Thanks for the screenshot. There are two easy ways to trace this down.

1. Start rockbox as root. May be it's a permission issue.
The binary is located in /opt/rockbox/bin/rockbox.

2. Install strace and capture the rockbox output.
Example command:

Code:

strace /opt/rockbox/bin/rockbox 2>&1 |grep -v clock_gettime |grep -v futex

When I enter into /home, the output looks like this:

Code:

open("/home", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY) = 14
fstat64(14, {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
