uClinux without Flash (again)

i have mmc/sd sockets on some of my boards.

and i am going to try out.

the nios spi is not good for mmc/sd.

i am using pio ports instead.

i think using "root=/dev/mmc" is not a good idea.

after the system boot, the mmc/sd card may be unplug, and another be plug in later.

so i am going to keep initramfs as root fs.

the devfs was obsolete, and will be replaced by udev.

i am going to mknod mmc with fixed device number.

i will also check mmc driver from newer kernel.

I&#39;m moving away from SD/MMC, because it doesn&#39;t seem too supported - on a new version of the board, I will use CF instead, and no CFI since I think it&#39;s a waste to have on-board flash. If I can get this initramfs working, then I can just boot from RAM and then mount CF after init.

I will try this with windows, but if not, then linux - I am using slackware, so I am only at GCC 3.3.4 - I need to understand the toolchain better first.

If I remove that dos2unix line altogether, this is what I get:

if I jsut comment it out with a &#39;#&#39; in front of it, I still get the truncated file warning, and the build fails with:

Have you tried doing this in windows yourself?

Adding the debug statement you told me shows this:

unpack_to_rootfs 118ed98+bd813 check 0

Out of curiosity, are those linux binaries that comes with the NIOS II distribution any good? Aren&#39;t those part of the toolchain? nios2-elf-gcc for xample..
