Hello Andre,

Which MCUs are you speaking of? For MSP430, have you seen the BSL that is on chip? It is a simple protocol that can be implemented over UART/I2C/USB (dependent on device) from a host . You can find more information about the MSP430 BSL at http://ti.com/tool/mspbsl

Hi Andre,

if you meant one microcontroller is the host to update the other microcontroller, then the new Apps note from our colleague might help you: http://www.ti.com/lit/pdf/slaa755

On this Apps note, the host uses MSP432P SimpleLink MCU, and the target device to be updated is the MSP430.
