running BeagleBoard.org Debian Image 2015-03-01
startup (from
https://learn.adafruit.com/adding-a-real-time-clock-to-beaglebone-black/set-rtc-time)
is invoked via;
systemd
bash script has a delay, increased it to 2 min still same non-running of the
PRU.
given the large delay; I have logged in and checked, program was not running
I executed it(via putty), and it ran 100% fine.
I killed the program, waited for the start-up script to kick in
the start up script executed the program and its running fine.
kinda not sure where to next?
to recap
I login(via putty)
ps ax|grep myprogam
does not show my program running
I execute program
cd /home
myprogam &
I kill the program
kill -9 myprogramPID
2 minutes pass, and the program executes and runs 100% good.
If I *restart *login(via putty) and wait 2 minutes, the program executed but no
PRU activity.
I do get, error below consistently upon boot-up, but does not seem to effect
the operation of the PRU.
root@beaglebone:~# dmesg|grep pru
[ 8.606803] omap_hwmod: pruss: failed to hardreset
