I am working on a project related to the Modbus serial.
HW setup:
The custom board based on nrf9160 IC with LTC2873 [used for toggling between RS232 and RS485 connection] where Modbus UART from nrf9160 is connected to this USB converter and a separate Jlink is used for programming.
SW setup:
Latest mainline Zephyr and 0.16.1 SDK
issue:
Making hardware connections for RS485 with the USB to RS232/RS485 converter's USB end left open/ not connected to any devices and selecting RS232 in software configuration for
tests/subsys/modbus/
application causes stack corruption and device reboots.Output:
