Refer to the code in > arch/ppc/mbxboot/misc.c Yes, I use the mpc8xx.2.2.13.tgz to compile the kernel "zImage". Do you mean that when I download the kernel "zImage" to RAM address 0x100000 on our own board (but not mbxboard) , and jump to 0x100000, It will automatically run the uncompress program to copy and decompress the kernel to 0x200000, then jump to 0x200000, the decompressed kernel will boot, right ? > > > I'm not the expert, Dan is, but he's been teaching me. > > jeff > ----- Original Message ----- > From: "dony" <dony.he at huawei.com.cn> > To: "Raphael Bossek" <raphael.bossek at solutions4linux.de>; "Brendan Simon" > <bsimon at ctam.com.au>; "Dan Malek" <dan at netx4.com>; "linuxppc-embed" > <linuxppc-embedded at lists.linuxppc.org> > Sent: Thursday, December 30, 1999 9:29 PM > Subject: Please help me... > > > > > Hi, > > Now I am trying to embed linux onto our MPC860-based board.
