Working with an RFSoC4x2, I am trying to merge the features of RFSoC-MTS and RFSoC-PYNQ by modifying pynq.overlays.base.BaseOverlay and adding modules and variables from the RFSoC. The key changes are shown here (rfsoc_array/array.py · 73add84a07c26f92f6271ccee8cfb7120c23d40c · hpowell-umass-ece-phd / RFSoC-Array · GitLab), reflecting a set of IP blocks added in Vivado. This modification is intended to be non-invasive, allowing for backwards compatibility to the base.bit for the 4x2. However, when trying to transmit a 915 and 920 MHz tone from two antennas facing a receiving patch array, the tones are not received. Reverting the changes shown in this git diff (commenting init worked, uncommented adc_capture lines to test (73add84a) · Commits · hpowell-umass-ece-phd / RFSoC-Array · GitLab), the tones are transmitted and received successfully. I am wondering if something about these sets of lines run in the class init, or the method memdict_to_view() that they call, is resulting in either the transmit IP failing, or some issuye with the RFDC itself. The one meaningful error I get is
ADC setup unavailable for tile <xrfdc.RFdcAdcTile object at 0xffff609d9540>.
when I try to initialise my custom Overlay class. Any help, suggestions, or questions will be appreciated. Thanks.
