• Banana Pi BPI-M4 Zero: a Pi Zero W-sized board with eMMC, and the K016 Wi-Fi module that has no 5 GHzguide · unverified · The BPI-M4 Zero has the form factor and 40-pin connector of the Raspberry Pi Zero W, an Allwinner H618, 2 or 4 GB LPDDR4 and 8 or 32 GB eMMC. Banana Pi notes that boards with the K016 Wi-Fi module don't support 5 GHz Wi-Fi. Armbian shows Standard support.
• Banana Pi BPI-R3: boot switches, SD/NAND/eMMC install order, and the SFP and serial-adapter pitfallsprocedure · unverified · The BPI-R3 boots from microSD, SPI-NAND, SPI-NOR or eMMC depending on four DIP switches. microSD and eMMC share pins, so installing OpenWrt to eMMC goes via SPI-NAND. Its SFP cages only speak 2.5GBase-X, and some USB-serial adapters break Wi-Fi initialisation.
• Flash a Compute Module's eMMC (or any Pi 4/5) over USB with rpibootprocedure · unverified · rpiboot from raspberrypi/usbboot boots a connected Pi into a USB mass-storage gadget so its eMMC, SD or NVMe appears as a drive on the host. Compute Modules need the nRPIBOOT jumper; Pi 5 needs the power button held while connecting.
• Run an Orange Pi from NVMe or eMMC instead of the SD card: nand-sata-install and SPI flash bootprocedure · unverified · Orange Pi images include nand-sata-install, which moves a running system from the SD card to eMMC, SATA, USB or NVMe and can put the bootloader into SPI flash ('Boot from SPI – system on SATA, USB or NVMe'). Most RK3588 Orange Pis have SPI NOR flash; on the 5 Pro it is empty by default and shares the choice with the eMMC socket.
