-Selenium, Flash-Selenium for ur integration test with SeleniumRC.
I hope this information be usefull. I u have any question let me know.
