你好，我是用gel打开的EMAC的PRCM，但还是访问不了EMAC的寄存器（0x4A100000）
gel程序
emac_clkenable()
{
GEL_TextOut("CONFIGURE PRCM CLOCKS of EMAC in progress \n\r");
*((unsigned int*)(0x48181404)) = 0x2; //CM_ETHERNET_CLKSTCTRL Register
*((unsigned int*)(0x481815d4)) = 0x2; //CM_ALWON_ETHERNET_0_CLKCTRL Register
while(RD_MEM_32(0x48181404)!=0x0302);
while((RD_MEM_32(0x481815d4)&0x2)!=0x2);
GEL_TextOut("PRCM CLOCKS of EMAC is complete \n\r");
}
