Transmit to court (e.g. send an email)
Arno should never happen, allocating exception blah blah blah certification blah blah
OlivierH not an issue blah blah ZCX-specific blah blah
Arno what about BE SJLJ? blah blah
OlivierH indeed blah blahArno in case of tasking blah blah
JeromeL Ah! No tasking involved in this case
Arno then not the issue here, case dismissed, and transferred to the certification court

So let's continue the investigation!

Second guess
Somee500v2instructionisnotproperlyexecutedbyQEmu?
Qemu istheculprit!!!!!!
![Page 25: AdaCore Paris Tech Day 2016: Jerome Lambourg - Cross and BareBoard Team Inside Out](https://reader031.fdocuments.us/reader031/viewer/2022030318/5a6e83307f8b9a70728b51fd/html5/thumbnails/25.jpg)

Third guess
MaybeVxWorks isnotproperlysettingthebitwhencallingasignalhandler?

OK, YOU CONVINCED ME:
I BOUGHT THE BOARD XYZ FROMVENDOR ABC.
I WANT TO RUN ADA.
HOW DO I DO THAT?

You’ll also need:
• Youwill need docs(such astheARMARM).• Andmoredocs(such astheMCUrefmanual)• Peopletohelpyou finding thedocsyou’remissing (such astheboard schematics)• Some updated docs• Internet&asearch engine (ifyou don’tknowone,letmegoogle that foryou…)
![Page 39: AdaCore Paris Tech Day 2016: Jerome Lambourg - Cross and BareBoard Team Inside Out](https://reader031.fdocuments.us/reader031/viewer/2022030318/5a6e83307f8b9a70728b51fd/html5/thumbnails/39.jpg)
Major steps to move forward
1. Power-uptheboard2. Connect toit3. Create anAdaruntime fortheboard4. Create anexample5. Load theexample into theboard
![Page 40: AdaCore Paris Tech Day 2016: Jerome Lambourg - Cross and BareBoard Team Inside Out](https://reader031.fdocuments.us/reader031/viewer/2022030318/5a6e83307f8b9a70728b51fd/html5/thumbnails/40.jpg)
I. Power up the board
Plugtheboard• See that it’s powered (at leastaLEDshould lightup)
• Ifnot, read thedoconhowtoplug andpoweruptheboard
![Page 41: AdaCore Paris Tech Day 2016: Jerome Lambourg - Cross and BareBoard Team Inside Out](https://reader031.fdocuments.us/reader031/viewer/2022030318/5a6e83307f8b9a70728b51fd/html5/thumbnails/41.jpg)
II. Connect to the board
e.g.find away tocommunicate with thetargeted board
![Page 42: AdaCore Paris Tech Day 2016: Jerome Lambourg - Cross and BareBoard Team Inside Out](https://reader031.fdocuments.us/reader031/viewer/2022030318/5a6e83307f8b9a70728b51fd/html5/thumbnails/42.jpg)
II. Connect to the board
Lookforaway toconnect toit• Lookat thedocthat comes with theboard• Youcan also search theinternet• Youmay ask Tristan*• OrFabien**• OrAnthony*** tocreate aGPSpluginforyou
* Maybe busy,orplaying fussball**Mayalso be busy,butdoes notplay fussball***plays fussball alot
![Page 43: AdaCore Paris Tech Day 2016: Jerome Lambourg - Cross and BareBoard Team Inside Out](https://reader031.fdocuments.us/reader031/viewer/2022030318/5a6e83307f8b9a70728b51fd/html5/thumbnails/43.jpg)
III. Create an Ada runtime
Well,here’s atough one• Ifwe already haveasimilar board supported,theruntime may only needminor adjustments:• Memorymapping (e.g.read thedoc),interrupts (c.f.doc),clock speed(RTFM)• Ifyou’re interested,gosee:blog.adacore.com/porting-the-ada-runtime-to-a-new-arm-board
• Else,you can [email protected] ;)
![Page 44: AdaCore Paris Tech Day 2016: Jerome Lambourg - Cross and BareBoard Team Inside Out](https://reader031.fdocuments.us/reader031/viewer/2022030318/5a6e83307f8b9a70728b51fd/html5/thumbnails/44.jpg)
At this point
• What you haveis:1. Aboard that is powered on(e.g.red led on)2. Some tool claiming itmay controltheboard3. Aruntime that you haven’t tried yet (e.g.aschrodinger runtime:it both works
anddoesn’t)

IV. So now is the time…
1. Turn aLEDON2. Wait abit3. Turn theLEDOFF4. Wait abit5. Goto1
…Forthefamousbaremetalhelloworld:“TheblinkingLED”
Scenariois very complex:
![Page 46: AdaCore Paris Tech Day 2016: Jerome Lambourg - Cross and BareBoard Team Inside Out](https://reader031.fdocuments.us/reader031/viewer/2022030318/5a6e83307f8b9a70728b51fd/html5/thumbnails/46.jpg)
IV. The LED example
This« simple »example implies many readings• MCUreferencemanual (ordatasheet):initialization ofthe« GPIO »,theGeneralPurpose I/Osystem.• Board schematics,tofind outonwhich pinoftheGPIOtheled isconnected to.
Thisone?
![Page 47: AdaCore Paris Tech Day 2016: Jerome Lambourg - Cross and BareBoard Team Inside Out](https://reader031.fdocuments.us/reader031/viewer/2022030318/5a6e83307f8b9a70728b51fd/html5/thumbnails/47.jpg)
V. Run all this on the board
Onceyou seem tohaveeverything setup:• Crossyour fingers• Load theexample onboard
Iiz bored.Pliz try again
– Either you endupwith what lookslike abrick
– Oryou can celebrate with ablinking LED(HEY!Comeonandlookatmy LED!Howfun!)
