Second SPI requirement is solved only by using ECSPI2 pins. But I’ve just seen a note in the Verdin iMX8 Plus Datasheet that Pin 116 and 128 which are ECSPI2_MISO and CS are also connected to AW-CM276NF WiFi module’s pin 46 and 28. Does that mean, ECSPI2 cannot be used for my own peripheral?
Thank you for the reply. As you can see on the image, unfortunately all alternative pins you mentioned are yellow (means already occupied for others). What we need in the project is 4 UART, 2 SPI Master, 1 QSPI Master, 3 I2C. Having such system looks like possible in the Pinout Designer (0 conflict), but it seems in reality it is not. Please see the project.xml for the Pinout Designer that I uploaded below.
Hi Fide, your project still shows some conflicts. What is your actual HW requirements? Can you connect all your I2C devices to one I2C line? If you don’t need a parallel access to your SPI devices you can utilize only one SPI channel and select current device (CS) by any available GPIO line.
