Flag format - `byuctf{0x000000}`
[start]
This executable was compiled on a Raspberry Pi, so it's a 32-bit ARM executable. PIE is also disabled on the executable, so the start address of the binary is known. It's normally 0x400000 for 64-bit AMD executables, but is 0x010000 for 32-bit ARM executables. Opening this binary in GDB will reveal the address.
Flag - byuctf{0x0103d0}
Compiled with gcc -o start start.c -no-pie on a Raspberry Pi, bullseye release.
