1 year ago Quick test before bed time.
So indeed this version is booting properly. Yet, maia-httpd does not start.
I thus tried to launch it manually:
# ./maia-httpd
Error: ad9361-phy IIO device not foundJust in case it helps:

There are reports that the Maia SDR firmware v0.1.0 doesn't work with a Pluto rev. C. After the firmware is flashed, the Linux kernel doesn't seem to boot completely.
On closer inspection of the differences between Pluto rev. B and rev. C, I think that the problem might be that the Device Tree for Pluto rev. C defines a Xilinx SPI controller in the PL. This is not present in the Maia SDR FPGA design, so the kernel will hang the AXI bus when trying to talk to the SPI controller.
Here is a
pluto.frmfile for the Maia SDR firmware with the SPI controller entry removed from the Pluto rev. C Device Tree. It is a zipped file because of Github file type restrictions. It needs to be unzipped before flashing.pluto.frm.zip
I don't have a Pluto rev. C to test this at the moment, so reports about whether this works would be helpful.
