    <p>What loader do you use? What is the form of the "image"? U-boot image, raw one, vmlinux ELF file? I guess the last one judging by the existence of sections, etc. From ELF file you should load not sections but rather so called program headers. For example this is the OpenRISC linux kernel program headers listing (obtained using <code>readelf -l</code>):</p> <pre><code>Elf file type is EXEC (Executable file) Entry point 0xc0000000 There are 2 program headers, starting at offset 52 Program Headers: Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align LOAD 0x002000 0xc0000000 0x00000000 0x231728 0x232000 RWE 0x2000 LOAD 0x234000 0xc0232000 0x00232000 0x17c78c 0x18bfcc RWE 0x2000 Section to Segment mapping: Segment Sections... 00 .text .rodata __ksymtab __ksymtab_gpl __ksymtab_strings __param __modver 01 .data __ex_table .head.text .init.text .init.data .bss </code></pre> <p>See the difference between <code>VirtAddr</code> and <code>PhysAddr</code> (dropped <code>c</code> due to usual Linux kernel mapping). Naturally, the physical address should be used for loading.</p> <p>The reason kernel is using virtual addresses for symbols, sections etc is that during boot you quickly enter the moment when the MMU is initialized, the virtual addresses are then the only valid ones.</p> <p>And finally, about changing those addresses. Indeed, as pointed by Alexey, linker script is the key. You can find these in <code>arch/(your arch)/kernel/vmlinux.lds.S</code>. But the point is this is IMO not your problem, the problem lies probably in the loader or its options.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
