[Buildroot] Qt on AM3517EVM

[Charles Krinke]

First of all, +100 for Thomas, Arnout and Julian. This morning, I was
able to load the jffs2 compiled file system from buildroot and run
"ts_calibrate" and got a functioning touch screen and color LCD with
Qt on the LogicPD AM3517EVM after *removing* the environment variable
QMAKESPEC which the TI-SDK insisted on adding to my .bashrc.

Of course, no sooner had I gotten it to work then my customer says
"Thats cool, how about Qt5?"

So, ... are we considering either a Qt5 bump or either Qt4/Qt5 with an
xconfig option?

This proves, *again*, that no good deed ever goes unpunished.

Great.

I think Qt5 needs a separate package from qt4, because many, many
things have changed in Qt5. Also Qt5 apparently requires an OpenGL
renderer, which wasn't the case in Qt4, so we will probably be keeping
Qt4 around for quite a while for low-end platforms.

Anyone willing to work on packaging Qt5 is definitely more than welcome
to contribute such effort.

Thanks!

Dear Thomas:

Could you give us (me) a few pointers on the pre-requisite packages
and the path to move along to get Qt5 put together for buildroot?
Maybe with your guidance one of us can get at least partway down that
path.

Hi Charles:

Glad to hear that you succeeded in building!

Since you're targeting a TI-chip, have a look at these links:
http://gpupowered.org/node/8
https://github.com/prabindh/qt-configs

For a Qt5 package, I'd wait a bit longer until it reaches final, current
release plan:

Beta : release expected by mid-July 2012
Final: release expected by September 2012

Thanks for the encouragement, Julian. I agree on the Qt5 question,
especially as I have a long list of things that need to be done first.

One thing I have been struggling with the the last day or so is the
console. Maybe you have a suggestion.

TI defines their 3rd serial port as the console and their uImage sets
it as "ttyO2" (that's ohh, not zero). Their uImage displays this as it
starts. I can also see that TI's omap-serial.c driver enumerates as a
console. I can also see that if I poke the THR (transmit holding
register) directly on their 3rd uart, I can emit a character.

But, what doesnt work is respawning the console as ttyO2 in inittab or
$ echo "astring" > /dev/ttyO2

So, something else is not quite right. I can boot to linux as long as
I use single user mode.

Any suggestions or comments (including RTFM, although a URL would
help) would be appreciated.

Charles

[Buildroot] Qt on AM3517EVM

[Yegor Yefremov]

Hello Charles,

I have an am3517 based board and have no problems with ttyO2 and BR. I have just configured ttyO2 in the system configuration, so that inittab has it there and I can login. Afterwards I can specify a password and the next time I login I also get a password prompt.

What kernel are you using?

Best regards,
Yegor

  You're not, by any chance, using a static /dev ?  ttyO2 is not in
target/generic/device_table_dev.txt I'm afraid...
