Original question:

AM3352: CPSW timeout error

AM3352: CPSW driver migration

Antonio Santagiuliana

Part Number: AM3352

Hello 

We are using linux-kernel stable 4.9 ( 4.9.216 ) for AM335x.

I have now found we'd need CPSW driver version that is in ti-linux-kernel-4.9.y instead.

How do you suggest to proceed ? 

Should I be able to import the CPSW driver from there to linux stable kernel 4.9.216 and, if so, is there a patch for this ? I could not find it.

Or is it better to migrate completely to ti-linux-kernel 4.9.y ?

In this latter case, do you update ti-linux-kernel periodically producing revisions to 4.9.y Kernel ( like ti-linux-kernel-216 ) ?

thank you

    Hi,

    Officially TI recommends using the kernel in the latest SDK.  TI does not maintain patch sets to upgrade drivers between various releases.

    The option you suggested of migrating to the ti-linux-kernel 4.9.y is probably the next best option other than if possible upgrading to the latest TI SDK.  TI runs an auto-merge against the LTS tree but does not extensively test this kernel beyond verifying a boot test. So there is risk something may break when switching to this TI kernel. The latest tag on the 4.9.y tree, if I am reading it correctly is a kernel version of 4.9.220.

    Please note this kernel 3 years old and is out of the support window that TI provides.

    Best Regards,

    Schuyler

    OK, thank you for the information.

    I will firstly try to import only that driver version from ti-linux-kernel-4.9.y to our current kernel-stable-4.9.y. 

    Then we'll consider upgrading the whole Kernel to a newer version later.

    thank you
