[U-Boot-Users] Linux Hangs After Uncompressing Kernel

i download a 6M Byte kernel(28M bytes uncompressed) to SDRAM(0x4000000), it hangs after uncompressing kernel.
when i use standalone downlod the kernel, i found the text section which offset is 8M bytes is not the same as the objdump file of the elf file. is there any limited size about kernel ? i used amcc ppc440 sequoia board

Seems definitely huge, what are you doing exactly ?

I have never seen such a big kernel image. I can't believe that it should be possible to configure such a huge kernel, even with all options enabled. You must be doing something wrong here.

Where did you get the linux kernel? What version are you using?
Best regards, Stefan

my kernel is really a huge kernel, i found in u-boot
/* * For booting Linux, the board info and command line data * have to be in the first 8 MB of memory, since this is * the maximum mapped by the Linux kernel during initialization. */ #define CFG_BOOTMAPSZ (8 << 20) /* Initial Memory map for Linux */
1. does 8MB is the maximum mapped by the Linux kernel during initialization?
2. does it mean i can change the kernel options or u-boot options to fix it?
