Win32Imager definitely works better for my setup (and resulted in a
bootable SD card). I'm happy leaving the VM out of this part of the
process - detection and mounting of USB devices that get transferred to it
from the host is INCREDIBLY hit-or-miss on this VM.
First pass at running with a card processed by Win32Imager resulted in
failure (but I neglected to save out the logs). It booted (yay) and looked
like it had gotten just to where it wanted to begin writing from the image
on the USB stick and failed there with a kernel panic.
After that, I tried booting off of a flasher image uSD card, but apparently
the EEPROM had not been successfully written prior to the failure.
Re-built my USB stick and tried again, and it /looks/ like it's going
better:
- Serial monitor shows an fsck failure , but it continued ("error 2 (no
such file or directory) while executing fsck.ext4 for /dev/mmcblk0p1")
- Serial monitor stopped on "B" with the USR LED's cycling back and
forth in a "hey, world, I'm copying your image!" way that I like to see.
LED's eventually settled at "all on", so I've powered down, pulled the uSD
cards, put power back in and it /looks/ like it's running from the LEDs, but
* No output on the serial console
After one more hard power cycle (failed to respond to power button) the USB
network adapter showed up in Windows (still no console output?) and I can
SSH into the board.
I think that's got me running - now to verify it on a few more boards in my
pile.
Much thanks, Robert.
