AT91RM9200 EMAC的MAC配置
||
配置SA1L和SA1H寄存器時(shí)，假如MAC地址是00:11:22:33:44:55，即At91EnetAddr[6]={0x00,0x11,0x22,0x33,0x44,0x55}，則正確的賦值方式是：
for (i = 0; i < 6; ++i) {
pDrvCtrl->enetAddr[i] = At91EnetAddr[i];
}
pEmac->EMAC_SA1L = ((int)At91EnetAddr[2] << 24) | ((int)At91EnetAddr[3] << 16) | ((int)At91EnetAddr[4] << 8) | At91EnetAddr[5];
pEmac->EMAC_SA1H = ((int)At91EnetAddr[0] << 8) | At91EnetAddr[1];
其中pDrvCtrl為指向EMAC控制結構AT91_DRV_CTRL的指針。
for (i = 0; i < 6; ++i) {
pDrvCtrl->enetAddr[i] = At91EnetAddr[i];
}
pEmac->EMAC_SA1L = ((int)At91EnetAddr[2] << 24) | ((int)At91EnetAddr[3] << 16) | ((int)At91EnetAddr[4] << 8) | At91EnetAddr[5];
pEmac->EMAC_SA1H = ((int)At91EnetAddr[0] << 8) | At91EnetAddr[1];
其中pDrvCtrl為指向EMAC控制結構AT91_DRV_CTRL的指針。
