    What is the source of the Linux Kernel v2.6.14 for the DM355?

  • TI__Mastermind 37340 points

    The Linux Kernel that comes with our current DVSDK is based on 2.6.10 which may not have all the fetures of 2.6.14 kernel; I believe this is whay Brandon was asking where you got the Linux Kernel you are using.

    FYI, a future DVSDK will be based on MV Pro 5 with Linux kernel 2.6.18.  To my knowloedge we do not have any 2.6.14 DM355 Linux kernel, although applying patches to 2.6.10 may make it come pretty close, but figuring out which patches to apply is a challenge itself.  MontaVista provides patches thru their MV Zone web site, but access to this is limited to users who purchase a MV License.  You can purchase an MV License thru one of our DVSPB software bundles (http://focus.ti.com/docs/toolsw/folders/print/tmdsdvspba9.html), but then you will still have the homework of foguring out which patches, if any, will get you what you need.  I would recommend waiting for the next DVSDK release.
