Part Number: AM3352
when I use the default project NIMU_BasicExample_bbbAM335x_armExampleproject for my test,
I can't ping the device successful.
Through the code, we learned that the code related to the initialization of emac has the following parts:
/* Chip configuration MII/RMII selection */ SOCCtrlCpswPortMacModeSelect(1, ETHERNET_MAC_TYPE_RMII); SOCCtrlCpswPortMacModeSelect(0, ETHERNET_MAC_TYPE_RMII);
EMAC_socGetInitCfg(0, &cfg); cfg.port.phy_addr = EMAC_CPSW_PORT0_PHY_ADDR_EVM; cfg.port.phy_addr = EMAC_CPSW_PORT0_PHY_ADDR_EVM; cfg.macModeFlags = EMAC_CPSW_CONFIG_MODEFLG_FULLDUPLEX; EMAC_socSetInitCfg(0, &cfg);
/create app task/
NIMUDeviceTable[nimu_device_index++].init = &CpswEmacInit ; NIMUDeviceTable[nimu_device_index].init = NULL ;
about the soc,is there any config for HW except SOCCtrlCpswPortMacModeSelect?
and I know the init and register EMAC is by CpswEmacInit .
how can I know init and register EMAC success,is there any log?
I don't know how does CpswEmacInit function exectued.so I don't know if EMAC has init or register.
In reply to lding:
can you give me the link of TI BBB circuit design document,I will ask our HW engineer to check.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
