well

Then, if what you say is correct, We should do almost all of the job by han=
d, ... this is very difficult and time cosuming....

What is the role of xmake tcl script in generated linux bsp?=20

I renamed all of ML40x to ML403 in all of the files of the generated bsp, b=
ut still I encounter this error while compiling the kernel using xmake:

arch/ppc/platforms/4xx/virtex.c:20: error: array type has incomplete elemen=
t type
arch/ppc/platforms/4xx/virtex.c:60: error: field name not in record or unio=
n initializer
arch/ppc/platforms/4xx/virtex.c:60: error: (near initialization for 'core_o=
cp')
make[1]: *** [arch/ppc/platforms/4xx/virtex.o] Error 1
make: *** [arch/ppc/platforms/4xx] Error 2

any body knows the reason for this error message?
