= Testing driver =

To make sure than driver works well, make the next test, i . I used GPIO_136(sdmmc2_dat4) and GPIO_137(sdmmc2_dat5) because IGEP v2 RC5(without WIFI) don't use them by default: <br>

'''NOTE:''' For more information visit this [[Mux configuration|page]]. <br>

signals: sdmmc2_dat5 | sdmmc2_dir_dat1 | cam_global_reset | sdmmc3_dat1 | gpio_137 | hsusb3_tll_stp | mm3_rxdp | safe_mode

</pre>

Note: OMAP_PIN_INPUT=Input/Output pin and OMAP_PIN_OUTPUT=Output pin, for read/write test you need the first one. GPIO is configured in mode 4.<br>
