Linux kernel .config for OMAP-L138 LCDK

Other Parts Discussed in Thread: DA8XX, OMAPL138

I'll be adding some devices via the expansion headers for the LCDK. For those devices, I'll need to do some driver development. But first, I want to build the linux kernel and verify it matches what was shipped.

The OMAP_L138 LCDK Linux Software Developer's Guide suggests:

... make da8xx_omapl_defconfig

... make menuconfig

...  Then change the configuration to match the board. However there is no hint on which of the >1000 options need to be changed.

Just trying the da8xx_omapl_defconfig options yields a kernel that won't run on this board. No surprise, since this isn't a da8xx!

Could you provide the .config file showing the options used when building the kernel shipped with the OMAP_L138 LCDK?

    Dave,

    Are you using this sdk ti-sdk-omapl138-lcdk-01.00.00?

    If so try omapl138_lcdk_defconfig

    LT,

    I did try omapl138_lcdk_defconfig. It doesn't work. In fact, the kernel would not even compile. Nor was it recommended by the TI documentation.

    However TI did respond on Thursday with a solution. Odd that it didn't get posted here, but their solution worked well:

    • The config file used to build the kernel can be extracted in run time by copying the file /proc/config.gz on the target to your host machine. If you are mounting the file system as NFS, just copy the file to /home/root.

    Using that config.gz file I was successful building a kernel that matches the kernel shipped with the LCDK.
