Re: [beagleboard] PHP5 pre-installed

Williams, I wanted to get an SD card image *pre* installed with php before I insert the card into BBB. The command you have provided is to get the php after loading the SD into BBB. I am able to install the php package after I load the sd card in the BBB and then do the command 'sudo apt-get inst

[beagleboard] PHP5 pre-installed

Hi All, I have a doubt on how to package the php5 within the SD card image created to load in Beagle Bone Black. I have been following the instruction on https://eewiki.net/display/linuxonarm/BeagleBone+Black to get the micro SD card image. I use the default Debian 8 for the Root File System.

Re: [beagleboard] BBB not booting after upgrade

There is nothing obvious from the kernel log messages I've seen there. But what you could do is log into the system via your USB to serial adapter, and see what the state of various device interfaces are from the running systems standpoint. The "problem" could be something as simple as a configurat

Re: [beagleboard] BBG fried. Hint needed to undestand why.

Whenever you have separate systems that may power up at different times or the I/O configuration is unpredictable, then you should always use tristate buffers so that you don’t drive I/O until it is ready. Also, some GPIO are also used for boot configuration and these pins should not be driven d

Re: [beagleboard] BBG fried. Hint needed to undestand why.

Thanks @john3909. This is to avoid having external power applied to the GPIO pins of the BBB/G before is booted up which can damage the board right? I suppose that was the the problem with my fried BBG. This should also apply with a single Tx board and a single Rx board configuration rigth

Dhanesh, netcat is pretty much a general purpose networking tool. It can take stdin as input via using the pipe symbol at the command line, as well as pipe that input on the opposite end to stdout. So as an extremely simple example: client side: $ nc -l -p 5000 > /path/to/somefile This will take
