STM32H747 MIPI DSI Command mode

[NHo.1]

HI ST,

I do a project about MIPI DSI but have an issue:

• when send the first command DSI in command mode, status is HAL_OK and I see the signal on scope (DSI D0P/D0N). After that, Pin DSI D0P/D0N is in level 0 and don't send the next command.

DSI Config: DSI_Clock_land_byte = 38MHz, TXEscapeCkdiv = 0x09

PhyTimings.ClockLaneHS2LPTime = 35;

  PhyTimings.ClockLaneLP2HSTime = 35;

  PhyTimings.DataLaneHS2LPTime = 35;

  PhyTimings.DataLaneLP2HSTime = 35;

  PhyTimings.DataLaneMaxReadTime = 0;

  PhyTimings.StopWaitTime = 10;

  HAL_DSI_ConfigPhyTimer(&hlcd_dsi, &PhyTimings);

Please help me, thank you.
