The version of QEMU in DECAF matters?
I want to use qemu in DECAF while using the firmadyne to run mips firmware, but the network doesn't work like this: Please press Enter to activate this console.

And I checked the version of QEMU used in DECAF is 1.0 while the QEMU downloading by apt-get is 2.11.1. So I want to ask how can we update the version of QEMU used in DECAF
It is nontrivial to upgrade QEMU in DECAF. We have another project that uses DECAF to fuzz IoT firmware. In this project, DECAF has been upgraded to use QEMU 2.0.

You can take a look.
Thanks, Heng

I appreciate this project, while I can't compile the DECAF_qemu_2.10 plugins once adding "--target-list=mipsel-softmmu,mips-softmmu,arm-softmmu --disable-werror", but I encounter some bugs when compile the whole project like this: " cannot convert ‘unsigned int*’ to ‘gva_t* "
