Unexpected OUI number of TJA1100

[quocvietvu]

Hi supporter,

I'm doing integration Ethernet stack on TJA1100 Ethernet daughter card.

I tried to read the PHY Identifier and it returns as below:

It is unusual because as I know OUI of NXP is 0x6037.

The daughter card I'm using is has some labels "700-29797 REV B2", "SCH-28=9797 REV B4"

Can you please to check this issue?

Best regards,

Viet

I fixed this issue. It is caused by the clock too fast.
