General discussion • CM5 USB Boot Clarification — USB-C vs USB-A Pendrive Boot Support

Hi everyone,

I am using Raspberry Pi Compute Module 5 (CM5) with the official CM5 IO board and would like to clarify USB boot behavior.

I currently use the USB-C port with nRPIBOOT / EMMC-DISABLE jumper and rpiboot for flashing eMMC, which works correctly.

Now I want to understand normal USB boot using a bootable pendrive.

My questions:

1. Is normal USB boot from a bootable pendrive possible using the USB-C interface on the CM5 IO board?

2. Is USB boot from a bootable pendrive supported only through the USB-A host ports on the CM5 IO board?
