Hello All;
I have a script that enables the other UARTs on the BBB, when I run it after the system has booted. The problem is I can't get the same commands to execute automatically when UBUNTU 12.04LTS boots. This is the bash file that works: serials.sh #!/bin/bash cd /lib/firmware/ echo ttyO1_armhf.com > /sys/devices/bone_capemgr*/slots echo ttyO2_armhf.com > /sys/devices/bone_capemgr*/slots echo ttyO4_armhf.com > /sys/devices/bone_capemgr*/slots echo tty01_armhf.com > /sys/devices/bone_capemgr*/slots echo tty02_armhf.com > /sys/devices/bone_capemgr*/slots echo tty04_armhf.com > /sys/devices/bone_capemgr*/slots cd ~ Here is the result: root@ubuntu-armhf:/# bash serials.sh root@ubuntu-armhf:/# ls -l /dev/ttyO* crw------- 1 root tty 249, 0 Jul 28 22:28 /dev/ttyO0 crw-rw---- 1 root dialout 249, 1 Jul 28 22:28 /dev/ttyO1 crw-rw---- 1 root dialout 249, 2 Jul 28 22:28 /dev/ttyO2 crw-rw---- 1 root dialout 249, 4 Jul 28 22:28 /dev/ttyO4 root@ubuntu-armhf:/# If I put the same commands in .bash_profile this is what I get: .bash_profile PATH=$PATH:/home/ubuntu/local/cloud9/:/home/ubuntu/local/cloud9/bin/ export PATH export NODE_PATH=/usr/local/bin/cloud9/node_modules # Required For Device Tree Overlays export SLOTS=/sys/devices/bone_capemgr.9/slots export PINS=/sys/kernel/debug/pinctrl/44e10800.pinmux/pins # Setup the other Serial Ports echo "Setting up ttyO1 - ttyO4" echo /lib/firmware/ttyO1_armhf.com > /sys/devices/bone_capemgr*/slots echo /lib/firmware/ttyO2_armhf.com > /sys/devices/bone_capemgr*/slots echo /lib/firmware/ttyO4_armhf.com > /sys/devices/bone_capemgr*/slots ubuntu-armhf login: root Password: Last login: Mon Jul 28 22:25:16 UTC 2014 on ttyO0 Welcome to Ubuntu 12.04.4 LTS (GNU/Linux 3.8.13-bone20 armv7l) * Documentation: https://help.ubuntu.com/ Setting up ttyO1 - ttyO4 [ 25.020726] bone-capemgr bone_capemgr.9: failed to load firmware '/lib/firmware/tt-00A0.dtbo' -bash: echo: write error: No such file or directory [ 25.050049] bone-capemgr bone_capemgr.9: failed to load firmware '/lib/firmware/tt-00A0.dtbo' -bash: echo: write error: No such file or directory [ 25.079348] bone-capemgr bone_capemgr.9: failed to load firmware '/lib/firmware/tt-00A0.dtbo' -bash: echo: write error: No such file or directory root@ubuntu-armhf:~# ls -l /dev/ttyO* crw------- 1 root tty 249, 0 Jul 28 22:27 /dev/ttyO0 The .dtbo files are in /lib/firmware/ or the bash script wouldn't work. Is there somewhere else I should put the commands ? Thanks. Bill "No one could make a greater mistake than he who did nothing because he could do only a little."
