- Is there a favored method for downloading files from the Critical Link Redmine site using a Linux console app? My software build server is a console only machine, and I'd like to be able to access CL Redmine files.
I have tried "wget ...

Thank you very much for your help. This uImage works.

I setup the toolchain and built the kernel for you. See attached. - BA 12:17 PM Software Development: RE: gcc 4.8 for OMAP-L138

Yes I am using the dbric3 hardware. Do you have a kernel image for it?

- The industrialio baseboard image expects the phy id to be 0:03. Your phy id appears to be 0:00. The kernel would need to be rebuilt with the correct phy id.

I think we're getting somewhere now. The newest kernel is working better. I went back to the original, unmodified Critical Link JFFS2 FS and the new uImage kernel, and I no longer get the ipv6 messages, and I the /dev/ttyS... - JC 09:30 AM Software Development: RE: gcc 4.8 for OMAP-L138

I tried booting the uImage Bob posted and it hung for me too. I've re-uploaded the uImage and this one appears to work. Sorry for the trouble.
You can find it on the Files tab or ...

- Ben, you shouldn't have to redo your filesystem. Just copy over the kernel.
- BA 03:33 PM Software Development: RE: gcc 4.8 for OMAP-L138

Thanks. Just to be clear, should I put the new uImage in /boot and re-create the jffs2 image? Currently the following is in /boot:
- uImage -> uImage-3.2.0+
- uImage-3.2.0+
My target is a custom board.

Ben, I apologize for the assumptions in my original advice. Any time you change a kernel you need to bring along the asociated modules (typically located in /lib/modules) for that kernel. You would've needed to grab the /lib/modules/...- BA 02:55 PM Software Development: RE: gcc 4.8 for OMAP-L138
- I did not build a new kernel. A kernel was already on my target system, and I believe it came from the MDK_2014-01-13.
The only thing I did was:

Did you build the kernel your currently booting from or was it copied from the old MDK_2014-01-13? - BA 02:44 PM Software Development: RE: gcc 4.8 for OMAP-L138

Thanks for the reply. I didn't build a new kernel based on the comment from Bob Duke, above:

The kernel your booting doesn't match the kernel modules its trying to load. Delete the kernel modules in /lib/modules/ and replace with modules from kernel you built. - BA 02:09 PM Software Development: RE: gcc 4.8 for OMAP-L138

I was able to load your ALPHA Linux file system onto my target, and I've had some success. The system is running, and I can establish an SSH terminal connection to it.

Part of the reason this filesystem is alpha is to discover differences from the old filesystem. We hadn't noticed this so good catch. Could you try creating the interface file and report back whether it worked? - BA 09:29 AM Software Development: RE: gcc 4.8 for OMAP-L138

- BD 10:38 AM Software Development: RE: MityDSP-L138F - Qt application not seeing USB keyboard
Mat,
You could try testing the Alpha MDK release we uploaded under the Files tab (2016.01). This is a Yocto-based MDK. It looks like Qt was built with keyboard support as part of this MDK.
- MJ 03:13 AM Software Development: RE: MityDSP-L138F - Qt application not seeing USB keyboard
- That's interesting, so it does look like the 12/03/2012 MDK (with Qt 4.7.4) was built with -qt-kbd-tty but not with: qt-kbd-qvfb and qt-kbd-linuxinput.
I noticed that it +does+ have the mouse support (-plugin-mouse-tslib -qt-mouse-pc -q...

Its been a while since I have worked in this area, so I'm a bit rusty... Are you launching your app with the -qws flag? This tells the Qt framework to start up the input server and might explain things...
cheers
