MIKHALEV, Vasily <vasily.mikhalev@...>
I am developing for D2000 with Zephyr and I currently need to be able to write to the UART B and to monitor it. However, I cannot manage to do it.
For writing to the UAR I am using the function uart_poll_out(). For example.:
struct device *dev_b = device_get_binding("UART_1");
After flashing the program to D2000, I set the jumpers J9, J10, J11 in the CTS, TXD and N/C positions, open terminal on the virtual serial port, but it seems that there is no signal – nothing happens when I press the “reset” button . With the same settings I am able to monitor UART B of D2000 with QMSI. Also the same code works well for the UART A, e.g.:
struct device *dev_a = device_get_binding("UART_0");
Did anyone have the similar issues and was able to solve them?
I would really appreciate your help.
