[Fb62]

Hi

it's possible configure the FOTA bootloader (SMP service) whit only one partition, for large application.

I using the nRF52-DK and have only 512KB of flash, and my application is more of 256K

Thanks

Hi Fausto,

Do you mean image slots? Two image slots are a mandatory requirement by mcuboot. If the flash size is not enough, you have to think about other MCU(like nRF52840 with 1MB flash) or adding an external flash chip according to your needs.

Best regards,

Charlie

Hi,

How do I add external memory  and how do I configure zephyr and mcuboot to use external memory?

Thanks in advance.
