[Gumstix-users] Kernel Panic after adding Tinyx, pxaregs, and configuring for LCD

[<tho...@be...>]

The first time I tried reflashing a new rootfs, things didn't go so well.  I never did find an app to check the crc on the linux (coLinux with Debian) before downloading, so I downloaded the rootfs three times to make sure I got the same CRC all three times.  On the third time (with the same CRC), I tried reflashing the file system.

The boot up load follows.  The build seemed to go OK, except LOTS of warning messages when building Tinyx.  

One thought, do I HAVE to pass the boot arguments after configuring the kernel for LCD support (I didn't) to avoid a kernel panic?  Any other ideas?  If not, I guess I'll try rebuilding without Tinyx but with LCD configuration.

Also, does it matter whether I configure for LCD support before or adding Tinyx?

Finally,  do I have to start from scratch, or are the makefiles smart enough to allow a "make clean" or something similar after removing the TARGETS+=TINYX from the top level makefile.

Thanks,

Dave Thomas
