i.mx8 mini i2c on Windows IoT

Hi:

We are using i.mx8 mini WoA solution (win10 IoT).

In the i.mx8 mini datasheet, it says i.mx8-mini has 4 i2c buses,

But in the device manager, it shows the system has only 2 i2c buses only,

 

How do we enable the other 2 i2c buses to the system?

Hi Chang Chris,
The i2c drivers are loaded based on information entered in
"mu_platform_nxp/NXP/MX8M_MINI_EVK/AcpiTables/Dsdt-I2c.asl" ACPI table. If you add or remove a device, remember to also enable it's clocks, powers and route and configure pins correctly. For this setup look at "VOID I2cInit()" inside "mu_platform_nxp/NXP/MX8M_MINI_EVK/Library/iMX8BoardLib/iMX8BoardInit.c".

Also I am sorry for such late answer. Will try to ping someone to watch for Windows related posts inside i.MX8 Coral Dev kit too. The usual place to find Windows IOT related posts is here:
