1.2. Eclipse IDE Configuration for phyB!"D#$E%!#!&''(x

1.2.1. Host Setup

Toolchain: -or Compiling the Application we need the toolchain which you can easilydownload rom the 7elow lin8.

For Linux:

ftp:%%ftp.phytec.de%pub%+roducts%India%phy,-AD /E0A#A12234%5inu4%+D'6..%tools%toolchain%arm#corte4a#linu4#gnueabihf.tar.b7&

8et ip Address

" ifconfig eth '9&.'*.'.'& up

8et the gateway

route add default gw '9&.'*.'.'

For indo!s:

http:%%sourcery.mentor.com%public%gnu;toolchain%arm#none#linu4#gnueabi%arm#

&'&.9#*6#arm#none#linu4#gnueabi.e4e

1.2.2. Target Setup

For windows:#

ow you can see the Eclipse %or87ench as 7elow:

1.3.2 Creating a New Project

In this section we will learn how to create a new proect with Eclipse and how toconfigure the proect for use with the 0NB #


9/33

Enter the proect name myCello/orld and ?oolchain as


10/33

Set Toolchain Prefix & Path and Clic* Finish

8elect the


11/33

In 8ource file write myCello/orld.c and click on >inish.

K

1.3.4. Write simple Hello pplication

/rite a simple Cello Application in


12/33

?o compile your proect for the phyBOARD-WEGA-AM335x instead@ you will ha!eto use the 0NB #


13/33

Note First login manually using ssh as shown in snapshot below. Otherwise we will not be able to login in target because it reuires secure connection.

Note

If you are using windows so you have to use Winscp (or) directly copy thebinary into target board using pen-drive or sd-card.


14/33

Note

If you are using Window machine then you need the make utils using the

below link.

ftp:%%ftp.eMuation.com%make%2&%make.e4e

1.3. Changing the De,o !pplication

Now we will e4tend the myHelloWorld application. ?he e4tended myHelloWorldapplication will write an output to the first serial interface as well as to thestandard output.

-pen Eclipse if it is not opened yet

Double#click myCello/orld.c in the myCello/orld proect

>irst include the following two additional header files:

4include unistd.hJ4include fcntl.hJ

?hen add the function write;tty()@ which writes n bytes to the first serial

interface (which@ on the phyBOARD-WEGA-AM335x@ is connected to the systemconsole %de!%console):

5oid write6tty (char buffer@ int count)O

int outPout Q open (H%de!%consoleH@ ***)Pwrite(out@ buffer@ count)Pclose(out)P

R

Enter the following two lines in the main() function to declare the buffer andcall the write;tty() function.

char buf ST Q O H/elcome to the /orld of the phy,-AD /E0A#A12234U (serial)VnH RPwrite;tty(buf@ si7eof (buf) # ')P

In the screenshot ne4t page@ you can see the complete program.

15/33

8a!e your program after changing the code. 8elect +roect = ,uild proect from the menu bar.

The project will be build...

?he application will be compiled@ build@ copied to the target and e4ecuted.

1.4.1. Open Target "oar# using %inicom

-pen the terminal using minicom.

Enter user name as root and press Enter then type ls to see all the file.

ls

?ype .%myCello/orld to start the application

.%myCello/orld

Cello /orld

/elcome to the /orld of the phy,-AD /E0A#A12234U (serial)

close minicom.

In this section we had changed an e4isting application. /e also learned how toaccess the serial interface.

>irst@ we called the function open() on the de!ice %de!%console. ?he return !alue of this function was a file descriptor@ with the file descriptoryou called the function write() to send n bytes to the de!ice %de!%console.

After that@ the file descriptor was closed with the function close().

1.0. De9ugging an exa,ple proect

In this section@ we will learn how to use the 0NB debugger i.e.@ 0D, onthe host for remote debugging in conunction with the 0D, ser!er on thetarget.

>irst@ you will start the 0D, ser!er on the target. ?hen you will configurethe Eclipse platform and start the 0NB debugger out of Eclipse using theDebug !iew.

?he Debug !iew allows you to manage the debugging and running of aprogram in the workbench. Bsing the Debug !iew you will be able to setbreakpoints%watchpoints in the code and trace !ariables and registers.

?he 0D, client is running on the host and is used to control the 0D,ser!er on the target@ which in turn controls the application running on thetarget.

0D, client and 0D, ser!er can communicate o!er a ?


24/33

Fou ha!e started the 0D, ser!er on the target. ?he 0D, ser!er is now waitingfor connections on ?


25/33

8elect the Debugger tab


26/33


27/33

?he hostZs 0D, is now connected to the 0D, ser!er on the target.

/e ha!e configured our proect for emote#Debugging@ 0NB debugger inEclipse and connected the hostZs 0D, with the targetZs 0D, ser!er.

Now we can debug the proect.

1.).3. Setting a "rea/point

Now we will set a breakpoint in our program. ?his breakpoint will be set on thelast line of the function main(). If you resume the application@ the debugger willstop on this line.

28/33

8elect the last line in main(). ight#click into the small grey border on the left#hand side and select ?oggle ,reakpoint to set a new breakpoint

1.).4. Stepping an# Watc$ing 0aria-le Contents

In this part we will step through the e4ample proect with the debugger. we willalso learn how to check the content of a !ariable. E4pand buf in the ariableswindow


29/33

we will see the content of the buf !ariable in the ariables window.


30/33

/e will probably see a different address on the buffer pointer. ememberwhat address is shown in our caseP we will need this address later.

1.).!. Stepping an# Watc$ing 0aria-le Contents

In this section we will change the !alue of a !ariable. At the end of this part wewill see the effect of this change.

8elect the count !ariable in the ariables window

Double click on !alue and

1.).). sing t$e %emor' %onitor

In the last section of this chapter you will use the memory monitor tocontrol the content at a memory address.

8elect the 1emory tab


32/33

Fou will see follwing output on your screen.

Fou can see the contents of the !ariable buffer at the address ;x9ee9
