RX71m SCI boot

Hello,

You can use as reference the application note below, that implements a SCI bootloader on RX140:

Ιt uses Xmodem protocol to transfer the image from the user's PC folder location to the internal flash of the RX.

Also, on the link below, you can find the projectd for the bootloader and for the application on CS+:

Τhe same idea can be implemented on RX71M.

Hi AL_Renesas San,

Thanks for the replay,

Actually, i was expected the replay Which is given By JimBsan

But The response given by you is more interested can you please check & confirm details..

please confirm i will explain what i understand,

1. First we have to define Boot loader Program with condition of checking input from user for updating firmware or not .

2. load the boot loader program on the MCU using Debugger (E2 lite,E1 etc).

3.  Restart the MCU Generate the condition of erasing application Code & update previous code with new One.

Now the my question is that 

Is we need to use any dedicated port for SCI
