The settings do look the same

cat /boot/extlinux/extlinux.conf

MENU TITLE L4T boot options

      MENU LABEL primary kernel
      LINUX /boot/Image

# When testing a custom kernel, it is recommended that you create a backup of
# the original kernel and add a new entry to this file so that the device can
# fallback to the original kernel. To do this:
#
# 1, Make a backup of the original kernel
#      sudo cp /boot/Image /boot/Image.backup
#
# 2, Copy your custom kernel into /boot/Image
#
# 3, Uncomment below menu setting lines for the original kernel
#
# 4, Reboot

# LABEL backup
#    MENU LABEL backup kernel
#    LINUX /boot/Image.backup
#    INITRD /boot/initrd
#    APPEND ${cbootargs}

	MENU LABEL Custom Header Config: <HDR40 User Custom [2021-11-24-085933]>
	LINUX /boot/Image
	FDT /boot/tegra210-p3448-0000-p3449-0000-b00-user-custom.dtb

But when I try the following command:

sudo ./spidev_test -D /dev/spidev0.0 -g16 -zz

It uses SPI 2.0 again. Perhaps because I don’t have a /dev/ folder within my spitest library
