Hello all,
I am porting Linux and MicroWindow to EPD7212 demo board that provided by Cirrus Logic. I have download Linux kernel patch from www.maverickaudio.com.
And kernel version is 2.2.1. I also download arm toolchain. I have succeed to compile kernel with initrd and download image to flash rom. Kernel have run correct.
Now, I have copy some libs in /lib in initrd. Library and symbolic is:
ld.so.1 --> ld-2.1.2.so
libc.so.6 --> libc-2.1.2.so
libdl.so --> libdl.so.2
libdl.so.2 --> libdl-2.1.2.so
But when I compile a "hello world" sample code with compile param "arm-linux-gcc hello.c -o hello", then copy this file to initrd. When I run command "./hello" some error occur.
"kernel panic: Unknown data abort code 4194304 [pc=40002a10, *pc=e1dc30be] LR=40002a10"
Then system hung up. Why???
Anybody can help me? Thanks.
Eric
