Adding a Magic Probe Debugger to Raspberry Pi 4B

Image
 Adding a Magic Probe Debugger to Raspberry Pi 4B First test booting a Raspberry Pi 4B into Single User mode in FreeBSD 14.0  https://www.linux-magazine.com/Issues/2019/223/Desktop-FreeBSD    I managed to boot to another drive and edit loader.conf:   beastie_disable="NO"  loader_color="YES"   The beastie_disable="YES" allowed me to boot to single user mode, the loader_color="NO" seems to have enabled more verbosity in the log. It then became apparent it was trying to mount the external USB HDD that I had added to /etc/fstab . Annoying that with beastie disabled it did not give any error. Regardless, I added noauto to the fstab entry and rebooted, but it still failed to mount the drive, so I tried commenting out the entire entry for my hdd. This allowed it to boot to a login prompt.   # Disable the beastie menu and color beastie_disable = "YES" loader_color = "NO"     https://forums.freebsd.org/threads/...

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 Free...

Download  a FreeBSD 14.0 Current version for Raspberry Pi Here below,  I used Manjaro Linux to download and write an .IMG file to a microSD card.  I have also used GhostBSD.org Operating System as my base development system to do the same thing.   The commands are slightly different to perform the same task.  Like sha256, sha512 commands for GhostBSD and sha256sum, sha512sum for Manjaro Linux. My non functional USB Keyboard problem details, referenced in URLS I see some numbers and text fly by on the HDMI Monitor with Raspberry Pi 4B, yet could not type on the USB keyboard and enter some characters to login at the login prompt.  The keyboard was non responsive.  The February 2021 FreeBSD snapshots did not have the correct start4.elf file.
