I’m really trying to avoid reboots: I’m designing a coprocessor which will do various various functions, so need to be able to reprogram it swiftly.
However, @Fabian_red has posted this Load fpga rbf from device tree overlay example? - #5 by Fabian_red which look very promising. It appears that the HPS can definitely do it through the fpga_manager: Cyclone V manual says:
The FPGA manager provides the following functionality and features:
- Full configuration and partial reconfiguration of the FPGA portion of the SoC device
- Drives 32 general-purpose output signals to the FPGA fabric
- Receives 32 general-purpose input signals from the FPGA fabric
I’ve also found a thing which appears to be this exact thing:
root@de10-nano:~# cat /sys/class/fpga_manager/fpga0/state
operating
So I’m optimistic! Will post any results I get.
Kind regards,
Jonathan.
