Mohammad,
I didn't have much success copying the entire BSP into the kernel. Please
see my post titled "Linux w/ML403 PLB TEMAC". It is basically the tutorial
of how I got Linux working on an ML403 board.

Subject: Please help me with compiling the kernel for ML403
Security Level:? Internal
Hi
It is some thing more than 2 weeks that I'm trying to compile the kernel
for ML403.
Posted to questions here, but unfortunately, didn't get any answer from the
experts here.
I have tested every thing I knew ( with my limited knowledge ) and now, I
really need your help.
I'm using the following set of tools:
EDK 8.2.02, ( Latest )
ELDK 4.1 ( Latest )
-I want to compile the 2.6.20 kernel, downloaded from kernel.org
-As the first step, in EDK, I choose linux 2.6 in software platform
generation settings,
-I generate the BSP.
-In the generated BSP , I convert all of the 40x strings to 403, also I
change the name of xparameters_ml40x to xparameters_ml403
-I copy the 2.6.20 kernel /eldk/ppc_4xx/usr/src/linux , and set all of the
needed env variables for cross compile, and set the needed changes in the
linux Makefile. ( ARCH and
CROSS_COMPILE )
-I copy the entire BSP into the root of the linux kernel.
-I edit the linux/arch/ppc/Kconfig file, and add these lines into it:
config XILINX_OCP
bool "Xilinx OCP"
default y
config XILINX_TEMAC
bool "Xilinx TEMAC"
default y
config XILINX_SYSACE
bool "Xilinx System ACE"
default y
config XILINX_EDK
bool "Xilinx EDK Support"
default y
-In the linux folder I execute the cow.tcl script provided with the BSP
from EDK ( I execute tclsh cow.tcl )
-I make a symbolic link , for config.h file, ( I go to linux/include/linux
and then ln -s autoconf.h config.h )
-I begin the menuconfig and set all of the needed parameters
-Now, I begin the make process by simply typing : make
- I encounter the following error:
arch/ppc/platforms/4xx/virtex.c:20: error: array type has incomplete
element type
arch/ppc/platforms/4xx/virtex.c:60: error: field name not in record or
union initializer
arch/ppc/platforms/4xx/virtex.c:60: error: (near initialization for
'core_ocp')
make[1]: *** [arch/ppc/platforms/4xx/virtex.o] Error 1
make: *** [arch/ppc/platforms/4xx] Error 2
- I can prevent this error by commenting these lines of
/arch/ppc/platforms/4xx/virtex.c file:
/* Have OCP take care of the serial ports. */
struct ocp_def core_ocp[] = {
#ifdef XPAR_UARTNS550_0_BASEADDR
{ .vendor = OCP_VENDOR_XILINX,
.function = OCP_FUNC_16550,
.index = 0,
.paddr = XPAR_UARTNS550_0_BASEADDR,
.irq = XPAR_INTC_0_UARTNS550_0_VEC_ID,
.pm = OCP_CPM_NA
},
#ifdef XPAR_UARTNS550_1_BASEADDR
{ .vendor = OCP_VENDOR_XILINX,
.function = OCP_FUNC_16550,
.index = 1,
.paddr = XPAR_UARTNS550_1_BASEADDR,
.irq = XPAR_INTC_0_UARTNS550_1_VEC_ID,
.pm = OCP_CPM_NA
},
#ifdef XPAR_UARTNS550_2_BASEADDR
{ .vendor = OCP_VENDOR_XILINX,
.function = OCP_FUNC_16550,
.index = 2,
.paddr = XPAR_UARTNS550_2_BASEADDR,
.irq = XPAR_INTC_0_UARTNS550_2_VEC_ID,
.pm = OCP_CPM_NA
},
#ifdef XPAR_UARTNS550_3_BASEADDR
{ .vendor = OCP_VENDOR_XILINX,
.function = OCP_FUNC_16550,
.index = 3,
.paddr = XPAR_UARTNS550_3_BASEADDR,
.irq = XPAR_INTC_0_UARTNS550_3_VEC_ID,
.pm = OCP_CPM_NA
},
#ifdef XPAR_UARTNS550_4_BASEADDR
#error Edit this file to add more devices.
#endif /* 4 */
#endif /* 3 */
#endif /* 2 */
#endif /* 1 */
#endif /* 0 */
{ .vendor = OCP_VENDOR_INVALID
}
};
- Instead of the ebove lines, I just put one simple line: ( I use uart lite
and not the 16550 so there should be no problem commenting these lines? )
struct ocp_def * core_ocp;
- now, I begin the make process again, The make process goes ahead but
after a long time it generates another error:
GEN .version
CHK include/linux/compile.h
UPD include/linux/compile.h

LD init/built-in.o

make: *** [.tmp_vmlinux1] Error 1
- If I do not add the BSP files from EDK to my kernel and compile the
kernel for ML403, every thing will be completely OK. ( But I want TEMAC )
- when I look in the original virtex.c file, I see that it has defined
ppc_sys_platform_devices but when I look at the virtex.c generated by
Xilinx, I see that it has a completely different structure, it has no
definition of this variable. It is completely different from the original
virtex.c
- I have tested the same things above, with different versions of 2.6
kernel, such as, 2.6.17.1 and 26-xilinx-devel ( which I download from
montavista using git near two weeks ago ) , I also changed the version of
eldk to 4.0 and to 3.5 ( with 3.5 I could not compile the kernel at all )
Any idea, Any suggestion and any thing which can help even a litte, is
welcome,
I really do not know what to do more.
Thanks.
