Need help figuring out why my powerpc elf file causing seg fault

[deepzero]

Works perfectly fine for me just following your steps.
I do not understand why you change segment_start though? And where does 0x000FFF4C come from?

I am attaching my tests, sw versions I used:

deep@zero:~/tmp/ppc$ powerpc-linux-gnu-gcc --version
powerpc-linux-gnu-gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

deep@zero:~/tmp/ppc$ qemu-ppc --version
qemu-ppc version 4.2.1 (Debian 1:4.2-3ubuntu6.16)

deep@zero:~/tmp/ppc$ powerpc-linux-gnu-ld --version
GNU ld (GNU Binutils for Ubuntu) 2.34
