5.1.A E1 Board Modifications

  1. OSPI Modification - Implemented to all E1 boards out-of-box.

    The initial design of the AM263Px Control Card E1 included a 2.5 inch stub hanging off of the OSPI DQ0 and DQ1 signal lines. These stubs lead to unreliable use of the OSPI peripheral. Below is a list of the modifications that were carried out on all E1 versions of the Control Card.

    • Cut the OSPI DQ0 and DQ1 traces on the outside of the vias next to the termination resistors and the mux.
    • Solder a blue wire from R91 to U80 pin 4.
    • Solder a blue wire from R90 to U80 pin 3.
    • Solder one side of the 10kΩ resistor to each of the blue wires added above.
    • Remove R122 and R119.
    • Add blue wire from R91 bluewire 10kΩ resistor to R122 pad closest to U48.
    • Add blue wire from R90 bluewire 10kΩ resistor to R119 pad closest to U48.
  2. CPSW Ethernet Modification - Must be implemented by the user.
Note: This modification was not done to the E1 boards.
Note: This does not apply to E2 versions of the board and beyond.
Note: The board has the PRU0 MII0 signals routed by default to enable CPSW RGMII2. The following modifications need to be followed
Note: The MCAN transceiver and on-board Ethernet cannot be used simultaneously on the E1 version of the AM263Px Control Card.

The E1 AM263Px Control Card had a blue-wire fix to enable the CPSW RGMII2 Gigabit ethernet port with the associated MDIO. The changes are listed below:

  • Routing MDIO0_MDIO to the on-board Ethernet PHY:
    • Remove R208 and solder wire from exposed pad that is not connected to L17 of the SoC to HSEC pin 96.
  • Routing MDIO0_MDC to the on-board Ethernet PHY:
    • Remove R466 and solder wire from R466 pad tied to MCAN1_STB signal.
    • Remove R211 and solder the other end of the MCAN1_STB wire to the R211 exposed pad that is not connected to L18 of the SoC.
  • TCAN1043 Enable driven low
    • Since MCAN1_STB is now routed for MDIO0_MDC, the MCAN transceiver needs to be disabled to avoid any leakage current along the MCAN1_STB trace.
