As shown in Figure 2-31, there are 4 resistor arrays footprint and 2 resistor arrays used as pinmux between board edge interface, HSEC, and on-board SD card holder, MMC0. From TIDM-02009 and its design files, it is found that the board edge pins are required to connect some gate driver pins. The pinux configuration should be confirmed before moving forward.
