Booting from eMMC

• Enable to boot from eMMC is more convenient since it asks to clear SPIflash. Therefore, we can easily to switch to boot from eMMC or SD card.
  • By default SD card has a higher priority to boot than eMMC.
  • I can use eMMC as the main OS storage and use SD card to play with different OSs.
  • Even I follow the instruction to use RKDevTool to put a Linux image onto eMMC, I still cannot boot from eMMC until I clear SPIflash.
  • eMMC is /dev/mmcblk1, speed is 271 MB/s (sudo hdparm -t --direct /dev/mmcblk1p2 )
  • SD is /dev/mmcblk0, speed is 62 MB/s (sudo hdparm -t --direct /dev/mmcblk0p2 )

• From Linux

$ ls -l /dev/mtdblock0
brw-rw---- 1 root disk 31, 0 Dec 10 06:00 /dev/mtdblock0

• If you want to boot from eMMC on the Orange Pi 5 Plus, you would need to clear the /dev/mtdblock0 partition. This is because the /dev/mtdblock0 partition typically contains the bootloader, and clearing it allows you to install a new bootloader that can boot from the eMMC.
  • Here is a general guide on how you can do this: Boot Armbian from an SD card.
  • Clear the SPI flash memory by running the following command in the terminal: sudo dd if=/dev/zero of=/dev/mtdblock0 bs=1M count=1

Booting from NVME

• The instruction on wiki How to burn Linux image to SPIFlash+NVMe SSD->The method of using the dd command to burn works when I tested on Debian 11 KDE Plasma installed on a SD card.
  1. burn the u-boot image into the SPI Flash

     sudo nand-sata-install
     # select 7 Install/Update ther bootloader on SPI Flash

  2. use 'dd' to clear the NVMe SSD & burn the linux image to NVME SSD
• The NVME speed is 2046 MB/s by using the command sudo hdparm -t --direct /dev/nvme0n1p2 . The NVME is inland TN450 (500GB).
• What is /dev/mtdblock0
  • In the context of the Orange Pi 5 Plus, the /dev/mtdblock0 partition is used to store the bootloader.
  • Booting directly from a USB or NVMe requires flashing U-Boot to the SPI.
