MMC rootfs was mounted read-write (otherwise how could I even save output to files on it?).
I was playing with the device while only /usr was moved to mmc. Performance in some applications that use a lot of memory (browser, maps) was awful. Reducing swappiness (/proc/sys/vm/swappiness) from 100 to the kernel default 60 helped a little (swap was also on mmc).

Does anyone know what the correct CONFIG_CMDLINE is to boot from the external mmc on the n900?
Here is the default
Here is what I have
I have the mmc and appropriate filesystems compiled into the kernel, but I always get a kernel panic.
Any help would be great
Thanks
Here is the default
Code:
CONFIG_CMDLINE="init=/sbin/preinit ubi.mtd=rootfs root=ubi0:rootfs rootfstype=ubifs rootflags=bulk_read,no_chk_data_crc rw console=ttyMTD,log console=tty0"
Code:
CONFIG_CMDLINE="root=/dev/mmcblk0p3 rw rootdelay=5 console=ttyMTD,log console=tty0"
Any help would be great
Thanks

try root=MMmm hexadecimal notation, I guess there isn't /dev/whatever parser in kernel for all devices. At least N8x0/770 kernel uses root=1f03 for third mtd partition, mmcblk0p3 could be b303 (major 179, minor 3)
also init=/sbin/init (or whatever you use) might be good just in case
and BTW, you can install bootmenu if you don't mind booting initial code from internal flash and pivot_root-ing to new root a bit later, no kernel changes needed then

So did anyone successfully did it? If so can you please post detailed steps to Boot from my 16gb MMC? I would like to partition mine as 8gb VFAT, 7 plus gb for ext2 and the rest for swap.
Thanks in advance.
Thanks in advance.

As you go on to other communities, remember to build them around politeness, respect, trust and humility. Be wary of poisonous people and deal with them before they end up killing your community.. Seen it happen to too many IRC channels, forums, open source projects.
