Boot from SPI Flash

Hi,

I am using custom board with DA 14585 chip. I have configured P0_0 as CLK, P0_1 as CS, P0_2 as MISO and P0_3 as MOSI. The firmware is copied into flash using smart snippets toolbox. The requirement is to boot the device from flash. But, this is not happening. Is it because the of the pins configured ?
Is it mandatory to use P0_0 as CLK, P0_3 as CS, P0_6 as MOSI, and P0_5 as MISO, for the device to boot from flash ?

Thanks
Wisilica

Hi wisilica,

The 585 can boot as from an SPI master from 2 sets of specific pins, the pins that can be used are documented in the UM-B-079 DA14585 586 SDK 6 Software Platform Reference.pdf in appendix G on Table 38. But when it comes to boot from a flash memory, the memory should act as a slave and the 585 as a master, and there is only one option for this kind of configuration, the pins that you have selected are only when booting from a master.
