Program the FPGA from Linux version 4.1.22-ltsi

[Jump]

I use CycloneV Soc.

I would like to program the FPGA from Linux.
Linux version 3.10-ltsi was able to do by the method of the following page.
https://rocketboards.org/foswiki/view/Documentation/GSRDProgrammingFPGAArrowSoCKitEdition

However, it can not be done in version 4.1.22-ltsi.
Because device file “/ dev / fpga” does not exist.
How do I program the FPGA from Linux in version 4.1.22-ltsi?

best regard,

You should have a look at this post here:

Missing /dev/fpga0 device on DE0-nano-SoC

I’ve just compiled the Linux 4.1 LTSI kernel and Poky. I’m able to boot the kernel on my DE0-nano-SoC board, using the default device tree that comes with the kernel. dmesg seems fine so far, no errors. Though /dev/fpga0 is missing. I can also see successfull registering of the Altera FPGA Manager driver: Jun 21 14:44:32 cyclone5 kernel: [ 1.985422] fpga_manager fpga0: Altera SOCFPGA FPGA Manager registered Jun 21 14:44:32 cyclone5 kernel: [ 1.992306] altera_hps2fpga_bridge ff400000.…

Thank you for the infomation.

I cannot understand the overlay.dtb file.
I’d like to know more detail for the file.
