| NOTE: Cut-down firmware (`start*cd.elf` and `fixup*cd.dat`) cannot be selected this way - the system will fail to boot. The only way to enable the cut-down firmware is to specify `gpu_mem=16`. The cut-down firmware removes support for codecs, 3D and debug logging as well as limiting the initial early-boot framebuffer to 1080p @16bpp - although KMS can replace this with up to 32bpp 4K framebuffer(s) at a later stage as with any firmware. | ||

This should refer to Pi4 / Pi5 family because it applies to all devices including CM4.

In this sentence, I think "firmware" is referring to start.elf / start4.elf, which is still a separate file for the Pi4 family?

Yes, Pi4 family use start4.elf by default and Pi5 family is self-contained or perhaps more precise the BCM2712 bootrom family because that's the significant thing rather than the board design.

Yeah, it's always hard to get the balance right in technical documentation like this, but I'm happy to bow to @katshann-raspberry and @JeuneseRPi 's best judgement.

It seems like what this note wants to emphasise is the self-contained nature of the BCM2712 family firmware. I'm unclear as to why, though. What does the information in this note change about what the customer would choose or do after reading it?

This appears at https://www.raspberrypi.com/documentation/computers/config_txt.html#start_file-fixup_file so perhaps the NOTE is trying to explain that the BCM2712 (i.e. Pi5 family) doesn't use the start_file and fixup_file options? And yes, perhaps that could/should be made clearer 🙂

Thanks for the info on this one, folks. I'll pick up improving this note as a separate action for next week.

As a nit-pick, there should be no "The" at the beginning of the sentence.

In this case I believe it's talking about "The firmware..." - so perhaps the sentence should be rearranged to:
"The firmware for Raspberry Pi 5, 500, 500+, and Compute Module 5 is self-contained in the bootloader EEPROM." ?

You are correct. Forgive me. It's my first day back. I'll come up with a new excuse for mistakes I make tomorrow. ;-)
