Hello, L4 hackers :-)
I want to change root device on L4 Linux instead of ramdisk.
Root device I want is like '/dev/mtdblock0' or
'/dev/mmcblk1p1' instead of 'rom/ramdisk-arm.rd'.
So, I've configured somethings in 'L4 Linux menuconfig',
additionally.
Somethings are as follows ..
==============================
<*> MMC/SD/SDIO card support --->
<*> The Extended 4 (ext4) filesystem
[*] Ext4 POSIX Access Control Lists
[*] Ext4 Security Labels
==============================
kernel command line : "rom/vmlinuz.arm console=ttyLv0
root=/dev/mtdblock0 rootwait rw "
==============================
But it is hangs at 'Waiting for root device /dev/mtdblock0...'.
I've heard that the solution of this is to pass-through the physical MMC device to L4Linux.
Please, tell me it's concrete ways or hints about what I must study for solving this.
I can't even guess what the solution mean.. please.
