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.
我s there any way to program SRAM by SPI?
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
