At http://sources.redhat.com/ecos/docs-latest/redboot/excaliburarm9.html say that romram mode runs redboot from ram with redboot in flash. I supossed that redboot is stored in flash memory and then it is copied from flash to ram. But when i desassemble the file i get the code is mapped on ram (0x8000): redboot.elf: file format elf32-littlearm Disassembly of section .rom_vectors: 00008000 <__exception_handlers>: 8000: ea00000e b 8040 <_stext> 8004: e59ff018 ldr pc, [pc, #24] ; 8024 <.undefined_instruction> 8008: e59ff018 ldr pc, [pc, #24] ; 8028 <.software_interrupt> 800c: e59ff018 ldr pc, [pc, #24] ; 802c <.abort_prefetch> 8010: e59ff018 ldr pc, [pc, #24] ; 8030 <.abort_data> 8014: 00000000 andeq r0, r0, r0 8018: e59ff018 ldr pc, [pc, #24] ; 8038 <.IRQ> 801c: e59ff018 ldr pc, [pc, #24] ; 803c <.FIQ> 00008020 : 8020: 00000040 andeq r0, r0, r0, asr #32 00008024 <.undefined_instruction>: 8024: 00008494 muleq r0, r4, r4 00008028 <.software_interrupt>: 8028: 000084b8 streqh r8, [r0], -r8 etc.... Maybe i don`t understand this mode at all. thanks. -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
