Tool/software: TI-RTOS
Hi all,
When I use the EMACPHYRead() and EMACPHYWrite() on chip of TM4C1294NCPDT, I take a look at the physical address of the internal PHY.
#define PHY_PHYS_ADDR 1 in EMACSnow.c
#define EMAC_PHY_ADDR 0 in emac.h
There are in different software products in tirtos_tivac_2_16_01_14.
From the datasheet,
20.4.2.5 PHY Address
The integrated PHY's address is 0x00. To access the integrated PHY registers through the internal
MAC's MDIO interface, the PLA bit field of the Ethernet MAC MII Address (EMACMIIADDR) register
must be 0x00 and the MII field should be programmed to the desired address value.
Should I use physical address of the internal PHY in correct way?
