[U-Boot] MPC8360ERDK U-Boot - Broadcom Gigabit Ethernet removal

[cmfairfa at rockwellcollins.com]

PS
The RX errors generated by switching from the Broadcom Ethernet chips to 
the National Ethernet chips are specifically RxBD_CRCERR and RxBD_NO 
(defined in uec.h).
These errors are frame CRC error and Non-octet align errors respectively.

Thanks.

MPC8360ERDK U-Boot - Broadcom Gigabit Ethernet removal





Hi,
I'm trying to completely remove the 2 gigabit ethernets from my U-Boot (as 
they are depopulated on my target). I want to use the other 2 ethernet 
ports as FSL UEC0 and FSL UEC1.
I've removed the UCC1 and UCC2 entries from the qe_iop_conf_tab in 
mpc8360erdk.c and updated the corresponding macros in MPC8360ERDK.h. The 
transmits seem to work. I'm able to communicate from the target to a TFTP 
server on a PC. However, the RX to the target is not working.
I get "FSL UEC: Rx error" messages.


Any ideas/suggestions as to what I need to do to get the RX to work?

Also, do I need to define CFG_CMD_MII  and/or CFG_MII, so that 
miiphy_register() is called in uec.c


Here are my new macro definitions in MPC8360ERDK.h:

#define CONFIG_UEC_ETH1 /* GETH1 */

#ifdef CONFIG_UEC_ETH1
#define CONFIG_SYS_UEC1_UCC_NUM  6      /* UCC7 */
#define CONFIG_SYS_UEC1_RX_CLK          QE_CLK19
#define CONFIG_SYS_UEC1_TX_CLK          QE_CLK20
#define CONIFG_SYS_UEC1_ETH_TYPE        FAST_ETH
#define CONFIG_SYS_UEC1_PHY_ADDR        1
#define CONFIG_SYS_UEC1_INTERFACE_MODE ENET_100_MII
#endif

#define CONFIG_UEC_ETH2 /* GETH2 */

#ifdef CONFIG_UEC_ETH2
#define CONFIG_SYS_UEC2_UCC_NUM  3      /* UCC4 */
#define CONFIG_SYS_UEC2_RX_CLK          QE_CLK7
#define CONFIG_SYS_UEC2_TX_CLK          QE_CLK8
#define CONIFG_SYS_UEC2_ETH_TYPE        FAST_ETH
#define CONFIG_SYS_UEC2_PHY_ADDR        3
#define CONFIG_SYS_UEC2_INTERFACE_MODE ENET_100_MII
#endif


Thanks
