Hi @FelipeMdeO ! Adding to what @eren-terzioglu said: SPI is a full-duplex bus, so it's expected that the first exchange receives all zeros from the slave device (even running the tx/rx copy example). The slave device is just transmitting the content of the its TX buffer. Running the example on master for the second time, slave will transmit the data it received in the first execution. This is the expected behavior. I will close this issue for now. Please let me know if you find anything else different from the expected behavior. -- This is an automated message from the Apache Git Service.
