Dear all,
I am trying to enable SPI1 on the BBB wireless.
When I added only uboot_overlay_addr5=/lib/firmware/BB-SPIDEV1-00A0.dtbo, both spidev0.0 and spidev0.1 appear under /dev/.
I don’t know why I’m getting SPIDEV0 although I enabled SPI1 but at least I see a SPI device.
The big problem occurs when I enabled both SPI0 and SPI1 in /boot/uEnv.txt with all else unchanged.
( In /boot/uEnv.txt like this:
uboot_overlay_addr4=/lib/firmware/BB-SPIDEV0-00A0.dtbo
uboot_overlay_addr5=/lib/firmware/BB-SPIDEV1-00A0.dtbo
I don’t see any SPI device under /dev/. Seems like enabling SPI0 somehow disabled all SPIs.
Here is the serial message from booting: looks like both SPIDEV overlays are loaded.

It turns out that the SPI problem was (seems like) due to something inside the minimum image.
As my colleague suggested, I tried using the Debian Buster IoT image and SPI (both 0 and 1) were enabled out of the box.
I upgraded the kernel from 4.19 to 6.1 and SPIs were still fine.
