GPIO programming from GOP driver on Bay Trail - T

[RAlev]

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

Hello Raghav_Alevoor,

Thank you for contacting Intel Embedded Community.

In order to help you please address your questions to the https://www-ssl.intel.com/content/www/us/en/forms/intelligent-systems/get-help-external.html Embedded Design Assistance, where you be connected with a representative in your area, who could possibly help with your project and/or a more appropriate processor selection. Because unfortunately the Bay Trail -T Z37xx is on the "off-roadmap" and its support is for limited manufacturers. For this reason, this processor is unsupported through this channel.
