- Hmm no noticeable errors. You can double check the kernel, on the booted device for the spidev support:
- FF 04:21 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: Spidev issues
- I added the boot log for the ECC errors also.
- FF 03:39 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: Spidev issues
- Hope this helps.
- JC 03:15 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: Spidev issues
- Can you attach the bootlog for the device?
- FF 03:09 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: Spidev issues
- It looks like it is enabled to me.
- JC 01:41 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: Spidev issues
- A pinmux conflict would likely cause the device not to work but it would not affect the creation of the spidev device file.
You need to make sure that SPIDEV is enabled in the kernel. It doesn't look like it is by default. - The dev kit baseboard file has been modified to include a "spidev" device, and the kernel was compiled to include the SPI device driver for users. However, the expected /dev/spidev0.1 file is not generated. Can a pinmux conflict with o...

- 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...

- After the links were corrected on my system, it works using iproute2 also.
Thanks

- JC 05:05 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: SocketCAN configuration
- Apparently the filesystem ip utility isn't using busybox.
- JC 04:37 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: SocketCAN configuration
- It would be the busybox that comes in the TI filesystem we ship with the devkits.
- FF 04:32 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: SocketCAN configuration
- Thanks for the quick response. What version of busybox are you using?
Thanks,
Fred - JC 03:24 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: SocketCAN configuration
- I used the busybox ip utility to configure can when I last tested it.
I found the following script which I created to configure can.

See the following cantest script which is used to test can by connecting... - What is the recommended method for configuring a socketCAN port on the MitySOM3354? I have tried using the iproute2 utility as described in the TI instructions.

- Here is the command we run to create the jffs file for the original MDK. Where $root is the path to the extracted filesystem.
- BA 11:01 AM MityDSP-L138 (ARM9 Based Platforms) 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...

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 MityDSP-L138 (ARM9 Based Platforms) 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...

- JC 03:19 PM MityDSP-L138 (ARM9 Based Platforms) 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.

The above link lists the TTY and LinuxInput driver as what would be needed for keyboard input.

- Hi Tim
I am currently launching my application with the -qws flag, e.g. - TI 07:14 AM MityDSP-L138 (ARM9 Based Platforms) 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
/Tim - 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.

Excellent, that has definitely helped as I can now see /dev/0 after the following two commands (with FPGA loaded from uBoot).

- 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... - MJ 11:26 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: DVI Framebuffer (fpga i2c) problem

- GG 11:35 AM MityDSP-L138 (ARM9 Based Platforms) 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... - 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 ...

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.
