That bootloader from NXP supports different loading interfaces like USB, SPI, I2C and as well UART.</P><P>I hope this helps,</P><P>Erich</P> Thu, 03 Jun 2021 10:31:07 GMT ErichStyger 2021-06-03T10:31:07Z There is a way to program k22 via uart2? https://community.nxp.com/t5/Kinetis-Microcontrollers/There-is-a-way-to-program-k22-via-uart2/m-p/1286732#M60704 <P>Hi,</P><P>i've a board with k22 mcu. This communicate with other mcu by means of uart2 and there is not any other external communication implemented. I want to update the firmware of k22 passing through other mcu.
