I trying to implement bootloader in my project using the UART component. In did a few projects with RS232 and i2c and all worked OK, I guess it's not working because RS485 is half duplex . i didn't find any code example for that kind of bootloader...
Yes you are right. Since RS485 is a half duplex communication, you need to configure your UART component correspondingly. There are no official code examples from Cypress, but you can find your solution here on the thread below:
