This Linux kernel already has support for following boards 1. zylonite_pxa300 2. cm-x300 3. colibri-pxa300 4. littleton My doubt is that pxa300 based boards are using "0xa0000000" as DDRAM base and PHYS_OFFSET is also defined in "arch/arm/mach-pxa/include/mach/memory.h" as 0xa0000000. But in our board DDR is mapped in 0x80000000. Does it make any problem?. Because after mmu is turned ON, my board is hanging. "zreladdr-y := 0x80008000" is defined in "arch/arm/mach-pxa/Makefile.boot" file . my machine_desc is as follows .phys_io = 0x40000000, .io_pg_offst = (io_p2v(0x40000000) >> 18) & 0xfffc, .boot_params = 0x80000100, With Thanks J.Balakrishnan
