Booting 500 GB SSD on FreeBSD-ARM64-14.0 January 27, 2022  snapshot  https://freebsd.org/where


I used Manjaro Linux and the application gparted to manually create several Partitions on the SSD disk drive.  [ USB 3.0 external metal case Hornet Tek ASMT 2235] 


Install FreeBSD 14.0 Snapshot RPI3 to USB 3.0 500GB SSD in an external HornetTek metal case Drive enclosure:

dd if=./FreeBSD-ARM64-RPI3.img of=/dev/da1p4  bs=1m conv=notrunc  status=progress

Look at the location difference between  a single USB Flash drive stick  /dev/da1   and the SDD /dev/da1p4  into a slice (linux primary partition ) versus if  I used /dev/da1 for the whole disk.  So does the U-Boot have logic to do both to boot from a SSD (1.) boot whole drive and then 2.0 boot a single Slice that has 2 partitions 1.) MSDOS FAT32 2.) BSD with a label. )

So I am missing  efibootmrg on  aarch64 FreeBSD 14.0 snapshot to set the "boot order".  Missing ubootefi.var  variables?

So  look at more details here at https://ghostbsd-arm64.blogspot.com {not like a web page with text files, yet I can display pictures I took with a camera here }.AR  I have not made the post "Booting 500 GB SSD on FreeBSD-ARM64-14.0 January 27, 2022  snapshot".  yet.

Simply,  I am asking:

 1.)  Can U-BOOT and UEFI handle booting from an image installed to a  slice or does it have to be an image installed to a full disk?  How do you point the UEFI loader to select this one slice?  Which tools accomplish that?  Are those tools already loaded inside the snapshot image downloaded from FreeBSD.org/where ??  I don't have ethernet access here and the internal wifi device does not have a working device driver for the Broadcom wifi.

 2.)  Is there a method, to boot Rod Smiths rEFInd aaarch64 boot manager to allow FreeBSD 14 ARM64, POP!_OS ARM64, Manjaro Linux ARM64, Raspup 8.2.1 (ARM32) from the same disk?   Is there a UEFI work around using EFIBOOTMGR, EFI commands: printenv , setenv, run bootcmd  ??

URLS to read are good resource, that I would read.

pss.  Hard when you are starting out, to know what commands to issue in which sequence for the desired effect, unless you follow a pattern worked out by someone else. I learn from creating pictures
in my minds eye,  or looking at pictures to establish a visual map of how these commands and piece and  data fit all together.  With out a picture map, I am left confused about the relationship of the pieces.
 If I run eifbootmgr on my FreeBSD developer machine with the SSD plugged in.  It sees the other devices and proceeds to setup the boot order for the development machine, 
not the SSD disk that has be plugged in termporarily.   The answer is something simple, that I have not read about using before.  Or so obvious a child could do it. 
 

Mounting SSD /dev/da1 slices on USB Flash drive partitions

 ls /mnt
FreeBSD_Arm64s1
FreeBSD_Arm64s2
FreeBSD_Arm64s2a
mount -t msdos /dev/da1p4s1 /mnt/FreeBSD_Arm64s1 
mount  /dev/da1p4s2a  /mnt/FreeBSD_Arm64s2a
ls -l /mnt/FreeBSD_Arm64s1        notice all the boot files in the "MSDOSBOOT" directory 
ls -l /mnt/FreeBSD_Arms2a     notice the root "/" directory for the FreeBSD files and applications

Or should I write a manual, from notes? 
 
 
I am just lost, and looking to read to gain knowledge using  efibootmgr and efivarfs commands.
Could use a picture diagram made with DIA to explain relation ship of the parts and pieces.
