The rom on cpu boot order (to find idbloader & then uboot) is SPI, emmc, uSD, usb for emmc/SPI write
Once uboot is found, its' boot order is used, usually (varies) uSD, usb, network, nvme, emmc
An experiment for you,,, zero with fdisk a uSD (note numbers so you can restore),
NOT mrfixit because it hasn't had uboot updated, insert usb stick and uSD
Maybe the usb stick will boot
It is really odd that mrfixit did not work
Boot rom (on cpu) looks for signature of idbloader 64 sectors, raw read, no FS, in boot order
From that media, uboot is read (and ATF maybe) then uboot searches filesystems for extlinux or boot.scr,
in its' boot order
BTW, try with BOTH usb sockets, I seem to recall often only 1 works and not other, not consistently
Oh, don't try sd -> usb adapter, I've never had that work--- for booting
----
BTW, any uboot should make green light (manjaro=red,then grn) come on.. I assume you see this?
