Subject: about s3c2442
Date: Thu, 10 Jan 2013 15:07:04 +0000	[thread overview]
Message-ID: <1974332.EjF16fPj1U@yiqingliang-pc> (raw)

Hello,
	I'm using barebox (based on mini2440) on my s3c2442 board,
1. flash barebox into nand: can't start normally, but can see early output on 
serial.
2. load it in sdram: can start normally into shell, and then I use it to boot 
kernel (also in sdram, also based on mini2440).
the kernel hang, no output.

after dig into it, I found something: add "mem=64M" into the kernel paramer, 
then the kernel can start.

BUT:
the barebox doesn't pass that paramert to kernel for mini2440,
why the mini2440 kernel can start normally?

how does the kernel on 2440 get the sdram size?

THANKS!
