I tried to generate the device tree file from the sopcinfo file produced by quartus.
I used the following command
$ sopc2dts --input mityarm_5csx_dev_board.sopcinfo --output socfpga.dts
And I got a statement like this

05:20 PM Software Development: Interrupt & Device Tree

Hi,
Do you guys have any example on how to handle a interrupt? I have it set up in Qsys, where I have a FIFO sending its interrupt signal to the HPS. But how do I handle it on the software side.
I read that I need device tree to se... Anonymous

Thanks Mike,
Makes sense. I have a Terasic USB Blaster as shown in the attached PDF file.
What's the best way to interface the USB blaster to the white breakout connector on the MityArm Board?

Hi Rich,
This is an answer from our Altera FAE:
_You can’t create .rbf files from time limited sof files. The concern is that you could put the .rbf in flash and reconfigure every hour to avoid paying for the IP. Some our 3rd pa... Michael Williamson

RB 02:04 PM FPGA Development: Time limited SOF file question

I built a component into the FPGA that includes an instance of the Altera FIR II compiler.
At the end of the build, the final output is named: mityarm_5csx_dev_board_time_limited.sof
The file converter utility does not seem to be wil... Rich Bagdazian

Hi Greg,
I have no problem with the software wihtout first sending the command to enable the SDRAM. The data that I get from memtool matches the data that I get from my software.
Thanks!

Hi Jack,
Do you run into any problems if you use your software without first sending the command to enable the SDRAM? We'll try to get you an explanation for what you're seeing and in the mean time try using your software without run... Gregory Gluszek

Hi,
I managed to read memory into a file but we got another problem.
We are following your example - write to hps memory. In that example a command has to be issued in order to write to memory via the FPGA
