    GPIO programming from GOP driver on Bay Trail - T

    Raghav_Alevoor Green Belt

      Hi,

       

      We are developing our product using Bay Trail - T Z3745 chipset. We are interfacing a MIPI panel in our product.

      LCD enable pin is controlled by PMIC. The LCD reset pin is connected to GPIO 58 of South Cluster. LCD Bias enable pin is connected to GPIO 94 of South Cluster.

       

      The GOP driver version is 7.2.1008. The panel power up, power down sequence is added to vbt.bin and the panel configurations are updated using BMP tool. New UEFI image is generated for our platform. During the board boot we observed that the state of GPIO 58 and 94 are not changed according to the panel initialization sequence.

       

      Does the GOP driver for Bay Trail - T Z37XX support GPIO configuration of South Cluster?

       

      Regards,

      Raghav
