I am a student studying with the Raspberry Pi 4.

I would like to learn about the embedded boot process, and I want to disassemble the startup4.elf file, but I was unable to do so with objdump or the GCC disassemble tool.

I understand that it uses the ISA of the Videocore VII GPU, and I am wondering if there is an official disassemble tool for this.

Or is there another efficient disassemble tool available?

Thanks for your helps!

I have used tool ‘vc4asm’.

Downloaded and build, but there is an error message, “The system is: Linux – 6.6.30-v8+ – aarch64”.
