Hi everyone,

I am new to kinetis and MQX and I have some questions about bootloader and MQX.


I am using the TWR-K64F120M and MQX from the KSDK.

I want to know what is the best practice to use a (custom)bootloader and MQX :


- Is there any interest to keep bootloader's RAM (data) when the MQX user application is in activity?

- Does it is necessary to put bootloader's code in RAM for launching MQX application?

- Is there a way to "exit" MQX application and come back to bootloader whitout using reset (neither soft or hard)?

- What about the position of bootloader configuration data in flash? Does it is necessary to put it at the end of the flash?


Thanks for your help
