Inquiry on UART-Based Bootloader Development for ADuC7061

Question

Hi There, 
 I have a question regarding bootloader development for the ADuC7061. 
 I&rsquo;d like to understand whether it is possible to load firmware over UART and, if so, how this can be done. I would really appreciate any guidance, documentation, or example regarding bootloader development for this MCU. 
 Best, Farshid

Response to Question 1: Yes, the serial download protocol would require the BM + reset. 
 Response to Question 2-5: 
 It's possible to implement In-Application Programming (IAP), if the BM and reset pins are not accessible. Please refer to link: Implementing In-Application Programming on the ADuC702x | Analog Devices 
 The link is referencing ADuC702x, but ADuC7060 should still work. There is also an example at the end of the page. Take note that flash of ADuC7060 is smaller than ADuC7020. 
 If the JTAG pins are exposed, this is another possible approach.)
