Sitara Linux kernel sources

David Cemin
Intellectual 400 points

Im going to be developing on the kernel for AM335 and AM572x. 

Currently I have 3 options (or maybe more)

  1. Get the kernel directly from kernel.org and develop from there
  2. get the kernel from git://git.ti.com/processor-sdk/processor-sdk-linux.git
  3. get the kernel from git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git

I have some questions and it would be really good if you could answer them all separately:

  1. How does TI repos differ from Linux kernel mainline ? (i.e. how often do you guys pull (or push) from (to) there? 
  2. what is the difference between the processor-sdk and ti-linux-kernel repos ? 
  3. Which branch on the repos mentioned above is the stable branch and which one do you suggest a new development start from (assuming no kernel constraints) ? 

Thank you 

best regards, 

David

    Hi David,

    First of all, I suggest you start developing on the already released SDKs:
    AM335x SDK:
    www.ti.com/.../PROCESSOR-SDK-AM335X
    AM57x SDK:
    www.ti.com/.../PROCESSOR-SDK-AM57X

    The repositories you point will work as well, but they may contain some work in progress. So we always recommend using the released SDKs.

    Now to answer your questions:
    How does TI repos differ from Linux kernel mainline ? (i.e. how often do you guys pull (or push) from (to) there?

    Every time a new SDK is scheduled/released. I don't have a roadmap on TI releases.

    what is the difference between the processor-sdk and ti-linux-kernel repos ?

    The linux-kernel repos are older kernels for older ti devices. Processors-SDK support Sitara, Vayu and Keystone devices.

    Which branch on the repos mentioned above is the stable branch and which one do you suggest a new development start from (assuming no kernel constraints) ?

    As I said, the stable releases are the official SDK releases. In git.ti.com there may be some ongoing work. However, if you decide you'd go with the sources from git.ti.com, I think it would be best to checkout the 4.4.y branches.

    Best Regards,
