Trying to use an open source project (FOS FPGA OS) based on PYNQ 2.3, I’m trying to reconfigure the FPGA PL. I have generated valid .bin, .bit and .hwh files that I have tested using the PYNQ Overlay libraries.
The project in question uses python to reconfigure the FPGA with the following code snippet:
with open("/sys/class/fpga_manager/fpga0/firmware", "w") as binout: binout.write("./bitstreams/static_full_vadd.bin") binout.close()
Edit: The given paths are valid
On the PYNQ’s jupyter notebook, this returns the following error:
FileNotFoundError: [Errno 2] No such file or directory
Since this supposedly uses the inbuilt Xilinx FPGA Manager, I tried to echo the bin file in fpga0/firmware, wich didn’t return anything (neither an error nor the message
fpga_manager fpga0: writing system_wrapper.bit.bin to Xilinx Zynq FPGA Manager). I could not test the bin this way however.
I know the PYNQ project would rather recommend using the Overlay library to reconfigure the PL, but I was worried about this issue since I thought I could still reconfigure the FPGA this way.
Is this a know issue, or is there any steps that I missed (such as configuring the Xilinx FPGA Manager) to make it work on PYNQ?
Sorry if my question is out of the PYNQ project’s scope, feel free to close the topic if it is
PYNQ version: 2.3
