Dear sir,
I have a target board with a flash on it, and I??d
like to put ppcboot-0.6.2 into it by a writer. But
when I compile ppcboot-0.6.2 under the environment of
RedHat Linux 6.2 and with the help of ppc_8xx-gcc
which is a compiling utility included by CDK1.2, the
following problems appeared.
1. A file can not be complied, the error message is:
>/usr/local/src/ppcboot/ppcboot->0.6.2/include/ppc_asm.tmpl:232:
Error:Rest of line >ignored. First >ignored character
is ??\??.
>??
>??
>/usr/local/src/ppcboot/ppcboot->0.6.2/include/ppc_asm.tmpl:242:
Error:Rest of line >ignored. First >ignored character
is ??\??.
>/usr/local/src/ppcboot/ppcboot->0.6.2/include/ppc_asm.tmpl:243:
Error:Rest of line >ignored. First >ignored character
is ??\??.
These lines located in ppcboot-0.6.2/include/ppc_asm.
tmpl can be writed as follows:
>#define STD_EXCEPTION(n, label, hdlr) \
> . = n; \
>label: \
> EXCEPTION_PROLOG; \
> lwz r3,GOT(transfer_to_handler);\
> mtlr r3; \
> addi r3,r1,STACK_FRAME_OVERHEAD; \
> li r20,MSR_KERNEL; \
> rlwimi r20,r23,0,25,25; \
> blrl ; \
.>L_ ## label : \
> .long hdlr - _start + EXC_OFF_SYS_RESET;\
> .long int_return - _start + EXC_OFF_SYS_RESET
Can you give me a hint to explain what happened.
2. When I read the Makefile of ppcboot-0.6.2/ (i.e.
ppcboot-0.6.2/Makefile), I find 4 lines like this:
> subdirs:
> @for dir in $(SUBDIRS) ; do $(MAKE) -C $$dir ||
>exit 1 ; done
>depend dep:
> @for dir in $(SUBDIRS) ; do $(MAKE) -C >$$dir
.depend ; done
but I can not find the definition of ??MAKE?? in this
file or the other files included by this package. Can
you tell me what ??MAKE ?? is and where the definition
locates?
3. If you think that I use the wrong versions of
RedHat Linux, or that I use the wrong CDK , or that
the way I compile ppcboot-0.6.2 is absolutely stupid,
please don't hesitate giving me a message.
Thanks in advance.
Best Regards
Yours sincerely Xuelong Wang
