MX_ETH_Init() fails on MB1137 board.

[dungeonlords789]

Default firmware for MB1137 doesn't start. I use Cube IDE 1.8 with 1.16.2

MX_ETH_Init() fails firmware to Error_Handler().

Most probably it's because there is no ethernet cable connected at startup. I'm having the same issue with a NUCLEO-F439ZI board. Apparently this hasn't been fixed in years.

Also verify the PHY config data. In CubeMX view the ETH peripheral, then click on "Advanced parameters". I've had instances where the mask values were wrong for the LAN8742**. Specifically the status reg offset (0x1f), speed and duplex masks (0x0004 and 0x0010, respectively) and link down interrupt (0x0010).

** Looks like CubeMX 6.3.0 sets these incorrectly when starting with the NUCLEOF746 board
