I can use bootloader in uart, but i can't use bootloader in rs485

   

Seems to be because the relationship RS485 half-duplex

   

How do I fix this problem?

Bootloading should also work with half-duplex communication. Its just that there is no example for that (AFAIK). So you would need to write your own bootloader component.

The physical layer of RS485 vs 422 impacts the transceiver

   

signaling, hence firmware. See en.wikipedia.org/wiki/RS-485

   

So you would have to modify UART APIs put a firmware wrapper

   

around it.

 The current UART bootloader is for full duplex mode. There are a couple of modifications needed for the half duplex mode.
