Hi,
Where is in ecos tree files, where redboot initialization code to be
done(before cyg_start call)?
I need insert some debug info.
normally execution begins at the processors reset vector. For the
i386-architecture you can find the implementation of this vector service
routine in 'packages/hal/i386/arch/current/src/vectors.s', the reset vector
service routine should be called '_start' (for i386). For other
architectures you should find the implementation under
'packages/hal/<your_arch>/arch/current/vectors.s' the name of the service
routine may differ.
Ciao, Fabian
I has IXDP425 board with IXP420 CPU.
But in
/opt/ecos/ecos-2.0/packages/hal/arm/xscale/ixp425/current/src/
and
/opt/ecos/ecos-2.0/packages/hal/arm/xscale/ixdp425/current/src/
no such file vectors.s or something like that.
