Description Benedict Reuschling freebsd_committer 2017-06-16 10:06:05 UTC
The Raspberry Pi 0 W does not boot with the latest ARMv6 RPI-B SD-card image. The same image works successfully on the Raspberry Pi 0 (Camera and no camera edition) and boots to a login prompt. The W version does not seem to go beyond the U-Boot prompt, as reported here:


On the RPI0 without WiFi/Bluetooth, the next kernel message after the U-Boot prompt is "starting USB", so maybe there is something wrong or different in the RPI0-W? Unfortunately, I can't enter anything at the U-Boot prompt, so it is difficult to enter any diagnostic messages.

I can test images/patches and report back my findings. I can also bring the device to BSDCam or other conferences for hands-on tests.

I suggest to add 


to the config.txt file in the MSDOS partition.

Thanks for the tip, Helge. Did you try that yourself or did you read it somewhere?
Ilya, can you confirm that this works on the RPI 0 W?

I found this is needed for my RPI-B (which is based on the same BCM2835 as the Zero and Zero W). Without explicit device tree, my RPI-B throws the same error. Note that both settings are indeed needed.

These two lines are in the config.txt of the 11.1-RELEASE images for RPI-B (originating from the sysutils/rpi-firmware port) but for some reason had been removed recently.

I suspect this is related to bug #218344 which should be fixed by base r322694 in CURRENT and base r326951 in 11-STABLE.
