The goal of the document is to illustrate how to build SP7021 Linux image for booting from eMMC device on SP7021 boards, and how to write SP7021 images to the eMMC device.
...
“ISP all: Done” means all images were written to eMMC successfully.
Note that in-system-program (ISP) of SP7021 does not support USB hub. The USB flash drive for ISP should be plugged into USB socket of SP7021 board directly.
If you are using Banana Pi BPI-F2P boards, please plug you USB flash drive to the micro USB socket for ISP. It is the only USB socket that is connected to SP7021 directly.
8. Boot Linux from eMMC device
...
DIP-SW is set to OFF-OFF. Now, you are ready to boot SP7021 Linux from eMMC device. Turn on power of SP7021 board again to boot system.
9. In-system program (ISP) from an SD card
Note that you can also copy your ISPBOOOT.BIN file to root directory of a micro SD card to do in-system-program to eMMC device. The SD card be formatted to DOS/Windows FAT32 file-system. Note that SP7021 only detects ISPBOOOT.BIN in the first partition.
Set DIP-SW (boot-select switch) to “boot from SD card”. For example, if you are using SP7021 Demo Board (V1/V2/V3), please set DIP-SW to ON-ON (0-0) for booting from SD card.
Plug your SD card into micro SD socket of SP7021 board, install UART console, and then turn on power of SP7021 board. SP7021 will start to do ISP from SD card.
