Is there any way to mount an SD card in a BeagleV Fire running `trixie`?

Yes, I see your predicament.

@RobertCNelson I am having trouble removing the sd_card_cs fix we spoke about a while back.

The BVF won’t get past mounting the rootfs partition without the hog:

[    2.519119] mpfs-generic-service mpfs-generic-service: Registered MPFS generic service - FOR DEVELOPMENT ONLY, DO NOT USE IN PRODUCTION
[    2.532515] mpfs-sys-controller syscontroller: Registered MPFS system controller

Could this be a 6.6 regression?
It makes no difference wether an SD card is in the receptacle or not…

I have tried both

fdt rm /soc/gpio@20120000/sd-card-cs-hog

and

fdt rm /soc/gpio@20120000/sd-card-cs-hog output-high
fdt set /soc/gpio@20120000/sd-card-cs-hog output_high

to do a quick poke; no difference.
