Hi,
imx8mm to connect with radar sensor through csi2，Radar output Bayer type data，I can receive the data, The data in the first frame is incomplete, and the other data is completely correct from the second frame, but CSI2 will prompt: Lost Frame Start Error events，
After the radar is powered on, it starts to transmit data through CSI2, imx8mm cannot determine whether it is receiving from the beginning of a frame.I think it is normal to prompt this error once, but the above picture prompts 243 times。
In order to ensure that the first frame of data received is also correct, my method is to start receiving data after detecting the start of the frame., I modified mx6s_capture.c as follows:
1、enable Start Of Frame Interrupt，set SOF_INTEN bit，then disable DMA_REQ_EN_RFF interrupt.
RFF
2、In the Start Of Frame Interrupt processing function，clear the FIFO enable DMA_REQ_EN_RFF，Start receiving
In function mx6s_capture.c -> mx6s_csi_irq_handler
But the error has not changed, the first frame of receipt is still incorrect.
I need your help. One is how to solve this error, and the other is whether this method can achieve the first frame of data is complete
The attachment is the source code of my program。
thank you
