Hello, I am a novice when it comes to using the BBB. I have a revC and I
have just started to play around with it. I have just updated the board to
the latest image from the beagleboard.org/latest-images web site, which is
the Debian 8.3 "Jessie" build from 24-Jan, and I cannot get anything to
work via Bonescript on this build.
Upon unboxing I had previously played around a little with blinking the
on-board LEDs as per the "getting started" tutorial. Using Cloud9 I was
able to run the LED3 1s "blink" cycle, set one of the GPIO pins to output a
PWM wave, etc. Due to repeating problems when connecting a USB hub (for
hooking up mouse & keyboard) I decided to upgrade the OS image to the
above.
After performing this task, I am happy to report that the USB hub now works
perfectly. However, nothing else does! And by this I mean that I cannot
execute anything via Bonescript. Say, for example, I browse to the "getting
started" tutorial at 127.0.0.1. There is a box that you can click that
should turn on all 4 user LEDs for 2s. This box is grayed out and does not
work.
And if I go to Cloud9 and try to execute anything, I get the following
output in the debugger:
+++++

+++++
It seems to me like this image is not setup to run Bonescript out of the
box. Can anyone tell me what is going on? Should I switch to some different
OS image, or is there a way to fix this one, or am I making some user
error...?
I am not sure how relevant the following information is. But I will also
mention that I verified the downloaded SD card image with the SHA-256 hash,
and it was OK. Also I have programmed the eMMC from the SD card & am
booting off that (as opposed to running directly from the SD card). And
finally I have done nothing to modify the image in any way.
Thanks in advance.
