Hi Guys, I have a problem. What I have done so far for enabling the UART1. Downloaded, dtb-rebuilder for Kernel 19, outcommented the two lines for tty2, make, make install and reboot.
After reboot I have those results: *cat /sys/kernel/debug/pinctrl/44e10800.pinmux/pingroups* *pin 84 (44e10950.0): 48024000.serial (GPIO UNCLAIMED) function pinmux_uart2_pins group pinmux_uart2_pinspin 85 (44e10954.0): 48024000.serial (GPIO UNCLAIMED) function pinmux_uart2_pins group pinmux_uart2_pins* *dmesg |grep serial *says: *[ 2.321838] omap8250 44e09000.serial: ttyS0 at MMIO 0x44e09000 (irq = 154, base_baud = 3000000) is a 8250[ 2.340061] omap8250 48024000.serial: ttyS2 at MMIO 0x48024000 (irq = 155, base_baud = 3000000) is a 8250* *Uname -a:* *Linux arm 3.19.0-rc31.2 #2 Fri Apr 17 08:00:32 UTC 2015 armv7l GNU/Linux* I think the pins are muxed correctly. But I thought the name for UART is ttyO2 for UART2 and not ttyS2. Has it changed with the Kernel Upgrade?? Or do I have to activate it somehow? Thank you in advance!! greetings Benjamin -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
