I am checking the colibri imx6ULL datasheet. It says that there are 3 SPI controllers available: ecspi1,2,3. Table 5-25 shows the ecspi2.MOSI, ecspi2.MISO, ecspi2.SS0 and ecspi2.SCLK are “not connected on module with Wi-Fi”. Here are my questions:
- Since imx6ULL has built-in WiFi, does that mean ecspi2 is not available too?
- The additional slave select signals ( ecspi1.SS1, ecspi1.SS2 and ecspi1.SS3) share same X1 pins with LCD RGB data. Does that mean these slave select signals are not available if RGB data are used? There are no alternate pins for RGB data, right?
- There are no additional slave select signals for ecspi3 controller. Right?
- Over all in total only 2 SPI slave devices can be accessed each by an SPI controller (ecspi1 or ecspi3) when RGB data are used. Right?
