## Summary STM32H5 Ethernet Driver. This driver is heavily based on the STM32H7 because the Ethernet peripheral on the STM32H5 is essentially identical to that on the STM32H7. Differences from the STM32H7: 1. stm32_uid.c - Reading the device electronic signature 8-bits at a time (like the H7) caused an exception. The code was modified to access the device electronic signature 32-bits at a time. 2. ETH_SEL_PHY - These bits are located in the SBS_PMCR register on the STM32H5. This is different on the STM32H7. This change also required enabling SBS peripheral when Ethernet is configured. Note: ICACHE and DCACHE not yet implemented on STM32H5. ## Impact STM32H5 Architecture ## Testing Hardware: 1. Nucleo-H563ZI 2. USB-to-Ethernet adapter (for test device) Software: 1. Ping 2. Phy Tool (mdio) 3. ifconfig Configuration: Use STM32H7 netnsh config as an example. Added network related options to standard nsh STM32H5 Nucleo-H563ZI config. Procedure: 1. Initialize the STM32H5 Ethernet device eth0. Configured IP address of 10.0.0.2. LAN8742 configuration done in menuconfig. 2. Run ifconfig on eth0. 3. Run a couple of MDIO commands to ensure proper functionality. 4. Ping the test device (IP = 10.0.0.5) Tested at 100Mb/s Half Duplex.
