Hello all,
I am trying to port a working linux under development board to a board designed with similar features.
I use uboot, Linux 3.2.0-rc5 and jffs2 root filesystem (all these working on dev board).
My problem is that linux locks after displaying "Freeing unused kernel memory", so I checked source code, added printk(s) and found that it was kernel_execve() that locks when trying to call init.
I am not 100% sure my rootfs partition is well mounted, even if linux prints "VFS: Mounted root (jffs2 filesystem) on device 31:3." because I have write access and protection problems with uboot.
Anyone has experienced similar problems?
How can I be sure my rootfs is ok?
Can I read my root fs inside the kernel?
Regards
eric
