You should check if your image file support "bash" or "sh". Just mount
your image in specific folder, find bash or sh in /bin then adapt your
script.

Dear all,
I am having a problem trying to run the second script file after
restoring from checkpoint.
I have used used hack_back_ckpt.rcS to create 1st checkpoint after
booting from Linux. Here is the command I have used to run the
checkpointing:
*./build/X86/gem5.opt ./configs/example/fs.py
--script=./configs/boot/hack_back_ckpt.rcS*
*

And here is the result after checkpointing:

To run the second script file, this was what I used:
*./build/X86/gem5.opt --debug-flags=FaultInjection
./configs/example/fs.py --cpu-clock=250MHz --caches -r 1
--script=./configs/boot/dijkstra.py*
The result is shown as below:

On the terminal, all it showed was:
Loading new script…
This is the content of the 2nd script file:
*#!/bin/bash*
*echo ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>"*
*echo "Running Dijkstra benchmark now"*
*/sbin/m5 dumpresetstats [100, 100000]*
*./dijkstra_1_FI input_dijkstra10.dat*
*echo "Finishing now...."*
*echo ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>"*
*/sbin/m5 exit*
Without running checkpointing, the entire program was able to
terminate and provide proper result. However, with checkpointing, it
seems to be stuck at trying to read a new script.
I am not sure if I have missed any steps in between. I followed
through the discussions about this issue – I didn’t connect my
terminal during the 1st checkpointing, I view the result by tracing
the terminal file. I didn’t make any changes to the hack_back_ckpt.rcS
file. I also tried after loading the checkpoint and leaving the
—script empty, I brought up the terminal to try and input the script
file but only Ctrl+C made a difference. Anything other than that
showed no difference. So, I am not sure where I have gone wrong.
Appreciate all the help and guidance please.
Thanks.
Regards,
Elena
