I think you need to figure out why all those C files have gone missing...

The plot thickens!!!  :-)  Ok, so I just opened logo_linux_mono.pbm and I see the following at the top:

/*
 *  DO NOT EDIT THIS FILE!
 *
 *  It was automatically generated from drivers/video/logo/logo_linux_mono.pbm
 *
 *  Linux logo logo_linux_mono
 */

So it looks to me like it got generated as part of the build process.   So that said, perhaps you should go back to a "out of the box build" to see where it's being generated and hopefully that will be the missing piece in terms of the step you're missing.

OK... that did it. I did the full build and the .c files came back:

mike@mike-VirtualBox:~/tisdk7$ ls board-support/linux-3.12.10-ti2013.12.01/drivers/video/logo/
built-in.o                 logo_linux_mono.c        logo_sgi_clut224.ppm

logo_dec_clut224.ppm       logo.o                   logo_superh_vga16.ppm
logo_linux_clut224.c       logo_parisc_clut224.c    Makefile
logo_linux_clut224.o       logo_parisc_clut224.ppm  modules.builtin
logo_linux_clut224.ppm     logo_sgi_clut224.c       modules.order

Another "make linux_clean" again to verify and they were gone:

mike@mike-VirtualBox:~/tisdk7$ ls board-support/linux-3.12.10-ti2013.12.01/drivers/video/logo/
clut_vga16.ppm             logo_linux_mono.pbm      logo_sun_clut224.ppm
Kconfig                    logo_linux_vga16.ppm     logo_superh_clut224.ppm
logo_blackfin_clut224.ppm  logo_m32r_clut224.ppm    logo_superh_mono.pbm
logo_blackfin_vga16.ppm    logo_mac_clut224.ppm     logo_superh_vga16.ppm
logo.c                     logo_parisc_clut224.ppm  Makefile
logo_dec_clut224.ppm       logo_sgi_clut224.ppm
logo_linux_clut224.ppm     logo_spe_clut224.ppm

So clearly they're being auto generated/cleaned as you noted... I guess I need a pbm file as well as a ppm file. This was not mentioned in the tutorial I was following.

I've changed the logo before as outlined in the steps in this post.  That was for the 3.2 kernel in SDK 6.0, though, but I'm pretty sure it's still valid.

I thought about Josh's post a bit and dug through the Makefile and I see it now. The Makefile is looking for the _clut224 suffix on the file name in order to know it's a 224 color image. By renaming my image (and the assiocated code changes in logo.c/Makefile/linux_logo.h) I can now see my code successfully compile.

I also understand that Josh's changes could be so simple because he was replacing the default 224 color Tux logo with the new one by naming his logo: logo_linux_clut224.ppm (the same name as the previous logo)

My one sticking point now is that I can't seem to get my logo to show up instead of tux. The code compiles and makes sense, but still Tux remains. I thought it was because the "logo" variable from logo.c was getting overwritten so I went back to the defconfig and updated it:

CONFIG_LOGO=y
CONFIG_LOGO_EMERSON=y
#CONFIG_LOGO_LINUX_MONO is not set
#CONFIG_LOGO_LINUX_VGA16 is not set
#CONFIG_LOGO_LINUX_CLUT224 is not set

So everything was removed except for mine, but still Tux is showing up... I'm hacking through the code right now trying to figure out why I can't see my logo, but that's where I'm at in case anyone else has other ideas.
