Hi

     See attached pic snapped from 1020 reference manual.

     GPIO_AD_B0_04 has to work as JTAG_TDO and ENET_MDIO at the same time since 100pin 1021 does not have GPIO_EMC_40 & GPIO_SD_B0_02?

    if so, what if signals transmit on JTAG and ENET at the same time?

    OR does this means that i can only use swd to debug when enet used?

    please help. thks.
