Hi,
I'm doing kernel porting to arm926 based FPGA board,very
minimal setup (uart + timer only)
I'm getting kernel panic after cramfs root file
system is mounted,I am expecting to enter login prompt after root file system
is mounted.
Below are the details
#define PLAT_PHYS_OFFSET
0x80000000 (with 128 MB SDRAM)
#define CONFIG_PAGE_OFFSET 0xc0000000
Physical memory : 128MB (0x80000000 to 88000000)
ZRELADDR = 0x80008000
PARAMS_PHYS = 0x80000100
INITRD_PHYS = 0x80800000
Kernel cmd line : mem=32M console=ttySAC0,115200
root=/dev/ram0 rootfstype=cramfs init=/linuxrc initrd=0x80800000,8M
user_debug=31
I am not using u-boot and doing all the required initializations through trace32 cmm script.
After compiling the kernel, when I load vmlinux(through trace32) at 0x80008000, the kernel runs upto mounting the filesystem(though there is some issue in mounting the filesystem).
But when I load zImage at the same address i.e 0x80008000, I am getting
Uncompressing Linux...
uncompression error
-- System halted
in the console.
I made sure that I am enabling the config options CONFIG_XZ_DEC (xz decompression support) through menuconfig.
I suspected on the cramfs memory location and then tried loading only zImage at 0x80008000.,even after this the result is same.
Please let me know where could be the issue.
