[gem5-users] Re: 4-core ARM with fs.py and fs_bigLITTLE.py

Hey,
Thanks! Yes, the configuration is the same. Now, with the compiled
bootloader it boots up with 4 cores.

Hi Majid,

Out of curiosity, are you sure the configuration is the same? Could you try to 
rebuild the bootloader in system/arm/bootloader/arm64 and make sure the config 
script is pointing to it?
(Either with M5_PATH or by using the --bootloader option)

Please let me know if this works

Kind Regards

Giacomo
