Hello,
I need to connect a 100M network chip and DM6467T, I want to realize it in u-boot first. The version of my u-boot that works ok on 1000M is 1.2.0.
According to the user guide of EMAC of DM6467, GMIIEN bit in MACCONTROL register is not set, however, I can't execute successfully "ping" in u-boot but the PHY is linked by mdio_read, the other setting is the same with 1000M model. In addtion, when 1000M network is detected, emac_gigabit_enable() is called to enable gigabit, taht is
adap_emac->MACCONTROL |= EMAC_MACCONTROL_GIGFORCE | EMAC_MACCONTROL_GIGABIT_ENABLE;
bit17 and bit7 of MACCONTROL is set, but bit17 and bit7 is reserved in user guide.
Is there something I ignored? Please give me some details, THX.
