The locking issue I think I posted a while a ago. I cannot say which kernel last worked there; that was likely from 2024. I found an arm64 MMCCAM kernel from around 2025-03-18/26 which works on the LS1088. Seems the last commit from main on that branch was 12bff22669cf . # camcontrol devlist -v scbus0 on sdhci_slot0 bus 0: <SDHC FD4Q5 3.0 SN 7D9E55CA MFG 05/2022 > at scbus0 target 0 lun 0 (pass0,sdda0) ... In either case the nvme does work by the way. It's just mmccam it seems which does not. -- Bjoern A. Zeeb r15:7home | help
