Hi, I'm trying to configure buitin UART (carambola 2) to work at 9600bps, 1 stop bit, even parity and 7 bits. I can't achieve this. Here is different combinations that I tried. toptions.c_cflag &= ~PARENB; toptions.c_cflag |= PARODD; // cause no parity toptions.c_cflag &= ~PARENB; toptions.c_cflag &= ~PARODD; // cause no parity toptions.c_cflag |= PARENB; toptions.c_cflag |= PARODD; // cause no parity toptions.c_cflag |= PARENB; toptions.c_cflag &= ~PARODD; // cause odd parity With logic analyzer I read packets and see that I can set only ODD parity or no parity at all. There is no way to get EVEN parity. The same result I get both with my own code and with stty tool. Is there any issue in driver? According to pdf from here (viewtopic.php?f=5&t=396) this Atheros should support even parity mode. Plus I can't set 7 bits per message. Is this supported by this UART? |

Did you rebuild kernel to don't use serial console ? |
