hi expert

sdk8.2 qnx+rtox

I want to use registers to monitor the status of CSITX sending data ，In TRM describes some registers linke CSI_TX_IF_DPHY_STATUS but there is no specific BIT to represent its meaning. I would like to know the meaning of each bit

Please help recommend several registers that can monitor the status of CSITX

Hi Yao Zhang,

CSITX uses DMA engine to read and to transmit the data, so can you use DMA completion event to know if it is transmitted? CSITX driver provides DMA completion event callback to the application, you can use it to know the transmission status.

Is this what you are looking for?

hi expert

thanks for your replay

I think DMA is only for data transfer and cannot determine the integrity and validity of the data;
I want to monitor or determine if the data sent by CSITX is complete, and if there are similar registers to check
