- Hi Dan,
Our hardware engineer just noted a significant difference between two versions of uBootMMCEnv.txt listed on Critical Link's website regarding the MitySOM 5CSX.
One is in the git repository for the development board, and it'... - JK 12:16 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: Using PREEMPT_RT on MitySOM 5CSX Dev Board
- Hi Dan,
Requested files attached; let me know if I'm missing anything (e.g., FPGA source code).
Also, not sure if this is related to the problem... whenever I have one PIO in the DTS, it shows up as /sys/class/gpio/gpiochip480. Tha... - DV 12:04 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: Using PREEMPT_RT on MitySOM 5CSX Dev Board
- Hi Jared,
Would you mind posting your .qsys file and .dts?
I'll take a quick sanity check,
Thanks

- According to this bug report, the "Linux ARM 32 Hard Float ABI" only supports ARMv7 instructions. The L138 is a ARM9 which uses ARMv5 instructions. It also mentions their used to be a "Linux ARM 32-bit Soft Float ABI" version which wou...

- Thanks Jonathan,
Do you think that could be possible to have some compatibility with the JRE from JDK for ARM microprocessors?

- Note that java version 1.5 is very old. You may have to build jamvm manually to get something more update.
- JC 11:39 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Java Runtime Environment for MitySOM1810f
- I don't believe anyone has. A quick search of `opkg list` shows the availability of jamvm 1.5.5 which is apparently a lightweight java vm.
http://jamvm.sourceforge.net/ - Hi!
I would like to run some Java template programs in the MitySOM1810,
*Have anybody done something like this before?*
Thanks,
Hector

- Addendum: any single PIO (0 through 3) can be enabled in the DTS and the system will boot, but including more than one causes the boot process to hang.

I did a bit more experimenting with including a subset of the hps_lw_bus sub-nodes. I confirmed with the Verilog developer on our team that the FPGA image file I'm using has the PIO cores and System ID core present in the stoc...

Sorry for the delayed response.

The hps_lw_bus node and all sub nodes are for any FPGA related logic that is attached to the HPS Light weight bridge. For the dev kit there are 3 PIO cores and a System ID core attached to this bus.

I am trying to communicate using the SPIM0 on the HPS with 5CSE-H4-3YA. SPIM0 HPS I/O Set 0 is selected in the QSYS project and the correct multiplexing seems to be in effect for the use of SPIM0.CLK, SPIM0.MOSI, SPIM0.MISO, SPIM0...

I'm now working to create a custom DTS, using socfpga_cyclone5_sockit.dts as a starting point, which incorporates elements of the MitySOM 5CSX DTS. When using the 4.1.22 LTSI RT kernel with socfpga_defconfig and socfpga_cyc...

The switch it's usually plugged into is 10/100.

- AD 04:27 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: Ethernet not coming up
- I'm not sure why it would fail like that, then recover without any real changes. The HPS_GPIO28 controls the Ethernet PHY Reset. If this was set low, the PHY would be held in reset. That being said, the boot log shows that this GPIO s...

- DV 10:58 AM MitySOM-5CSX Altera Cyclone V FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot
- That's a good idea Mike, it looks like the kernel defaults vram to 4MB but for this framebuffer 8MB+ is required. I'll try setting it higher and see if I can get 1080p working today.
Thanks,
Dan

I'm testing this now. Hopefully it's just the mods to the device tree/qsys project. I'll update once my build is finished and (fingers crossed) I'm able to get video.
