Part Number:AM3358

In AM335x Starter kit, the 25MHz clock out of EMAC1-PHY is connected to XTLI of EMAC2-PHY.

However, on customer’s board, they used 2 separate crystals without connecting EMAC1-PHY to XTLI of EMAC2-PHY.

Would Switch mode still work?

Customer is seeing instability, where it disconnects within a few minutes.
