Subject: RE: [ECOS] Redboot :: __startup_stack
Date: Fri, 01 Jul 2005 12:37:00 -0000 [thread overview]
Message-ID: <C03A3C267DDF184EA523BBAB577BF92405B12C@blrexsr1.slti.sanyo.co.in> (raw)
Hi
I was able to get the redboot working by disabling the gdb stubs. (which
effectively makes initialize_stub not be called).
Now redboot prompt appears.. although some junk characters are taken as
input and the program seems to be in infinite loop.
But i am unable to understand what is that in the gdb stubs which is
making the redboot to crash. If you can throw some light on some of the
possibilities it would be great !!
Thanking you
harsha

SECTION_fixed_vectors (ram, 0x20000020, LMA_EQ_VMA)
Add an sram memory region and change this to 0x20 and the fixed
vectors will move.
