Subject: When I use ichache_enable or dcache_enable in uboot,it crash
Date: Thu, 7 Dec 2006 17:52:29 +0800 [thread overview]
Message-ID: <20061207095910.AD77667BB2@ozlabs.org> (raw)
Hi,
In the very begin of the uboot, the dcache is disable and the icache
is enable. The code runs in flash nomarlly. Then the uboot should jump to
ram and if I don't disable icache the uboot will crash. I can't enable the
dcache too. The more serious problem is that when I boot the linux kernel
,it will stop at init_mmu. I think it is the same reason. Please help me.
Thanks & Br,
Andy
