Hi,
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. Is it possible?
Thank you
Marco
Hi @mangramarco ,
yes, you can use the KBOOT for this (see https://mcuoneclipse.com/2018/03/03/flash-resident-usb-hid-bootloader-with-the-nxp-kinetis-k22-micro... where I used it with USB CDC). That bootloader from NXP supports different loading interfaces like USB, SPI, I2C and as well UART.
I hope this helps,
Erich
