Hello Guys!
I am newbe to redboot and ecos.
I has IXDP425 board with installed VxWorks loader.
Now i should change VxWorks loader to RedBoot loader.
I successful build cross-compiler gcc/g++ and ecos latest version from
CVS for IXDP425.
Now i has redboot.bin image for RAM and can load it to IXDP425 via
serial port direct to RAM, but what
address on RAM image(redboot.bin) must be started?
eCos image are position dependant. It has to be loaded at the address
it expects to be loaded. You can then execute it by jumping to the
first instruction.
Take a look at the .ldi file in the hal includes/pkgconf for your
target.
