RS485 on i.mx6sx

[kubiznak_petr]

On some processors (e.g. Vybrid VF6), it is possible to use the RTS signal for RS485 transceiver output control. I'm struggling trying to do the same on i.MX6SX. It seems to be achievable with the CTS signal though. Is it possible to configure the RTS pin for this functionality?

Hi kubiznak_petr

one can consider control of DCE/DTE mode described in

Figure 65-2. UART external signals to module signals routing with respect to DCE/DTE mode

i.MX 6SoloX Applications Processor Reference Manual

Hi igor,

Thanks for your reply. That looks promissing but then the issue would be that the RX/TX signals would be switched too, right? Or is it possible to only switch RTS<->CTS in software?

Hi kubiznak_petr

unfortunately it is not possible only switch RTS<->CTS in software.
