JC 09:34 AM Software Development: RE: gcc 4.8 for OMAP-L138: Ben,
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? Jonathan Cormier
BA 09:29 AM Software Development: RE: gcc 4.8 for OMAP-L138: I want to set a static IP address on my target using the ALPHA Release 2016.01 file system, but I was surprised to see the /etc/network/interfaces file didn't exist in the file system image. I expected to see this file populated with so... Ben Atkinson

MJ 03:16 AM Software Development: RE: MityDSP-L138F - Qt application not seeing USB keyboard: Hi
Thanks, I did very quickly look at the 2015 Alpha release but didn't see the Qt libraries.
At the same time I was investigating the Qt 'configure' parameters posted above and what is suggested by https://wiki.qt.io/Building_Qt_for_E... Mathew Jones

JC 11:23 AM Software Development: RE: gcc 4.8 for OMAP-L138: Here is the command we run to create the jffs file for the original MDK. Where $root is the path to the extracted filesystem. Jonathan Cormier
BA 11:01 AM Software Development: RE: gcc 4.8 for OMAP-L138: We have a tool that reprograms the root FS on our target device with a jffs2 file. I saw in the Release 2010.05 there are root FS files in both the jffs2 file and a tar.gz file. Do you have a tool or procedure that can convert the mity... Ben Atkinson
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.
Bob Duke
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... Mathew Jones

JC 03:19 PM Software Development: RE: MityDSP-L138F - Qt application not seeing USB keyboard: The build logs for the 4.7.4 qt show the following configure. According to this neither qt-kbd-linuxinput nor qt-kbd-linuxinput were built but qt-kbd-linuxinput was. Jonathan Cormier
MJ 10:56 AM Software Development: RE: MityDSP-L138F - Qt application not seeing USB keyboard: Hi Jonathan, thanks, I've read something similar or the same links.
I've just tried Mathew Jones
JC 09:13 AM Software Development: RE: MityDSP-L138F - Qt application not seeing USB keyboard: http://doc.qt.io/qt-4.8/qt-embedded-charinput.html#specifying-a-keyboard-driver
The above link lists the TTY and LinuxInput driver as what would be needed for keyboard input.

MJ 08:17 AM Software Development: RE: MityDSP-L138F - Qt application not seeing USB keyboard: Hi Tim
I am currently launching my application with the -qws flag, e.g. Mathew Jones
TI 07:14 AM Software Development: RE: MityDSP-L138F - Qt application not seeing USB keyboard: Mat,
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

MJ 04:42 AM Software Development: MityDSP-L138F - Qt application not seeing USB keyboard: Hi
I'm having trouble with Qt getting input from a USB keyboard. USB mouse input is fine.
I have a MityDSP-L138 running on the IndustrialIO dev board, connected to a monitor via DVI.
The USB keyboard happily works with the console o... Mathew Jones

MJ 08:52 AM FPGA Development: RE: Linux application cannot read/write FPGA registers: Hi Greg
Excellent, that has definitely helped as I can now see /dev/0 after the following two commands (with FPGA loaded from uBoot). Mathew Jones

MW 12:43 PM Software Development: RE: DVI Framebuffer (fpga i2c) problem: Hi Mathew,
Very sorry about that. I didn't catch the LX45 version. The LX45 has some pins that are not bonded to the FPGA package causing the limitation on our devkit (originally designed for the LX16).
Are you using a widescree... Michael Williamson
MJ 11:26 AM Software Development: RE: DVI Framebuffer (fpga i2c) problem: From our investigation and suggestions from other wiki/forum pages it is apparent now that it is not possible to output to a DVI monitor from a MityDSP-L138 + Industrial IO development board, with the LX45 FPGA. We have since purchased t... Mathew Jones
GG 11:35 AM FPGA Development: RE: Linux application cannot read/write FPGA registers: Hi Matthew,
First we need to deal with the issue of /dev/0 not being present. Using /dev/mem is ultimately not what you want to do as you will run into caching issues.
/dev/0 is created after the FPGA is loaded and the device driv... Gregory Gluszek
MJ 11:16 AM FPGA Development: Linux application cannot read/write FPGA registers: I am trying write a simple C application (for Linux on the MityDSP-L138 ARM) that can access registers within an LX16 FPGA image, which is yet to be implemented but I'd like to get the basics working for now with any of the CriticalLink ... Mathew Jones

BD 05:40 PM Software Development: RE: gcc 4.8 for OMAP-L138: Also, please make sure you perform the extraction as the root user: Bob Duke
JC 03:51 PM Software Development: RE: gcc 4.8 for OMAP-L138: Yes, extract the tar ball onto the root filesystem, but make sure to erase the existing one first. And backup your important files of course.
Please let us know if there are any tools missing from the new filesystem that you used in ... Jonathan Cormier
BA 03:23 PM Software Development: RE: gcc 4.8 for OMAP-L138: Bob,
Thank you for the response regarding the new gcc cross-compiler for the MityDSP-L138. Now that we're back from the holidays, I was able to successfully cross compile our application on my build machine.
I'm a little unclear, ... Ben Atkinson
