Don -
I can relate. That is why, once I figured out that I could simply
replace the
kernel and the modules on a working SD card (made by someone other
great person THANK YOU again), I was able to get out of the business of
making partitions and dealing with initrd/initramfs altogether. So
the answer
is, I don't know what my kernel command line is because I haven't
reached
the development step of customizing it yet. You should have exactly
FIVE
steps:
1. Create and verify bootable 2GB copy of that 512MB 2.6.29 dd image.
2. Download/Patch kernel source, edit top-level kernel Makefile to
point CROSS_COMPILE at your toolchain
3. Build kernel 'make ts72xx_def', 'make' and 'make
modules_install' (syntax below)
4. Insert 2GB SD card into reader and dd kernel to partition two
5. cp modules directory to partition four, replacing the prior
modules dir, unmount, remove card
That's it, nothing else.
