I replaced the dongle - didn't help. I replaced the Pi PSU - didn't help. I tried all the usb ports on the Pi. When I switch ports I get 1 - to a few readings, then it stops again. Maybe the usb ports on the Pi (or the usb huv) are broken? I switched to a Pi4, testing both donbgles - no dice. Testing with one dongle on my c2 workstation says it can be noise., ok, nothing to do about that. 2026-05-25: mmcsd0s2a - rootfs - hmm, when I run rtl_433 via `service rtl_433 start` it runs, but doesn't publish any mqtt messages. Strange. ok, I'll just do `sudo rtl_433` then, that way works. 2026-05-25: mmcsd0s2a - rootfs - enable rtl_433 ```sh root@rtl3:~ # sysrc rtl_433_enable="YES" rtl_433_enable: -> YES ``` 2026-05-25: mmcsd0s2a - rootfs - info about the microSD card from dmesg ```sh root@rtl4:~ # dmesg | grep mmc mmc0: on sdhci_bcm0 mmc0: Card at relative address 1 failed to set high speed timing mmcsd0: 63GB at mmc0 0.4MHz/4bit/65535-block ``` 2026-05-25: I created this page. 2026-05-25: mmcsd0s2a - rootfs - booting the **FreeBSD 14.4-release-p5** microSD card that I configured on the Pi 4. ```sh root@rtl4:~ # freebsd-version -ku 14.4-RELEASE-p5 14.4-RELEASE-p5 ``` kernel ```sh root@rtl4:~ # uname -a FreeBSD rtl4 14.4-RELEASE-p5 FreeBSD 14.4-RELEASE-p5 GENERIC arm64 ``` it seems the card has a problem in this machine too.
