Hi All, As i was not able to do kgdb with ppc as target, i decided to try first with two x86 PCs. On the target system after uncompressing the kernel i could not see any statement like "Waiting for connection from remote gdb". I think this is to be done by gdbserver on the target. I compiled the gdbserver but don't know how to use it here along with the target kernel. Can anyone give some tips how to do it or if am missing something . I followed the docs - kgdb_docu_full-2.4.pdf and kgdbquickstart-2.4.pdf Host: x86, RHEL-2.6.9-34.EL Target Linux- 2.6.15.5 <http://2.6.16.2/> The kgdb version : linux-2.6.15.5-kgdb-2.4
Please let me know if any other details required. Thanks Sudheer On 11/28/06, Anumolu Sudheer <[EMAIL PROTECTED]> wrote:
Hello All I am in process of learning kgdb and facing some problem with gdbserver. I am not able to "configure and make" the gdbserver . Sorry fot the long mail. Did anyone tried to compile the KGDB with this powerpc-eabi ?? Please help me in solving this. Setup datails are below.. Host: x86, RHEL-2.6.9-34.EL Target Linux- 2.6.16.2 Target Processor: AMCC440SPe The kgdb version : linux-2.6.15.5-kgdb-2.4 GDB version gdb-6.4-kgdb-2.4.tar.bz2 CrossCompiler - powerpc-eabi I applied the patch to the kernel and cross compiled it.(modified to solve the compilation errors as is not supported readymade). I used the steps given in "http://www.kegel.com/linux/gdbserver.txt " to build the gdb. I compiled the gdb for host with following commands #ls gdb-6.4 gdb-6.4-kgdb-2.4.tar.bz2 #mkdir ppc440 #cd ppc440 #/bin/sh ../gdb-6.4/configure --target=powerpc-eabi --with-solib-absolute-prefix=/opt/ppc440 #make #cd .. For gdbserver, if i give the "--target=powerpc-eabi" to "configure" script, it says the target is not supported by gdbserver and if i give "--target=powerpc-linux", it doesnt show any error but its output doesn't look fine . But when i do make. i get many errors saying many files are not found. (Adding few required header files didnt help.) I cross compiled the gdbserver with following commands: [EMAIL PROTECTED] gdb]# mkdir cross-ppc440 [EMAIL PROTECTED] gdb]# ls cross-ppc440 gdb-6.4 gdb-6.4-kgdb-2.4.tar.bz2 ppc440 [EMAIL PROTECTED] gdb]# cd cross-ppc440/ [EMAIL PROTECTED] cross-ppc440]# [EMAIL PROTECTED] cross-ppc440]# export CC=/usr/local/powerpc-eabi/bin/ [EMAIL PROTECTED] cross-ppc440]# export CFLAGS="-mcpu=405 -D__PPC405__ -msim" [EMAIL PROTECTED] cross-ppc440]# export ac_cv_func_mmap_fixed_mapped=yes [EMAIL PROTECTED] cross-ppc440]# /bin/sh ../gdb-6.4/gdb/gdbserver/configure --target=powerpc-eabi --host=i386 configure: WARNING: If you wanted to set the --build type, don't use --host.
