Hi,

Is MK66FN2M0VLQ18 have the pre-installed bootloader in a chip(at the factory itself) or we need to write boot code for it.

Hello Sivakrishna,

 

This is possible using a bootloader. You can check our bootloader examples from the SDK, this bootloader supports loading data to flash via UART peripheral.

 

Please make sure you select mcu-boot in software components before downloading the SDK as the snippet below demonstrates.

For more information please visit the MCU-BOOT website below:

Hope it helps!

 

Best regards,

Felipe

Hi,

What are the hardware connections required for programming the flash using the UART interface?

Hi

The UART loader can be configured to use any UART interface/pin mux.
