@EtchedPixels' recent commits resolved all the problems I had in my other issue and now both the build and burn processes work as expected.

By running dd if=FUZIX/Images/esp8266/disk.img of=/dev/sda I successfully created a bootable FUZIX SD card. Contrary to what the documentation states, in my particular case, the microSD module's VCC needed to be connected to 5V (not 3.3V) for D1 mini to be able to find and boot the file system.

After boot, the kernel panics with the following exception:

Devboot
Allocated 27 disk buffers.
128KiB total RAM, 96KiB available to processes (15 processes max)
Enabling interrupts ... ok.
NAND flash, 1421kB: hda:
SD drive 0: hdb: hdb1 hdb2 (swap)
Mounting root fs (root_dev=17, ro): OK
Starting /init

Sidenote: The documentation's commands need to be updated too (make -C Kernel/platform-esp8266 burn to make -C Kernel/platform/platform-esp8266 burn).
