Can't boot NetBSD from SDcard via UEFI on Raspberry Pi 5 (8GB D0) - sdmmc1: couldn’t enable card: 60

[Tim McIntosh <tmcintos%eskimo.com@localhost>]

Hello,

I recently purchased a Raspberry Pi 5 (8GB, D0 stepping) and have been trying to boot NetBSD on it via UEFI (following the instructions on the wiki <https://wiki.netbsd.org/ports/evbarm/raspberry_pi/>), but have had no luck.

I believe I’ve tried all of the following:

https://nycdn.netbsd.org/pub/NetBSD-daily/netbsd-11/latest/evbarm-aarch64/binary/gzimg/arm64.img.gz
https://nycdn.netbsd.org/pub/arm/HEAD/20260101113528Z/NetBSD-HEAD-aarch64-20260101113528Z-generic.img.gz

I’ve also tried fiddling with the UEFI settings, with no improvement.

In all cases, boot fails after these errors:

[4.3283271] sdmmc1: couldn’t send I/O OCR
[4.3383275] sdmmc1: couldn’t enable card: 60
[7.4883652] sdmmc1: couldn’t send I/O OCR
[7.4983656] sdmmc1: couldn't enable card: 60
[10.3984004] sdmmc0: couldn't enable card: 60

Is this a known issue?

I saw some previous discussion concerning a similar error recently <https://mail-index.netbsd.org/port-arm/2025/09/18/msg009409.html>, but I’m not sure if that’s related, as that fix would appear to be in at least the HEAD build that I tested.

The SD card is a new SanDisk Extreme PLUS microSDHC UHS-I 32GB <https://shop.sandisk.com/products/memory-cards/microsd-cards/sandisk-extreme-uhs-i-microsd?sku=SDSQXAF-032G-GN6MA>. I used the Raspberry Pi Imager app on macOS to write the NetBSD image, mounted the boot partition with diskutil, and then copied over the firmware from <https://github.com/NumberOneGit/rpi5-uefi/releases/download/v0.1/RPI5_D0.zip> to the boot partition as instructed before unmounting and attempting to boot from the card.

Thank you,

Tim McIntosh
