Re: Oracle Linux / Java Embedded

What is the reason for asking this? If it is for access to Java then Oracle Java is already included in the current Raspbian installs. My suspicion is that any version of Linux supplied by Oracle is likely only for x86 (Intel) based machines rather than ARM based machines like the Raspberry Pi, alth...

Linux and the Mac handle paths identically. Paths that start with / are always absolute, while those that do not are relative.

Re: Pi zero port question.

Not quite sure what you are asking? On the zero the micro usb power port has only the power lines connected (I.e. no data lines), while on the other port all lines are connected.

Re: Control Linux PC by connecting a Pi to it via USB

You do not mention what model of Pi?

For this to work you are going to need the Pi to be able to drive the USB port in ‘gadget’ mode. As far as I know only the pi0, Pi0W and Pi model A can do this.

Re: Protecting Proprietary software from being copied.

As many have said one has to work out the trade-off between effort and cost for security. Security that binds the software to the Pi serial number is probably a relatively simple thing to do and is pragmatic way to provide simple security. This after all is the protection applied to the additional c...

Re: Is my pi broken or i'm doing something very wrong?

From your description it seems unlikely that the Pi itself is faulty. The problem seems to be around trying to write new files to the SD card. Try running the command df and see if it shows there is spare space on the root file system. If the root file system is showing as full that would explain th...

Sounds as if you upgraded the copy of Raspbian on the SD card and then failed to copy the upgraded Raspbian to the USB drive? Alternatively if you had run step 2 while running with root on the USB stick then it would have upgraded the Boot related files in the boot partition on the SD card and then ...

Re: Free ram [solved]

What I find quite interesting in this thread is that nobody has mentioned that the amount of RAM that is allocated to the GPU (and thus not available to user programs) is variable and user configurable. Whether this is relevant to the question the OP was seeking an answer to is not at all clear.

It sounds like you have a generic Linux version for Intel based systems. You will need a version that is specifically built for the ARM processor on the Pi (assuming one even exists).

Could you be more specific about how you mounted the card and found /etc/rc.local? I think I mounted the card but can't find /etc/rc.local
If you have mounted the card, then the location will be of the form /<mountpoint>/etc/rc.local where <mountpoint> is where the card is mounted.

Thanks, but you still need a SD card, and it said something about once you change it to boot from a USB device, you can't change it. I want it to be like if I was swapping SD cards, when you just power it off, take out the SD card, put a different one in and power it back up. But in this case, inst...

As far as I know, omxplayer is the only way to get hardware accelerated Video that uses the GPU and codecs.

VLC does not use hardware acceleration (I.e. the codec via the GPU). You should instead try omxplayer if you want hardware acceleration of video playback.

Re: PI3 not operate

Also, the SD card must be in FAT32 format (and not exFAT). You may have to install a 3rd party tool to do this on a 64GB card as Windows will only allow exFAT for cards over 32GB.

you cannot using the standard OS level format. However there are third party utilities that CAN do this. It should be easy enough to find one appropriate to your system using Google.
