Put your SPI-NOR flash chip into socket of flash programmer. Be careful about the pin 1 position of the chip. It should be at the same corner of pin 1 of socket. Refer to picture below, an SPI-NOR flash is placed at socket of a GZUT USB flash programmer.
...
Run flash programmer application, for example, run GZUT_OnePro in Windows. After application window pops up, then load binary file, spi_all.bin. Press “Auto” to start to write processes automatically (including erase, write and verify). Refer to screenshot below, a WINBOND Winbond 128 Mibit (16 MiB) flash chip (W25Q128) has been programmed and verified successfully.
...
Remove the SPI-NOR flash chip from socket. Plug the written SPI-NOR flash into socket of SPI-NOR flash of SP7021 board.
Note that the size of 'spi_all.bin' is about 1410.2 MiB. So, size of SPI-NOR flash chip should be 16 MiB (or 128 Mibit) or greater.

8. Set DIP-SW to “boot from SPI-NOR flash”
Plug the written SPI-NOR flash into socket of SPI NOR flash of SP7021 board. Set DIP-SW (boot-select switch) to “boot from SPI-NOR flash”. For example, if you are using SP7021 Ev Board, please set DIP-SW to OFF-OFF-ON-OFF-ON-OFF (1-1-0-1-0-1) for booting from SPI-NOR flash. Refer to picture below, DIP-SW is set to OFF-OFF-ON-OFF-ON-OFF.
