Hi Team,

Hi Sravan,

Yes, MCUboot can use/access Zephyr drivers, but please note that MCUboot serial recovery in NCS v3.2.1 supports only UART/USB CDC ACM. If you have other requirements with I2C in MCUboot that you want to implement yourself accessing the drivers, then you should be able to do that.

Ok, I am using 3.1.0 SDK...... I want to access I2C and SPI drivers in mcuboot, I can be able access right without any issues?

Their initialization and transactions on those serial peripherals can cause delays in the system boot up time, but apart from that , I do not see why you cannot access those peripherals in mcuboot.
