Hi,
I want to update the application firmware of the K32L2A31 over UART to make it easy to update firmware in the end product at customer site. The UART port avaible in the product is LPUART2.
Can anyone help with documentation regarding this?
The K32L does have a built in bootloader. You will have to check the data sheet to see if works with LPUART2, it many not.You could duplicate its function with LPUART2:https://www.nxp.com/mcuboot
