- Hello,
I would recommend using our newer krogoth branch in order to build the the 4.1.22-ltsi-rt kernel. I've been able to use it in conjunction with altera's meta layer to build the the rt kernel.
I have attached a few files that ...

It doesn't look like we ever created that guide. I'd recommend looking at the provided source files as examples.

You'd want to extract the MDK filesystem, update the files and then generate the jffs2 image file. NOTE: We also generate a new tarball which we can archive o... - Hi,
I have a custom board with
1) MityDspl-138F module (with FPGA)
2) No Ethernet port
3) UART,USB,SD CARD interface

The company I work for has just started working on the MitySOM 5CSX Development board, and in our system we need to use the preempt-RT version of the kernel.
Currently we have a working project using the Terasic DE0-Nano-SoC eval ...

I've been working on a MityDsp-L138F with Linux Ångström.
I'm able to use the 128-KB shared RAM for inter-processor communication between the two cores, with ARM running Linux and DSP running baremetal. I want to send interrupt...

- Greq, good point WRT the inouts... thanks for bringing it up. In our case they were going to be dedicated outputs. Either way it's great that CL supplies those cores, no doubt they will be utilized. Regs, Tom
- GG 09:39 PM MityDSP-L138 (ARM9 Based Platforms) FPGA Development: RE: Alternate GPIO Control
- Hi Tom,
One concern I have regarding your proposed approach would be the case of your GPIOs needing to be run-time configured as inputs or outputs. Configuring your FPGA passthrough ports to be inouts may be sufficient, but you may a... - Hi,
Direct GPIO control from the L138 is pretty nice to have. In our current task we need a number of GPIOs, more then what is available on the expansion connections when considering the other L138 functions we are using. The ability... - JC 02:28 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: How to activate splash screen

- JC 02:27 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: How to activate splash screen
- The LCD requires the fpga to be programmed if your using a L138 with fpga. Perhaps that's whats holding the LCD off until end of boot.

We have used these (https://www.digikey.com/products/en?keywords=87759-5050) on a couple of our expansion boards for the Industrial IO board. Note that they are surface mount headers.

- On the MDK 2014 filesystem, psplash is started first thing during rcS. I don't have my dev kit setup for a display right now so can't test that.
- Hi everyone,
I found psplash in the root file system and currently able to modify the screen.
However, I can't activate it in the boot process. Can you please provide some hint how to do it?

It's the opkg update that I needed to execute. Ok, so now there are quite a few pulseaudio pkgs that are listed, which is good. Also the commands you listed, their output matches what you have.

Hmmm a check here doesn't list pulseaudio. I'm pretty sure that I flashed on this board the mity-omap-full.jffs2 dated 2014-01-13. It lists the fpgautil "trunk+svnr2992-r7" and fpga-driver-modules "trunk+svnr2992-r51". ... - JC 03:50 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: creating a new rootfilesystem

Thanks. Our immediate task is to add pulseaudio to our MityDSP system, we will be integrating some external codecs shortly. Since pulseaudio is not a pkg that came with the mityimap-full, we need to add it. I do have some yoc...
