Hi there,
Now we are using eCos to develop code for a custom
board with ARM7TDMI core. When we generate the
library file using eCos, we included kernel package
only.
We changed the target.ld file according to the memory
layout of our board and now we could download the code
and run prefectly.
But there is one thing I am not quite sure, before I
can
download the code into the board, I have to set up
several registers such as EBI_CSR0, EBI_CSRI( chip
select register) and SF_PMR( protect mode register)
to enable the access to the on chip and on board
memory.I think maybe there will be a way for me to set
up all these registers in the vectors.s file, I
checked the eCos file and find one file under the
directry
ecos\packages\hal\arm\arch\current\src\vectors.s
Can I modify this file to set up the above registers
and generate the library again(get vectors.o file) ?
If I can, how to modify?
Thanks so much!!.
kiki
get the vectors.s file?
