Okay, here's a summary of the provided transcript in a self-contained bullet list format, including timestamps, important details, and key takeaways:

FPGA Meetup - February 18, 2025: Progress, Challenges, and New Collaborations

• 0:00:02 Introduction: The meeting focuses on discussing progress, future plans, roadblocks, and resource needs related to FPGA projects.

• 0:00:25 Aaron's Update (OpenCPI & AD9371): Aaron is working on generalizing OpenCPI support for the AD9371 transceiver, aiming to extend compatibility beyond the Edis n310 to other platforms like the zc706. This involves adapting device workers and utilizing the JESD interface, potentially benefiting other projects like the high Farah.

• 0:02:31 Portability Goals Goal is to make the AD9371 work reproducable onto any other platform, including Zinc Ultra Scales.

• 0:02:53 Eris n310 vs x310: The n310 is network focused, the x310 is ADC and DACs directly.

• 0:06:11 Paul's Update (Pluto-to-Pluto Communication): Paul investigated issues with signal transmission between two PlutoSDRs. He ruled out frequency error as the primary cause by synchronizing them with an external clock.

• 0:07:52 RF Loopback Verification: Through systematic attenuation measurements, Paul confirmed that RF loopback on a single PlutoSDR is functioning correctly, indicating the issue lies in the independent receiver setup.

• 0:09:13 Pluto Reception: Can receive signal on the Pluto down to the threshold of the noise floor.

• 0:11:08 Remote Lab Status: The remote lab experienced a VM crash due to memory exhaustion during deep learning training, highlighting resource limitations.

• 0:12:01 Planned Outage: A planned outage is needed for software updates (Oowner Aid) but hasn't been scheduled yet.

• 0:12:30 Matthew's Update (MSK Design & Future Plans): Matthew reports limited progress on the MSK design. He plans to investigate the independent receiver issue and suggests adding spectral inversion capabilities to the design.

• 0:14:44 Proposed Experiment: A proposal to test streaming data (instead of the current timer-based approach) using the libiio streaming example is made to potentially identify issues in the radio setup.

• 0:17:10 IQ Sample Streaming: Discussion about streaming IQ samples from both the loopback and independent receivers to compare and identify differences that might explain the reception problem.

• 0:21:42 Suggested Test (Full Duplex): Matthew suggests a full-duplex test between two Plutos (transmit of one to receive of the other, and vice-versa) to rule out any dependencies on the transmitter affecting reception.

• 0:23:56 Daniel's Introduction: Daniel, an SDR engineer with experience at NASA and now working at AMD/Xilinx, joins the meeting. He expresses interest in contributing to the project and potentially bridging the gap between open-source efforts and industry practices.

• 0:26:18 Daniel's role: Daniel describes his role as milcom and satcom system architect at AMD.

• 0:29:03 Daniel's Background & Goals: Daniel highlights his expertise in DSP and FPGA implementations for SDR, his past interest in sharing NASA's dvbs2 code, and his current focus on improving accessibility to AMD/Xilinx tools and devices.

• 0:30:53 Open Source Advocacy: Discussion on the challenges of open-sourcing government-developed code and the importance of advocating for open-source policies.

• 0:36:57 Virtualization Discussion: Daniel raises the topic of virtualization, extending beyond traditional CPU virtualization to include co-resident FPGA fabric. He inquires about the group's experience or interest in this area.

• 0:41:50 OpenCPI Introducted: Aaron brings up the open source project openCPI, which helps enable hardware acceleration.

• 0:47:09 Current Project Focus: The most active project is the Uplink (Opulent Voice) for the space project, using minimum shift keying (MSK). The downlink (dvbs2) and payload multiplexing are also areas of ongoing development.

• 0:49:39 Challenges with FPGA Development: Feedback is provided on the difficulties encountered in setting up the FPGA development environment, integrating IP, and obtaining technical support, particularly for a distributed, volunteer-based organization.

• 0:56:27 Summary of Meeting: Meeting covered a lot of topics, and plans to reconvene in a week.
