how to use "tower bootloader" to download programs via RS485?

[wangb]

I want to use "tower bootloader" to download programs to my board (MKV30)through serial port(UART), but I found that my serial port(UART) is RS485 .In "tower bootloader", how do I need to modify in order to achieve RS485 communication,and  is there any information in this respect that can be provided to me?

Hi Wangb,

Tower board doesn't support RS485. You have to add a converter to connect RS485 and UART.
