- DV 11:12 AM Software Development: RE: Using PREEMPT_RT on MitySOM 5CSX Dev Board
- Hi Jared,
Looking at the sockit dts(https://github.com/altera-opensource/linux-socfpga/blob/socfpga-4.1.22-ltsi-rt/arch/arm/boot/dts/socfpga_cyclone5_sockit.dts) I see they are setting skews for the data clocks for the RGMII phy. We d... - JK 10:38 AM Software Development: RE: Using PREEMPT_RT on MitySOM 5CSX Dev Board
- Hello Dan,
I've been performing more testing on the Altera 4.1.22 LTSI RT branch.
Physical setup: MitySOM 5CSX H6 HYA dev kit connected to network via Ethernet (J500).
Altera 4.1.22 LTSI RT does indeed get an IP address, but the...

- DV 10:30 AM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot
- Hello Steve,
There was a bit of stability issue with the I2C interface to the HDMI transmitter IC. I thought my newest build of the demo had the stability issue ironed out though, let me take try it here again and I'll post back with ... - Hello,
I'm trying to run the HDMI output image provided on the wiki. I haven't modified anything just written the image to an SD card.
When booting, the splash screen sometimes shows up, but usually doesn't. I'm also intermittent... - DV 10:24 AM Software Development: RE: Using PREEMPT_RT on MitySOM 5CSX Dev Board
- Hi Jared,
Glad to hear that worked for you! If you run into trouble getting your defconfig/dts setup how you want just let me know.

- Hello Dan,
Thanks for pushing the dizzy (1.7) branch. I've successfully gotten to the same point you did in your first reply via a Yocto build (Altera Linux 4.1.22 LTSI RT is booting and receiving an IP address, but still need to modi...

- Hi Jared,
Sorry for the delay.
I just pushed a dizzy(1.7) branch to our git repo: http://support.criticallink.com/gitweb/?p=meta-mitysom-5csx.git;a=shortlog;h=refs/heads/dizzy
This will use gcc 4.9.1 for the toolchain, which shoul...

- JK 03:27 PM Software Development: RE: Using PREEMPT_RT on MitySOM 5CSX Dev Board
- Hello Dan,
I proceeded to try to use Yocto to build the Altera 4.1.22 LTSI RT kernel based on your suggestions above.
Unfortunately, the compilation of the kernel is erroring out because of an incompatible GCC version. The followin...

- DV 11:55 AM Software Development: RE: Using PREEMPT_RT on MitySOM 5CSX Dev Board
- Hello Jared,
That sounds like a perfect approach. For building the file system we do use yocto, which as you saw is pointed to use the 3.16 kernel. Now depending on how manual you want to do this I can suggest a few options.
Probab... - JK 10:26 AM Software Development: RE: Using PREEMPT_RT on MitySOM 5CSX Dev Board
- Hello Dan,
I've been going through the instructions on the Wiki to get an SD card image of my creation working. I'm starting with the 3.16 kernel version provided by Critical Link to get a handle on the process of building an SD card ...

- Hello Jared,
I did a quick test here and was able to boot altera's 4.1.22 ltsi rt kernel using the MitySOM-5CSX dev kit. I used the socfpga_defconfig and socfpga_cyclone5_sockit.dts. I didn't do an extensive test but was able to boot ...

- Context: My company recently purchased some MitySOM 5CSX Development Boards and would like to use them on a current project. This project likely has the need for a real-time operating system. I want to start by using Linux with the PREEM...
