hi expert

sdk8.2 qnx +rtos

i have some question about csitx

the ife error is 0x10000ff

1.When I use the csitx interface of tda4, if an IFE error occurs on the other end, is there a way for tda4 to determine whether there is an error in CSItX and the reason for the error?

2.If an IFE error occurs How should TDA4 be handled?

3.What should be done if an IFE error occurs on the other end and TDA4 CSITX does not report an error?

4.If I want to monitor the data transmission status of CSITX, is there a recommended register or program interfaces？The Frame Queue Count information is too limited.

Additionally, it has been found that some related registers can be seen in TRM but the specific meanings of the registers are unknown. Can you provide the meanings of the relevant registers,

such as CSI_ TX_ IF_ DPHY_ STATUS: DPHY_ ULPS and DPHY_ STOPSTATE

Hi Yao Zhang,

What is the IFE error? Can you please provide some more information?

In general, CSITX is a transmitter, since it is starting point, it shouldn't have any errors and so it does not report any error. CSIRX reports error related to FIFO, some count mismatch, but nothing else.
