Hi, I recently obtained a "Rev C" version of Pluto, and used u.FL connectors to pin out the 2nd Rx and Tx channels. I've updated my firmware to the latest (0.33). I am trying to read data from both Rx channels, but I've run into two problems:
1. The first problem is that the "fw_setenv mode 2r2t" doesn't seem to stick.... After reboot, it always reverts back to 1r1t. I'm following these instructions:
And here's is what I get after reboot:
So then I re-enter the fw_setenv mode 2r2t command, and then it reports as set. But if I reboot again, it goes back to 1r1t
2. The second problem (and probably related to the first) is that pyadi-iio doesn't seem to recognize the 2nd Rx channel. Here's what my program looks like:
# Create radio sdr = adi.ad9361(uri='ip:192.168.2.1') samp_rate = 20e6 '''Configure Rx properties''' sdr.rx_enabled_channels = [0, 1] sdr.sample_rate = int(samp_rate) sdr.rx_rf_bandwidth = int(10e6) sdr.rx_lo = int(2.4e9) sdr.gain_control_mode_chan0 = "manual" sdr.gain_control_mode_chan1 = "manual" sdr.rx_hardwaregain_chan0 = int(30) sdr.rx_hardwaregain_chan1 = int(30)
However, anything that references "chan1" gives me error.
