Raspberry Pi CM5 roadtest - Finally, the USRP is working

2026-10-20T10:00:25Z

In my previous article about SDR++ on the CM5, I ended with an unresolved issue: although UHD was correctly detected during the SDR++ build and the USRP source was included, I could not get my Ettus USRP B205mini-i to actually work with SDR++. I deci...(read more)

POST 8 A case in point...Red Pitaya STEMlab 125-14 PRO Gen 2 Starter Kit

2026-10-11T20:12:56Z

Recall from an earlier post, that I had ordered and then reordered a case for the Red Pitaya. The first case ordered from a local supplier, wasn’t compatible with the RoadTest unit. It would have been nice if compatibility was mention...(read more)

Raspberry Pi CM5 roadtest - SDR++

2026-10-08T21:00:13Z

In my previous CM5 RoadTest articles I covered the initial setup of the Raspberry Pi Compute Module 5 and the installation and testing of the RTL-SDR. The next step was to try SDR++, one of the more versatile SDR applications available for Linux. A...(read more)

Raspberry Pi CM5 - Frigate NVR Hailo-8L Integration

2026-10-07T05:06:34Z

It's amazing that almost exactly 2 years ago, I had posted Using an RPi Camera Module 3 with the RPi5 AI Kit. At that time I was waiting for the Hailo-8L capability to be added to Frigate NVR application, so that I could replace the Coral U...(read more)

Raspberry Pi CM5 - Frigate NVR Initial Benchmarks

2026-09-29T04:07:09Z

I combined the thermal and power logging programs from the previous blog into a single program, cm5_power_temp_logger.py. I also examined the Frigate API to see what type of statistics were accessible through that interface. I think th...(read more)

POST 7 I'm really done this time… Red Pitaya STEMlab 125-14 PRO Gen 2 Starter Kit

2026-09-26T18:52:22Z

SPOILER ALERT: The Red Pitaya powers down if the USB-micro connection on the module is used. On of my troubleshooting attributes that can be either a blessing or a curse depending on the horse, is that I am persistent. In a previous post I used the t...(read more)

2026-09-24T17:39:35Z

Up to this point in my data collection posts for the kit, I've recorded little success. Knowing this device has both an oscilloscope and waveform generator I thought maybe I might find some wins in sampling those. Get the pun, sample, oscilloscop...(read more)

POST 4 I'm done beating a dead horse...Red Pitaya STEMlab 125-14 PRO Gen 2 Starter Kit

2026-09-21T21:55:15Z

My meaning of "beating a dead horse" is wasting time and energy on an task, that cannot be changed. My objective was to load the operating systems into the QSPI & eMCC module and eliminate the need for an SD card. A procedure to accompl...(read more)
