Yes. That’s indeed the link I put in my original post.

Yes, except that what they talk about zeroing out the boot loader on the *eMMC*
(not the SD card). I do want to keep the eMMC-resident boot loader, and based
on what that documentation says, that’s OK and only requires pushing the
user/boot button (which I did).

That’d be great. I’ve gotten to the point now that I can insert the card to a
running system on the BBB for inspection, without crashing it as a result. I
downloaded the image again, this time using curl, and then burned it to the SD
card again. Now the partition layout shows as they say it should:
$ sudo fdisk -l /dev/mmcblk0
Disk /dev/mmcblk0: 32.2 GB, 32227983360 bytes
4 heads, 32 sectors/track, 491760 cylinders, total 62945280 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xa3c9235b
Device Boot Start End Blocks Id System
/dev/mmcblk0p1 * 8192 270335 131072 c W95 FAT32 (LBA)
/dev/mmcblk0p2 270336 2367487 1048576 83 Linux
/dev/mmcblk0p3 2367488 4464639 1048576 83 Linux
/dev/mmcblk0p4 4464640 7614463 1574912 83 Linux
The p2 and p3 partitions are labeled system-a and system-b, p4 is labeled
‘writable’ and p1 is labeled system-boot, all as they are supposed to be. p1 is
bootable.
However, booting from it still fails. No LEDs ever light, everything except the
power LED stays dark.
