No packets in SPI

[FoolBridgeRectifier]

Hi, I have a problem with reading data on pi 3. It was working fine until last week, but suddenly no data came. I checked the SPI ports using spidev_test and it works. And it works with other codes such as pylepton code, my client code is based on this so it is hectic to change. I checked the packetNumber under LeptonReadSegment() and it is never equal to j hence it keeps resetting.

That is a strange behaviour, it never happened to me. However, you are the second person telling me that the code stopped working suddenly. Any recent drivers updates ? new devices using I2C or SPI ? I had a similar issue when I was using the I2C for another sensor from a different app.
