Summary0005347: Alternative pin for USB Type-C ALERT on J2_77 not available on PicoCoreMX8MM/Mx with i.MX8M-Nano
DescriptionThe USB Type-C ALERT pin is basically located on pin J3_15 on the extra 30-pin B2B-Connector J3. However J3 is not available on several PicoCore platforms. So in Rev 1.40, the alternative pin location J2_77 was added. J2_77 is defined as I2S_B_RXFS which is not very important. However this pin is also not available on PicoCoreMX8Mx when an i.MX8M-Nano is equipped, because it is implemented by CPU pad SAI1_RXFS and SAI1 does not exist on the Nano. On PicoCoreMX8MM with Nano, J2_77 is only available on CPU pad SAI2_RXFS if CAN is not equipped.
