Subject: [openrisc] Updated OpenRISC toolchain instructions
Hi, JeremyThe system is Centos 5.
GDB enviorment:
according to AP your provided, I have download a pure GDB5.3 from gnu
ftp server, and patch from embecom, but it give out some errors while
I did as follows
1059 tar -zxvf gdb-5.3.tar.gz
1060 cd gdb-5.3
1061 ls
1062 bzcat -dc ../embecosm-or32-gdb-5.3-patch.bz2 | patch -p1
1063 cd ..
1064 ls
1065 mkdir b-gdb
1066 cd b-gdb
1067 ../gdb-5.3/configure --target=or32-uclinux
1068 make all
../../gdb-5.3/gdb/or1k-tdep.c: In function ‘or1k_skip_prologue’:
../../gdb-5.3/gdb/or1k-tdep.c:771: warning: ‘saved_reg_frame_offset’
may be used uninitialized in this function
../../gdb-5.3/gdb/or1k-tdep.c: In function ‘htrace_print_command’:
../../gdb-5.3/gdb/or1k-tdep.c:2396: error: incompatible type for
argument 2 of ‘print_data_struct’
make[1]: *** [or1k-tdep.o] Error 1
make[1]: Leaving directory `/root/or1k/b-gdb/gdb'
make: *** [all-gdb] Error 2
Actually, I have no GDB yet.
About the simulator, accutually, I am now used the one that provided
by MOF
That is or1ksim-0.2.0rc2
Can you tell me what's the difference between the 2 verison simulator
About the section uart, when I use xterm in the channel
it will report:
Resetting PIC.
Starting at 0x00000000
