Hello,
I am working on a project that will be deployed in the field with an FPGA that will not be able to be plugged into a typical desktop computer running Quartus. However, I may have to push software updates to the FPGA remotely. I am currently planning to use the Terasic DE0 Nano with the Cyclone IV, but may instead use the DE10 Nano SoC with the Cyclone V SoC depending on design requirements. The system will also have a Raspberry Pi 3 Model B v1.2 or greater. Is there a way for me to compile a .jic file on my master computer, sftp it to the Pi, and then install it on the FPGA?
Thanks in advance.
Hello,
this question is probably out-of-date, so I hope that following response will help those looking for answear.
The right way to remote change of content of FPGA is use of DeviceTree overlay:
- compile new design with Quartus Prime to get SOF file,
- convert SOF file to RBF file,
- tranfer RBF file to SoC (e.g. via FTP protocol),
- use DeviceTree overaly for ‘fpga-region’ node.
Linux Driver of FPGA Manager applies the new design to the FPGA.
The only problem could be a form of DeviceTree blob, which would differ a bit design to design.
Many threads here, at forum.RocketBoards.org, discuss the solution, so it will be easy to find it. Moreover, the documentation of Linux kernel (see directory /Documentation of its source code) contains a description, how it all works.
Best wishes
