[ 0.210444] omap_uart 44e09000.serial: did not get pins for uart0 error: -19
[ 0.210719] 44e09000.serial: ttyO0 at MMIO 0x44e09000 (irq = 88) is a OMAP UART0
[ 5.035048] gserial_setup: registered 1 ttyGS* device
[ 1763.473407] 48022000.serial: ttyO1 at MMIO 0x48022000 (irq = 89) is a OMAP UART1
But now I have other doubts.
Why there are only 2 serials ?
How can we access other if they aren’t mapped /dev/tty??
If you’re using the Adafruit BBIO library, it creates the necessary UART devices in the device tree on the fly (by placing its own ADAFRUIT-UART files in /lib/firmware and writing to /sys/devices/bone_capmgr.*/slots).
So it really is pretty easy to use – it’s designed for non-tech types to get maker projects running on the BBB. Surprised you asked over here rather than in the more-relevant Adafruit forum on BBIO.
This is my first time developing with beaglebone black.
Even though I knew python, I never used ADAFruit library.
So I ask here because of lack of understanding on both things.
I’ll try again when have more time,
but so far, I need to use this hacks to enable UART
because I’ll use them with JAVA, and the python code I used was just a test to check UART hardware.
Thank you sir… I have WiFi dongle used to my computer.Can I used same wifi usb dongle for BBB? Because of I tried But It did not connect. How to connect WIFI usb for my BBB?
Thank you for your answer sir…
I have been developing IoT home automation using beaglebone black with controlling by using android app. I have been using python and I got library file such as PWM,ADC,GPIO,UART,EMAIL but I didn’t get android app library… How to include android app ? Could you help me?
