Dennis Field / dvk-mx8m-bsb - History

Add notes regarding I2C's 3V3_OUT supply and the fact that it is sourced from NVCC_3P3 (3A BUCK6), add additional notes regarding the RTC and Camera's I2C slave address, reannotate the whole schematic (nearly the last time)

Include address in schematic notes for all I2C1 slaves, make HDMI connector shielding resistor to GND 0Ohms

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

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

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

Modify the boot config/boot mode pins and switch such that only eMMC and USB (serial downloader) are boot options due to the uSD being attached to the USB<->SD bridge chip, add OV5460 notes about using the internal DVDD 1.5V regulator

Add smart card circuit using the SEC1110 USB to ISO/IEC 7816 bridge chip, include ID-0001/2FF/mini-SIM socket connector selection informatino (1010027182)

Need to create footprint for the mini-SIM socket
