What's state does the spi pin when copy image from flash to sram completed?

年代ince I used the spi bus in my project, and I want to add the spi flash too, So I think when code copy finished, the rom bootloader should put the spi flash into sleep state and my application configure the spi bus to different pin set. So my question is when the spi has been mapped to new pin after code copy finished, will the boot pin P0.0 P0.3 P0.5 P0.6 influence the power consumption?

Device:

DA14580

Hi cgha,

Hi cgha,

请看看AN-B-001 : DA14580/581/583 Booting from serial interfacesuser manual form our support website. It is mentioned that upon completion of the SPI master process, all related pads are set to input and pulled down.

Thanks, PM_Dialog

Thanks, now I see the pads

Thanks, the an-b-001 note if the DA14580 act as spi slave, after complete, the pads are set input and pulled down, does this also applicable to other scenarios?

Hi cgha,

Hi cgha,

Yes, the GPIOs will remain input and pulldown after the device boots up.

Thanks, PM_Dialog
