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

- No, '!' are my faults, ie. due to my poor knowledge about formatting.
The lines start with '*', but then text formatting makes lists out of that :-/
(maybe you could re-edit?)

- Glad to hear that was the solution!
Dan - JK 12:27 PM 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.

- 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 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.

- Jared,
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 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 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

- JK 12:02 PM Software Development: RE: Using PREEMPT_RT on MitySOM 5CSX Dev Board
- 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...
