I'm having an issue getting Ethernet to work on STM32H743 Nucleo-144.  The issue seems to be a DMA bus error (see register values below).

 

dhcp_discover: sendto(DISCOVER, IP_ADDR_BROADCAST, DHCP_SERVER_PORT)
low_level_output(): HAL Tx status: 1 (err 8) (DMACSR 0x51002) (DMADSR 0x300)

 

The project was generated using CubeMX 4.24.0 and STM32H7 FW 1.2.0.

 

The linker file is attached.
