Earlier _stext has been in the 0xc0008xxx range, but now I see: c0004000 (A) swapper_pg_dir c0008000 (t) .head.text c0008000 (T) _text c0008000 (T) stext c000804c (t) __create_page_tables c0008100 (t) __turn_mmu_on_loc c000810c (t) __vet_atags c0100000 (t) .text c0100000 (T) __exception_text_start c0100000 (T) _stext c0100000 (T) asm_do_IRQ c0100004 (T) do_undefinstr c010022c (T) do_IPI c0100230 (T) do_DataAbort c01003d8 (T) do_PrefetchAbort c0100470 (T) gic_handle_irq Jan Jan Karlsson Senior Software Engineer MIB Sony Mobile Communications Tel: +46703062174 sonymobile.com -----Original Message----- From: crash-utility-bounces@xxxxxxxxxx [mailto:crash-utility-bounces@xxxxxxxxxx] On Behalf Of Dave Anderson Sent: tisdag den 27 augusti 2013 15:26 To: Discussion list for crash utility usage, maintenance and development Cc: Fransson, Per 2 Subject: Re: Problem with kvbase for ARM ----- Original Message ----- > > > Hi Dave > > > > I have problems with the line (in arm.c) > > machdep->kvbase = symbol_value("_stext") & 0xffff0000UL; > > In the latest kernels this does not give the correct value.

OK, that can be changed. Where are the new symbols located? All the older ARM kernels I have start like this: crash> sym -l c0004000 (A) swapper_pg_dir c0008000 (t) .init c0008000 (T) __init_begin c0008000 (T) _sinittext c0008000 (T) _stext c0008000 (T) stext c000804c (t) __create_page_tables c0008104 (t) __enable_mmu_loc c0008110 (t) __enable_mmu c0008140 (t) __turn_mmu_on c0008158 (t) __enable_mmu_end c0008158 (t) __vet_atags ...
