SD card access

Hi.

I’m investigating SD card access in general, and I’m finding a lot of unexpected behaviour.

Is it the case that the SD is only intended for booting and not for general access?

I can load multiple blocks from LBA 1 ok, which is what you’d need for booting.

But I can’t load single blocks and I can’t load multiple blocks from an LBA other than 1.

Is this intended behaviour?

Thanks
