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:

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?
yes, it is. USB or NVME (via hat) storage is best for root anway.
