Hi,
I'm looking into using the SCI bootloader to perform OTA updates over a RS-422 or RS-485 link.
If I use RS-485, the SCI bootloader needs to implement a "direction control" GPIO output to control the RS-485 transceiver; to switch between sending and receiving mode. Does the SCI bootloader support this? If not, is there any practical way to use the SCI bootloader over RS-485?
I've seen posts like this:
https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/491666/c200-sci-bootloader---over-rs485
but they don't clearly state if the SCI bootloader has a direction control output.
Thanks,
-Greg
