Odroid m1 petitboot update

I’m trying to update the firmware on my Odroid-m1 after the latest os update broke my system.
I’m trying to follow the instructions here:

github.com/home-assistant/operating-system

Documentation/boards/hardkernel/odroid-m1.md

# ODROID-M1

Home Assistant OS 10 and newer support the ODROID-M1 board.

## SD-card

SD-card boot is supported via on-board bootloader (SPL) or recovery button.

## eMMC

eMMC boot via on-board bootloader requires a newer version of Petitboot
(spiboot 20230328 or later). To install the latest version download the SPI boot image
from [linuxfactory.or.kr][1] as follows:

1. Download `spiupdate_odroidm1_20240415.img.xz`
2. Use balenaEtcher or another tool to flash the updater onto an SD card
3. Download `spiboot-20240109.img`
4. Rename the `spiboot-20240109.img` file to`spiboot.img`.
5. Paste the `spiboot.img` file onto the FAT partition of that same SD card.
6. Plug-in that SD card to your ODROID-M1. Petitboot will update itself, you can verify the progress on the HDMI output.

This file has been truncated. show original

But after using Etcher to create the SD image, there is no FAT partition to copy the spiboot image to.
What am I doing wrong?

It is vfat.
On Linux You should see something like:

cat /proc/mounts

/dev/mmcblk0p1 /run/media/mountpoint/Id vfat
