Could you build this?
No Porting the XNU kernel to a specific portable music player means kernel patches, device drivers, and a bootloader for undocumented hardware, which requires deep OS and embedded expertise.
What it would actually take: This needs low-level work: reverse engineering the JM21's SoC, boot ROM, and peripherals, writing a bootloader that loads XNU, and implementing drivers for display, audio, storage, and input. It calls for experienced kernel and embedded engineers plus hardware debugging tools such as JTAG or serial consoles and the device itself.
