HOWTO make a BeagleBone Black be a flash drive for Xbox modding
If you're wanting to softmod an original xbox, the procedure involves using a small USB flash drive to function as a memory unit in order to get a carefully-crafted save file into the system.
I didn't have a USB flash drive small enough to work, but I do have some BeagleBone Blacks around.
I was able to make a BeagleBone Black act convincingly like a 512MB flash drive with the following process:
You'll probably want to have a external FTDI cable, as this process disables the serial and network interfaces over USB. However, with this setup, I was able to have the Xbox recognize the flash drive as a memory unit and reformat it. ("The memory unit you inserted isn't working correctly. It has been erased.")

I was able to make a BeagleBone Black act convincingly like a 512MB flash drive with the following process:
- Grab a firmware image and put it on an SD card. I used "AM3358 Debian 10.3 2020-04-06 4GB SD IoT", which was the current version at the time of this writing.
- In
/etc/defaut/bb-boot:- set
USB_NETWORK_DISABLED=yes
- set
- In
/opt/scripts/boot/am335x_evm.sh:- change
usb_ms_ro=1to0 - comment out or remove the following lines for the serial gadget function in
run_libcomposite:#mkdir -p functions/acm.usb0#ln -s functions/acm.usb0 configs/c.1
- change
- By default we load cape overlays, but we don't have any capes, so to improve boot time, in
/boot/uEnv.txt:- change
enable_uboot_overlays=1to0 - change
enable_uboot_cape_universal=1toenable_uboot_cape_universal=0
- change
- Set up the image file with:
rm /var/local/bb_usb_mass_storage.imgdd if=/dev/zero of=/var/local/bb_usb_mass_storage.img bs=1024 count=524288mkfs.vfat /var/local/bb_usb_mass_storage.img
