Enter STEP to go to High-level module. It seems your debugger loads only the boot loader code, but neither the kernel nor the initrd. > This is the section map through the command 'objdump -h zvmlinux.initrd' > > -------------------- > zvmlinux.initrd: file format elf32-big > > Sections: > Idx Name Size VMA LMA File off Algn > 0 .text 000046e4 00400000 00400000 00010000 2**2 > CONTENTS, ALLOC, LOAD, READONLY, CODE > 1 .rodata 000004a0 004046f0 004046f0 000146f0 2**4 > CONTENTS, ALLOC, LOAD, READONLY, DATA > 2 .data 0000030c 00405000 00405000 00015000 2**2 > CONTENTS, ALLOC, LOAD, DATA > 3 .bss 000051f0 00406000 00406000 00016000 2**2 > ALLOC > 4 .image 00064605 00000000 00000000 00016000 2**0 > CONTENTS, READONLY > 5 .initrd 00201d19 00000000 00000000 0007a605 2**0 > CONTENTS, READONLY > > Why weren't .image, .initrd section loaded? Because they aren't elf format file? Most probably because your debugger loads only such sections that have the "LOAD" flag set. > What can I do? I haven't any idea. There are several solutions; for instance, use objcopy to set the "LOAD" flag on the '.image' and '.initrd' sections, too.
