[Buildroot] [RPi 3B] ttyAMA0 serial port device doesn't exist on raspberry pi 3B

[Oscar Gomez Fuente]

Yes,

You are right. But with this overlay pi3-disable-bt-overlay.dtb, you only
disabled the BT module, because WiFi is over SDIO (I've found out the
solution to work properly the WiFi on buildroot, the next Monday I'll
report on the mailing list of buildroot). Right know I'm trying to check
everything on the RPi 3B, so the most important for me is the UART for
debugging. I don't understand why raspberry.org have left the RPi 3B
without a serial port for debugging (If you are using the BT module), I
suppose they have a good reason, but I don't know what. In my opinion, the
serial port for debugging is the most important thing on an embedded board.

Best regards.
