Re: a small roundup of graphics

Solved ! It seems arm-linux-gnueabihf-gcc behaves differently to gcc. It seems to need belts and braces ! I found I had to use "ldconfig" to add the path "/opt/vc/lib", something I should have done anyway. I also had to add the path to rpath-link and add the other library names. This is my new build...

Re: a small roundup of graphics - cross compile

I have compiled the 3186193 example from the git hub on my RPi without problems, and it works just great. Now I want to compile it using a cross compiler but this is giving me problems. I have succesfully setup a cross compiler toolchain as per this useful tutorial on a Kubuntu virtual m/c and hello...

Re: GNU C/C++ Cross Compiler + Eclipse Development Environme

Dear ZArie I have used the last part of the tutorial to start the debugger using "Manual" start of gdbserver. This seems to work. I had been using "Automatic" which I thought should cause eclipse to use ssh to start the gdbserver on the pi. I guess this must be broken. What I did notice about the se...

Re: GNU C/C++ Cross Compiler + Eclipse Development Environme

Dear ZArie The Cross option worked for me, this seems to the better soloution than all those path entries. I would be interested in how you get on with Ubuntu -> RPi eclipse debug setup. I have wasted quite an amount of time on it so far without much success. I have just tired bypassing eclipse for ...

Re: GNU C/C++ Cross Compiler + Eclipse Development Environme

The approch I have taken is to setup the simple "Hello World" project in a test workspace with all the paths configured etc. Then I have another workspace for development. To start a new project I use the "import" from the project explorer tab and copy in the "Hello World" project using the General/...

Re: GNU C/C++ Cross Compiler + Eclipse Development Environme

I have followed the tutorial ok and I am able to create a "HelloWorld" binary. Debug & Release. Both appear to work correctly if use scp to copy to the pi and execute them there. I have thus turned my efforts to trying to do a remote debug with Eclipse. What I want Eclipse to do when I launch debug ...

Re: USB/serial converters very broken on Pi

There is a lot of helpful stuff on the forum relevant to this but it isn't very easy to find.

Re: USB-Serial Convert hangs the Pi !!

Ok. I followed the procedure to install and run rpi-update. So I assume I have the latest and greaest version of Debian for my board. 1) I tried again with cat .profile >/dev/ttyUSB0. RPi crashed. 2) I tried a different model of FTDI USB-serial converter. RPi crashed with this also. 3) I tried a Pro...

Re: USB-Serial Convert hangs the Pi !!

So I looked at the trouble shooter. It mentions how to go about a "firmware" update. Did'nt notice anything about how update the Linux. So which is it I need to update. Is it the "firmware" in the chip or the Linux image on the SD Card ? Also I have done an FTDI search here and spent a long time rea...

<t>Hoorray !<br/> <br/> After connecting my Sony TV via HDMI I have figured the problem !<br/> <br/> It seems there were two issues.<br/> <br/> 1.  The RCA video output will not work if you have something plugged into the HDMI.<br/> <br/> 2.  I don't think the DVI-HDMI converter works even though it...

Re: No HDMI or RCA Video Output from brand new board.

Could it be my SD card ?  The big card I have is a SanDisk 16GB 45MB/s Class 10.  Having read here that class 4 is recommended ?  It think my card is faster than a class 4, but is that a problem ?
