yocto meta-ti status for L138 (syslink)

Massimiliano Cialdi

hi,

trying the last meta-ti (git://git.yoctoproject.org/meta-ti) but it fails to build (for OMAP L-138) due to some patch missing (eg: https://e2e.ti.com/support/embedded/tirtos/f/355/p/451117/1623748#1623748).

I wonder if it was tested for L138.

Once applied all the patch I can build and load the syslink module, but it fails to run the examples.

best regards

Max

    Hi,
    Yes, we have not tested syslink examples with latest kernel version.
    We have tested for linux kernel 3.3.
    What is your syslink version ?

    I use syslink 2.21.01.05

    Ok, so meta-ti is not tested with L138, because meta-ti builds mainline kernel 3.14.43, and it seems that some patch aren't applied to syslink (eg: http://processors.wiki.ti.com/index.php/MCSDK_OMAPL138_User_Guide_Chapter_Exploring#Build_Syslink

    Anyway it seems that there isn't much work to do to make syslink works with more recent kernels (also 4.2). At least it seems to me

    best regards

    Hi mastupristi,

    Not sure about kernel 3.14.
    Only for Linux kernel 3.3, it is been tested. The recommended version is 3.3

    You can go-ahead and give it a try. It will be useful for community members too. we haven't tried yet.

    I did some tests:

    I cannot go further to this investigation, but maybe these infos are useful for somebody else in this community.

    Hi Mastupristi,
    Thanks for sharing your workaround.
    Surely it would help other community members as well.
