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.
