can’t be supported by the SoC than an alternative GPIO or No-Connect is allowed by the specifications.
The DB8 implements two CSI clocks, CAM_MCLK0 via APQ GPIO_13 for CSI0 and CAM_MCLK2via APQ GPIO_15 for
CSI1. These signals are driven at 1.8V.
7.1.8 USB
The 96Boards specification calls for a USB Data line interface to be present on the High Speed Expansion Connector.
The DB8 implements this requirement by routing USB channel 3 from the USB HUB to the High Speed Expansion
Connector.
7.2 Secondary High Speed Connector
Given the extensive I/O available on the APQ8096, a second high speed connector(on carrierboard-J20) has been added
to support additional interfaces for development and integration.
Currently, the SW supporting these features is pre-commercial and many features are not implemented. Refer to the
notes section in the table regarding SW support.
While there are functions assigned for primary usages such as I2C bus, SPI bus, etc., most pins can be repurposed as
GPIOs if needed and their GPIO # assignments are included for reference. The following table shows the Secondary
High Speed Expansion Connector pin out:
