Hi,
I'm currently working on bringing life to our custom mpc8572 board. Its equipped with;
- 2 GB ram - 64 MB NOR - 1 GB Nand - TSEC1 connected to single phy with fiber optic transceiver ( use MDIO channel 1 ) - TSEC2,3 & 4 connected to a marvell 81145 quad phy ( use MDIO channel 3 ) - 2 virtex6 connected to each pcie 4x lane
At this moment, the Nand and Nor seems ok. I have flashed the Nor via bdi3000 and u-boot prints out its prompt.
To be able to discover the phy, I had to hardcode the tsec.h to use MDIO offset 0x2600 instead of 0x2400. The phy's are now detected, but there seems to be some problem with the data part.. I'll need to measure some freqs.
Nevertheless, is there some other proper way of configuring MDIO 3 as main MII interface ? Is it enough to:
mycard.h
#define CONFIG_SYS_MDIO3_OFFSET 0x26000
#define TSEC1_MDIO_ADDR ( CONFIG_SYS_IMMR + CONFIG_SYS_MDIO1_OFFSET ) #define TSEC2_MDIO_ADDR ( CONFIG_SYS_IMMR + CONFIG_SYS_MDIO3_OFFSET ) #define TSEC3_MDIO_ADDR ( CONFIG_SYS_IMMR + CONFIG_SYS_MDIO3_OFFSET ) #define TSEC4_MDIO_ADDR ( CONFIG_SYS_IMMR + CONFIG_SYS_MDIO3_OFFSET )
#define TSEC1_PHY_ADDR 0 #define TSEC2_PHY_ADDR 2 #define TSEC3_PHY_ADDR 3 #define TSEC4_PHY_ADDR 1
#define TSEC1_FLAGS ( TSEC_GIGABIT | TSEC_REDUCED | TSEC_FIBER ) #define TSEC2_FLAGS ( TSEC_GIGABIT | TSEC_SGMII ) #define TSEC3_FLAGS ( TSEC_GIGABIT | TSEC_SGMII ) #define TSEC4_FLAGS ( TSEC_GIGABIT | TSEC_SGMII )
tsec.h
#define SET_STD_TSEC_INFO(x, num) \ { \ x.regs = (tsec_t *)(TSEC_BASE_ADDR + ((num - 1) * TSEC_SIZE)); \ x.miiregs = (tsec_mdio_t *)(TSEC##num##_MDIO_ADDR); \ x.miiregs_sgmii = (tsec_mdio_t *)(TSEC##num##_MDIO_ADDR \ + (num - 1) * TSEC_MDIO_OFFSET); \ x.devname = CONFIG_TSEC##num##_NAME; \ x.phyaddr = TSEC##num##_PHY_ADDR; \ x.flags = TSEC##num##_FLAGS;\ }
Best regards
