Hi guys,
I've received this board for exploring the possibility to develop real time applications.
In the box there is a SD card with Android 4.2.2 bootable, so my first question is: Is this board suitable for real time applications?
If yes, i haven't found anywhere info about the flow to follow to develop a linux real time application.
Have you got some hints or tutorial to follow these steps (INCLUDED TOOLS and IDE)? I mean, making a linux bootable card and developing an application targeting the linux platform.
Thank you very much
Regards
It's the same,
i'm using ubuntu 14.04 and i tryed both bash and dash shell.
I'm trying to bitabke <image>
but i've got this error:
I verified that if i specify the link in firefox without ";name=ssvb" i succeed in downloading file.
Instead i don't if I keep ";name=ssvb".
I also verified in the .bb file that it contains this line:
Iis there a way to avoid this error?
Hi
Andrea
You can mannualy download these files and put to download folder. also prepare .done file and build again.
Thanks,
Saurabh
HI Andrea
documentation is included in Linux Doc bundle (please look at attached part of it)
In general linux is not real time OS
http://bis-linux.com/files/EUF-ENT-T0866_BIS-Embedded_Linux_for_i.MX-Real-World_Projects.pdf
for i.MX6 Linux one can look at RT recipe like linux-imx-rt-3.10.31 on
meta-fsl-arm/recipes-kernel/linux at master · Freescale/meta-fsl-arm · GitHub
Best regards
igor

Hi Igor,
Thank you for the answer.
I followed the steps in "Yocto User Guide" and tried to build the image:
5.5 Building an image
The Yocto Project build uses the bitbake command. For example, bitbake <component> builds the named component.
Each component build has multiple tasks, such as fetching, configuration, compilation, packaging, and deploying to the target
rootfs. The bitbake image build gathers all the components required by the image and build in order of the dependency per
task. The first build is the toolchain along with the tools required for the components to build.
The following command is an example on how to build an image:
$ bitbake fsl-image-gui
When i run this command, after a few time, it outputs these error messages:
WARNING: Failed to fetch URL https://raw.githubusercontent.com/ssvb/cpuburn-arm/dd5c5ba58d2b0b23cfab4a286f9d3f5510000f20/cpuburn-..., attempting MIRRORS if available

I verified that if i specify the link in firefox without ";name=ssvb" i succeed in downloading file.
Instead i don't if I keep ";name=ssvb".
I also verified in the .bb file that it contains this line:
SRC_URI = "http://hardwarebug.org/files/burn.S;name=mru \
What if i modify this file and delete the ";name=ssvb"?Or is there another way to avoid this error?
