- Subject: [ECOS] Why I can't exec the linux kernel
Hi all:
I have porting the redboot to coyote + ixp425 successfully. When i use "exec" command to run my linux-2.6.6 kernel, all things are ok.
However, When I ported the same redboot to my development board, which is like to coyote machine, i can't use "exec" command to run it. After I "load -r -b 0x30000 zImage" and typed the "exec" command, the system halted. There is nothing displayed.
I check the arch/arm/boot/Makefile, the ZTEXTADDR is 0. I think that "exec" will reload the zImage from 0x30000 to 0x0 and decompress it into 0xc0008000, then the kernel image will start to run.
What's wrong with my problem? Please give me some suggestions. Thanks!
daniel
