I am working on RS485 support on IMX6Q + Yocto1.7 for some days, but it can't send data while receiving is OK. I am using minicom on both RS485 sides. I've read topics on this community about RS485 but they doesn't help yet. Please give me some advise.
BTW, must RS485 work in 9-bit multidrop mode? that is, bit 9 is used to transfer slave address? thanks a lot.
