I need to configure a dual screen on an IMX6S7CVM08AC:

   - first screen is connected through parallell port on IPU1_DI0

   - second screen is connected through an LVDS bridge on LVDS0

Since IPU1_DI0 is used by my first screen, i need to redirect IPU1_DI1 on LVDS0.


On the reference manual (IMX6SDLRM) chapter 40.5.1, the table 40-5 "Channel Mapping" suggest that it is not possible to use IPU1_DI1 with LVDS0 appart from dual mode or split mode.


I'm trying to use the dual mode but ch0_mode field value from LDB_CTRL stay at 01 instead of 11:


   /unit_tests/memtool -32 20E0008 1
   Reading 0x1 count starting at address 0x020E0008

   0x020E0008: 000002A5


Could someone confirm (or infirm) that IPU1_DI1 can be used on LVDS0 ?


Thanks in advance.
