Ok I am slightly confused her on the pinmux signal directions. In the BB-BONE-AUDI-02-00A0.dts file we have all pins set to inputs fragment@0 { target = <_pinmux>; __overlay__ { bone_audio_cape_audio_pins: pinmux_bone_audio_cape_audio_pins {

[beagleboard] Adafruit BBIO Python library

Hi folks, Just a quick note to let you know I've spent some time tracking down the differences between 3.8 and later versions for the Adafruit BBIO Python library. I first noted this post https://forums.adafruit.com/viewtopic.php?f=49=91903=468811#p469266 which discusses that the 3.8

[beagleboard] Re: Fast Pin Toggling Using MMAP

Hi Frank! Your example controls one GPIO subsystem. The pins P9_11 to P9_18 are connected to two GPIO subsystems. That's why you cannot control all pins at 2.6 MHz. You'll have to find a set of pins connected to a single GPIO subsystem (either GPIO0 or GPIO1). As John mentioned, this is stuff

Hey, I had a look at the kernel source at github. From the code I would say the 8250 driver supports RS485. Only the "rs485-rts-active-high" flag from the device tree overlay seems not to be supported. But the same setting can be done via the struct serial_rs485 from user space. Also RS485
