Hi Gelin,
Are you compiling gem5 in debug mode?
You can do that by using “debug” instead of “opt”:
$scons build/ARM/gem5.debug -j`nproc`
Kind Regards
Giacomo

Subject: [gem5-users] Re: Problem with checkpoint and restoration in gem5 se
mode
Hi, Giacomo.Thanks for your reply.
I am not familiar with gdb in se mode. So I try to use debug functions such as
curTick() and eventqDump(). But gdb tells me that there is no symbol about
eventqDump() and curTick. So I only use backtrace when the program aborted.
I am using the command as below:
gdb --args $GEM5_BIN --outdir=$OUTPUT_PATH $GEM5_PATH/configs/example/se.py \
--num-cpu 1 --cpu-clock 2.5GHz --cpu-type O3_ARM_v7a_3 \
--restore-with-cpu O3_ARM_v7a_3 -r 1 --checkpoint-dir \
"$CHECK_PATH" --caches --mem-type DDR3_2133_8x8 --mem-size 1GB \
-c "$TARGET_PATH" --options "$DATA_PATH"
the gdb output are as below:
(gdb) r
