help customizing linux kernels

[PPoob]

i have troubles following the official intel documentation on building a custom image from : http://www.intel.com/content/dam/support/us/en/documents/edison/sb/edisonbsp_ug_331188007.pdf http://www.intel.com/content/dam/support/us/en/documents/edison/sb/edisonbsp_ug_331188007.pdf , as i feel that the explanation is no longer valid. as there is no edison-src.tgz available in the in the provided link to the edison software download page"https://software.intel.com/iot/hardware/edison/downloads IoT - Intel® Edison Board Download | Intel® Developer Zone". Furthermore i have tried using the available files from the software download page like the "https://downloadmirror.intel.com/25871/eng/iot-devkit-prof-dev-image-edison-20160315.zip Release 3.0 Yocto* complete image" but it dont even have any of the relevant files according to the intel documentation to compile the build, and the "http://iotdk.intel.com/repos/3.0/sources/i586-poky-linux/edison-image-1.0-r0/edison-image-1.0-r0-pat... Sources – Linux Source Files" page in it's self is no longer valid. so how to now i cant even custom build the kernel to enable PPP in this documentation : https://software.intel.com/en-us/articles/connect-a-gprs-modem-to-intel-edison IoT - Connect a GPRS modem to Intel® Edison | Intel® Developer Zone. Please help

You can check my tutorial on building from the sources: http://hobby.farit.ru/building-yocto-linux-for-intel-edison/ http://hobby.farit.ru/building-yocto-linux-for-intel-edison/

The sources for Yocto 3.0 are broken.

You can get the older version 2.1 from here: https://downloadcenter.intel.com/download/24910/Intel-Edison-Software-Release-2-1 Download Intel Edison Software Release 2.1

Look for the file edison-src-ww18-15.tgzhttps://downloadcenter.intel.com/downloads/eula/24910/Intel-Edison-Software-Release-2-1?httpDown=htt... Intel Edison Software Release 2.1

Thanks Vincenze !!

I am currently following your tutorial.

However right after the "Bitbake edison-image" i am reciving this problem:

"

Otherwise you should retry the download and/or check with upstream to determine if the file has become corrupted or otherwise unexpectedly modified.

Which i am guessing because the link to "ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.bz2 ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.bz2" is broken. How do I fix this ?

Thanks

The link is not broken. I can download the file.

[PPoob]

oh okay so is there any reason why I'm getting this error multiple times? And how do I overcome this issue

Thanks

Were you able to successfully complete Vincenze's guide and download ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.bz2 ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.bz2 ?

yes i am able to follow Vincenze's superb tutorial, and more importantly he provided a link to a mirror site to download the src file. Ontop of that i am also able to solve the problem i had regarding my later post, downloading ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.bz2 ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.bz2, this problem was simply due to my college firewall, and web restrictions. after i got over this i could download ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.bz2 ftp://ftp.gnu.org/gnu/gcc/gcc-4.8.2/gcc-4.8.2.tar.bz2.

Thanks alot guys, for everyone who helped in this forum,

Hi,

The "Sources-Linux Source Files" is currently down. This problem has been reported and we're working to fix it. I'll post back in this thread once the source files are available for download.Thank you for your patience.Sergio
