    Hi Valery

    Most of these do look like valid inconsistencies. Thanks to your customer for pointing them out.

    We need to get those fixed (if not already getting fixed in upcoming revisions)

    Here is an updated table with confirmation on what should be the correct pin name etc

    I marked some as "No Issues" as I didn't see any discrepancy there, let me know if we missed something.

     

    NO. Pin Assignment Terminal Function Corrected
    U9 DDR_CAS DDR_CAS No Issue
    R4 DVDD3313_C DVDD3318_C DVDD3318_C 
    P12 DVSS3318_C DVDD3318_C DVDD3318_C
    G16 GP1[15] GP1[5] GP1[5] 
    E19 SPI1_SCS[0] SPI1_SCS[0] No Issue
    F9 EMA_CS[4] EMA_CS[4] No Issue
    E1 GP1[19] GP1[9] GP1[9] 
    E2 GP2[10] GP1[10] GP1[10]
