Hi Anthony,

Hi Anthony,
Which version of GCC do you have with Centos 5 (the output from gcc -v)?
I think this could be a bug, and the argument passed should be &(td[i]),
not td[i]. Try changing the source and see if it works. I'm not sure why
it gets through other compilers!

My application note uses Or1ksim 0.2.0, not 0.2.0rc2 (which was the
earlier release candidate 2). They are 2 months apart, so I imagine
there are bugs fixed in that time.

HTH,

Jeremy

Hi, Jeremy

The 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
Segmentation fault
