[ECOS] Adding PCI eth pro100 for testing new port to MPC8313 RDB

[ECOS] Adding PCI eth pro100 for testing new port to MPC8313 RDB

[Oscar Gueta]

Hello all,

     In order to fully test the new PCI HAL for
Freescale's MPC8313 RDB I added an Intel PCI ethernet
(pro100) to the source tree as follows under
packages/devs/eth/powerpc/rdb/i82559/current/cdl:

cdl_package CYGPKG_DEVS_ETH_RDB_I82559 {
    display       "RDB pci intel i82559 ethernet
driver"
    description   "Ethernet driver for RDB pci intel
i82559."

    parent        CYGPKG_IO_ETH_DRIVERS
    active_if     CYGPKG_IO_ETH_DRIVERS
    active_if     CYGPKG_HAL_POWERPC_RDB

    include_dir   cyg/io

    # FIXME: This really belongs in the INTEL_I82559
package
    cdl_interface
CYGINT_DEVS_ETH_INTEL_I82559_REQUIRED {
        display   "Intel i82559 ethernet driver
required"
    }

    define_proc {
        puts $::cdl_system_header "/***** ethernet
driver proc output start *****/"
        puts $::cdl_system_header "#define
CYGDAT_DEVS_ETH_INTEL_I82559_INL
<cyg/io/devs_eth_rdb_i82559.inl>"
        puts $::cdl_system_header "#define
CYGDAT_DEVS_ETH_INTEL_I82559_CFG
<pkgconf/devs_eth_rdb_i82559.h>"
        puts $::cdl_system_header "/*****  ethernet
driver proc output end  *****/"
    }

.....

   I also added a new target to ecos.db in order to
insert the pro100 driver as follows:

package CYGPKG_HAL_POWERPC_RDB {
        alias           { "FreeScale MPC83xxRDB"
hal_powerpc_rdb powerpc_rdb_hal }
        directory       hal/powerpc/rdb
        script          hal_powerpc_rdb.cdl
        hardware
        description "
            The RDB HAL package provides the support
needed to run
            eCos on a FreeScale MPC83xx RDB board."
}

target rdb_pr100 {
        alias           { "FreeScale MPC83xx RDB board
with pro100" }
        packages        { CYGPKG_HAL_POWERPC
                          CYGPKG_HAL_POWERPC_MPC831X
                          CYGPKG_HAL_POWERPC_RDB
                         
CYGPKG_IO_SERIAL_POWERPC_MPC831X
                          CYGPKG_IO_PCI
                          CYGPKG_IO_ETH_DRIVERS
                          CYGPKG_DEVS_ETH_INTEL_I82559
                          CYGPKG_DEVS_ETH_RDB_I82559

        }
        description "FreeScale MPC83xx RDB board with
pro100"
}


	I created a Redboot minimal configuration, and is
defined as follows:

cdl_configuration eCos {
    description "" ;
    hardware    rdb ;
    template    redboot ;
    package -hardware CYGPKG_HAL_POWERPC current ;
    package -hardware CYGPKG_HAL_POWERPC_MPC831X
current ;
    package -hardware CYGPKG_HAL_POWERPC_RDB current ;
    package -hardware
CYGPKG_DEVS_FLASH_POWERPC_RATTLER current ;
    package -hardware CYGPKG_DEVS_FLASH_AMD_AM29XXXXX
current ;
    package -hardware CYGPKG_IO_PCI current ;
    package -hardware CYGPKG_IO_ETH_DRIVERS current ;
    package -hardware CYGPKG_DEVS_ETH_INTEL_I82559
current;
    package -hardware CYGPKG_DEVS_ETH_RDB_I82559
current ;
    package -template CYGPKG_HAL current ;
    package -template CYGPKG_INFRA current ;
    package -template CYGPKG_REDBOOT current ;
    package -template CYGPKG_ISOINFRA current ;
    package -template CYGPKG_LIBC_STRING current ;
    package -template CYGPKG_CRC current ;
    package CYGPKG_NS_DNS current ;
    package CYGPKG_IO_FLASH current ;
};


      Without importing the RedBoot, everything
compiles OK. I can see the ethernet driver compiling.
The problem is when Redboot minimal configuration is
imported and tried to be compiled, there are pci
library routines unresolved:

	I am completely lost here as in cdl files and in ecm
file PCI is included (I am also positive that library
is compiling and working as far as I can test). Does
anybody have a clue how to fix this code without
making dirty changes in the ethernet driver source
code or makefiles to force the compilation?
        
        Thanks in advance.

[ECOS] SO many ecos problems in learning ecos and they has made me crazy....SOS....

[sean yang]

I just learned to use ecos to build a i386 redboot follwing the http://ecos.
sourceware.org/，and I am confused by what I got:

1. I downloaded the ecos via wget as the instruction of
http://ecos.sourceware.org/getstart.html: wget --passive-ftp
ftp://ecos.sourceware.org/pub/ecos/ecos-install.tcl and install 

It,the ecos has been installed with the directory structure such
as:ecos/ecos-2.0/packages/hal/i386/arch/ecos-2.0;

 2. Then,I got the snapshot via
http://www.ecoscentric.com/devzone/snapshots.shtml and reinstalled it ,this
time the directory structre is ok as normal mentioned:

ecos/packages/hal/i386/arch/current;

 3. Then,I use the snapshot version to build the i386 and arm tool
chains,and then the redboot for i386 with configtool.exe(Version
0607)----BTW,and I don’t know how to get the configuretool_v1.3.net for
MLT---there is a error for building which confusing me so long a time:

make[1]: *** [src/redboot_linux_exec.o.d] Error 1

make: *** [build] Error 2

 

4. from the make log,there are two errors which I don’t know why at all
because:

   1).EAX has been declared in i386_stub.h and this file will be included by
hal_syscall.c if CYGSEM_REDBOOT_BSP_SYSCALLS defined,and I am sure that the
MACRO CYGSEM_REDBOOT_BSP_SYSCALLS has been defined;

   2).the cyg/crc/crc.h:this file will be included in redboot.h,but I
couldn’t find this file in this directory,why?could anyone tell me ?

 

5.I want to rebuild the confiuretool with the latest snapshot version,and I
followed the http://www.ecoscentric.com/devzone/configtool.shtml

  But the $HOME can not be understood by cygwin bash ,why?

Thank u very much …..

It looks like you are missing the hardware support functions for PCI
on your architecture.

If you look at '.../packages/io/pci/current/src/pci.c', you'll see
these comments:

  // CYG_PCI_PRESENT only gets defined for targets that provide PCI HAL support.
  // See pci_hw.h for details.
  #ifdef CYG_PCI_PRESENT
     ... all the generic code is protected by this #ifdef

Look at how PCI is supported on other platforms.
