I'm working with a device (Buffalo Terastation TS1400D) that uses one of the SoC uart connections (uart1) to communicate with an on-board microcontroller which control some of the devices peripherals (fan speed, leds, buzzer etc). I'm able to send commands to it (and can see/hear that it's executing the) but I am not getting any of the acknowledgement messages back. When doing the same thing under the stock firmware everything works as expected in both directions.
I've got the same thing working perfectly on a very similar device (Buffalo Terastation TS3400D). Them main differences between them are that the 3400 is an armadaxp device and it uses uart3 rather than uart1 for this connection.
Has anyone run into a similar situation where they could only send data one-way like this?
