Hi, Jon
Now, I have download bluemug's kernel image + initrd to EDB7211 DRAM with Shoehorn3.1.
Then system run with those message:
last message:
VFS: Mounted root (ext2 filesystem).
Free init Memory 68k
then system wait input.
When I press keyboard, system respond some message. For example:
'k' ---> SAK
'b' ---> restart
'o' ---> power off
etc.
I found this code in "drivers/char/sysrq.c".System can't run shell.
But I want to run shell and some script after kernel init, how can I do?
And where can I find some detail documents about "run shell and edit script"? Thanks.
Best regard.
Eric
