hi everyone,
i have a problem while trying to port Redboot to my
target board with MPC852T as the target processor.
I have the following setting for target in ecos.db
target xyz {
alias{ "XYZ PPC852 board" xyz852 }
packages {CYGPKG_HAL_POWERPC
CYGPKG_HAL_POWERPC_MPC8xx
CYGPKG_HAL_POWERPC_XYZ
CYGPKG_HAL_QUICC
CYGPKG_IO_SERIAL_POWERPC_QUICC_SMC
}
and the following package in my hal_powerpc_xyz.cdl
file
cdl_package CYGPKG_HAL_POWERPC_XYZ {
display "XYZ PowerPC evaluation board"
parent CYGPKG_HAL_POWERPC
requires CYGPKG_HAL_POWERPC_MPC8xx
define_header hal_powerpc_xyz.h
include_dir cyg/hal
compile hal_diag.c hal_aux.c xyz.S
implements CYGINT_HAL_VIRTUAL_VECTOR_SUPPORT
implements CYGNUM_HAL_QUICC_SMC1
the problem that when i try to bring up redboot on my
board, the code hangs in the call to the
set_debug_comm function by hal_if_init.
if i comment out set_debug_comm calls in hal_if_init,
it hangs in the call to the function
hal_plf_comms_init
can anyone plz suggest where i could be going wrong .
regards,
jasmine
