Hi dialog,
We have the DA14581 without flash. We want to use the flash on another board(master) to program the code to DA14581(slave) SRAM by using SPI interface.
有程序存储器通过SPI方式吗?
Thanks a lot.

Hi feaethan,
When the 581 is power up the ROM bootloader runs and goes through a procedure where all the pins in port zero are scanned with different interface configuration (including SPI slave) in order to download code to the sysram. Please have a look at the AN-B-001 - Booting from serial interfaces for details on the Primary Bootloader procedure.
Thanks MT_dialog
