Hi,

 

We are using android_p9.0.0_2.1.0-auto-ga BSP for iMX8QM Custom Board, in which its unable to configure high/low for GPIO pins in U-boot. But we change to use android_p9.0.0_2.0.0-ga and L4.14.98_2.0.0, we can success to set high/low for same PINs in U-boot.

 

Example:

We try to set SC_P_SPI3_CS1_LSIO_GPIO2_IO21 to high and work good in android_p9.0.0_2.0.0-ga and L4.14.98_2.0.0.

But failed in android_p9.0.0_2.1.0-auto-ga. 

 

How to solve this problem?

Thanks.
