Build `syz-execprog` on your host machine for arm32 with `make TARGETARCH=arm execprog` and copy to `~/syz-bin` onto the SD card. You may try building syz-execprog on the Raspberry Pi itself, but that worked poorly for me due to large memory consumption during the compilation process. 11. Make sure that ou can now execute syzkaller programs: ``` bash cat socket.log r0 = socket$inet_tcp(0x2, 0x1, 0x0) - sudo ./syz-bin/syz-execprog -executor ./syz-bin/syz-executor -threaded=0 -collide=0 -procs=1 -nocgroups -nonetdev -nonetreset -notun -debug socket.log + sudo ./syz-bin/syz-execprog -executor ./syz-bin/syz-executor -threaded=0 -collide=0 -procs=1 -enable='' -debug socket.log ``` 12.
