Dennis Field / dvk-mx8m-bsb - History

Add IRQ# signal coming from the RTC, go over the SoM pins and fix lingering errors that are found

Modify the CSI circuit to use a 02x15 connector for potential use with the CO8725-B5SA-E camera, include cap touch FPC connector details, make minor adjustments to GNSS antenna circuit

Add WWAN and WLAN+BT MHF4 coax connectors and antennae symbols to the schematic, remove home and back buttons, reorder sheets so that GNSS is above the haptic motor sheet

Assign UART3 to the GNSS module, remove this UART3 from the WWAN M.2 and assign GPIO5_IO03 to DPR

Begin GNSS schematic using MAX-M8 module

Since UART2 isn't brought out then will either need to use UART1 (debug) with jumpers or the module's I2C interface.

Resolve merge conflict after pulling recent commit, now can no longer use SSH (since Gogs is getting abandoned?).

Add camera/CSI circuit, include second switch that is part of the audio+camera DPDT for killing both simultaneously, level shifters used for camera's I/O that requires it, footprints for a 1.8V LDO which may be used by DVDD will be included

External DVDD (1.8V LDO) needs to be tested if it's needed (datasheet says an internal DVDD can be used, as is the case with Boundary Devices' OV5640 camera).

Add bypass caps to logic gates used with the W_DISABLE and the 9-axis IMU's INT pins

Replace ICM-20948 IMU with the LSM90S1, replace RPR-0521RS prox+ambient light sensor with the VCNL4040

Nearly complete the LCD/DSI and cap-touch schematic, add notes from the display's datasheet regarding the various pin assignments, add component property information for the 39-pin DSI clamshell connector

Still need to determine what this requested "low power state signal" requirement is for the display.

Add LCD display's 22.4V (@40mA) LED backlight driver/boost converter IC circuit (PAM2841), selected the rectifying/schottky diode (SS14), and set the OVP to 37.6V as found on the IC's EVB
