The linux object did not go very far on my custom board. As soon as it
itself then it hang silently. The last printout is "Now booting the kernel".
I am trying to understand why printk() did not print out even one character
function is called at very beginning of start_kernel(). I had the following
1. What does this statement mean in kernel/printk.c ?
2. How does the underneath driver of printk() is initialized? If printk() is
init_IRQ(). I assume it can only push characters out instead of accepting
like putc() or serial_putc() before uncompessing linux. But after intense
linux source code, I am still puzzled...
This is the boot log.
Starting at 0x800000...
