Hi All, I am a new bee in BBB too, but have some knowledge about the serial device and data-acquisition. I have read all the emails below, and understood the code. The problem is the command to link the UART4 to /dev/tty failed.
debian@beaglebone:/var/lib/cloud9$ echo BB-UART4 > /sys/devices/bon e_capemgr9/slots bash: /sys/devices/bone_capemgr9/slots: No such file or directory Cannot find the bone_capemgr in the /sys/devices in this board. Please advice. ls -l /sys/devices/ total 0 drwxr-xr-x 5 root root 0 Sep 28 17:22 armv7_cortex_a8 drwxr-xr-x 3 root root 0 Sep 28 17:22 breakpoint drwxr-xr-x 22 root root 0 Sep 28 17:22 platform drwxr-xr-x 3 root root 0 Sep 28 17:22 soc0 drwxr-xr-x 3 root root 0 Sep 28 17:22 software drwxr-xr-x 6 root root 0 Sep 28 17:22 system drwxr-xr-x 3 root root 0 Sep 28 17:22 tracepoint drwxr-xr-x 12 root root 0 Sep 28 17:22 virtual Lingling On Thursday, March 27, 2014 at 4:59:00 PM UTC-4, Mark A.
