I'm glad you got it working. I'm not sure the exact difference between what you did and the official instructions, but it may be that your "direct copy" approach may not have brought over all of the libraries or extensions th... - HB 03:05 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Java Runtime Environment for MitySOM1810f

Yes, sure, I know this.
But for now, I prefer modifying the kernel:

pre tag: - MK 02:21 AM MitySOM-5CSX Altera Cyclone V Software Development: RE: Increase POSIX message queue size

The lines start with '*', but then text formatting makes lists out of that :-/
(maybe you could re-edit?)

Dan - JK 12:27 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: Using PREEMPT_RT on MitySOM 5CSX Dev Board
- Problem solved! Thank you so much.
I'm now carefully stepping through adding additional relevant nodes from the MitySOM 5CSX device tree. - HB 09:04 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Java Runtime Environment for MitySOM1810f

Thank you both for these great info, I will try to generate the JRE.
I will let you know about the results.

- Hello,
One quick question, are the ! before the * meant to be there?
I will try to reproduce this issue tomorrow, I'll report back once I do.
Dan - DV 08:04 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: Using PREEMPT_RT on MitySOM 5CSX Dev Board
- You are also correct in using the uBootMMCEnv.txt from our git repo. The other one is a much older version, which should actually do the same thing but the one from the git repo is the latest and greatest.

I was able to reproduce your problem and I've found the issue. Between our 3.16 kernel and the 4.1.22 kernel it looks like some of the device tree attributes for the altera pio core were changed. Also the updated device tree do... - DV 05:38 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: Using PREEMPT_RT on MitySOM 5CSX Dev Board
- Hi Jared,
From what you've seen it looks to me to be an issue with the 4.1.22 kernel. I've looked at qsys/dts and they look fine. Tonight I will build the 4.1.22 RT kernel and try that on our dev kit (using everything from our dev kit... - JK 05:31 PM MitySOM-5CSX Altera Cyclone V Software Development: RE: Using PREEMPT_RT on MitySOM 5CSX Dev Board

Would you mind posting your .qsys file and .dts?
I'll take a quick sanity check,

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

Hector - JC 11:40 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Java Runtime Environment for MitySOM1810f
- 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,

- 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.

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