Robert Lipe notes that Apple hardware and Nezha D1 do not work together using a USB-C to USB-C cable. It should be possible to work around the problem using the USB-A to USB-C cable(s) supplied with the board.
Kernel 5.4.61 (as reported by Gabe R):
mtd0: 00100000 00040000 "boot0" mtd1: 00400000 00040000 "uboot" mtd2: 00100000 00040000 "secure_storage" mtd3: 0fa00000 00040000 "sys"
Kernel 5.16.0-rc2:
# cat /proc/mtd dev: size erasesize name mtd0: 10000000 00020000 "spi0.0"
The USB serial adapter that comes with the board connects to the 3-pin "DEBUG" header on the board as follows:
Peter Gutmann notes that the supplied serial cable can be faulty. If this is the case, it needs to be replaced with a serial adapter that uses 3.3V levels.
With kernel 5.16.0 (which is available in some disk images and does not boot by default) it is possible to control the RGB LED of the board, which is labelled "LED" and sits next to the red "PWR" LED:
LED=/sys/class/leds/rgb:indicator echo 0 50 50 >"$LED"/multi_intensity echo mmc0 >"$LED"/trigger
