stm32f769 dsi application problems

Dear:

   I am working on STM32F769 development board with the dsi unit.

   I set the dsi clk to non-continuous mode and set dsi to LP command mode.

  Then I  inited  the dsi module and started the DSI calling the the function HAL_DSI_Start(), there was something wrong with the clk lane. When the function HAL_DSI_Start() is called, sometimes the clk lane went into HS mode but there was no data on the data lane. It does not happen each time.

    I don't know why and how to solve the problem or explain it.

    Any help would be greatly appreciated. I am looking forward for you reply.
