rt ver: rt thread 4.0.1

在main.c 中
void dump_clock(void)
{
 rt_kprintf("OSC clock : %d ", CLOCK_GetFreq(kCLOCK_OscClk));
 rt_kprintf("RTC clock : %d ", CLOCK_GetFreq(kCLOCK_RtcClk));
 rt_kprintf("CPU clock: %d ", CLOCK_GetFreq(kCLOCK_CpuClk)); 
 rt_kprintf("AHB clock : %d ", CLOCK_GetFreq(kCLOCK_AhbClk)); 
 rt_kprintf("SEMC clock : %d ", CLOCK_GetFreq(kCLOCK_SemcClk)); 
 rt_kprintf("IPG clock : %d ", CLOCK_GetFreq(kCLOCK_IpgClk));
 rt_kprintf("SYSPLLCLK(PLL2/528_PLL) : %d ", CLOCK_GetFreq(kCLOCK_SysPllClk));
 rt_kprintf("SYSPLLPDF0CLK : %d ", CLOCK_GetFreq(kCLOCK_SysPllPfd0Clk));
 rt_kprintf("SYSPLLPFD1CLK : %d ", CLOCK_GetFreq(kCLOCK_SysPllPfd1Clk));

 rt_kprintf("USB1PLLPDF0CLK : %d ", CLOCK_GetFreq(kCLOCK_Usb1PllPfd0Clk));
 rt_kprintf("USB1PLLPFD1CLK : %d ", CLOCK_GetFreq(kCLOCK_Usb1PllPfd1Clk));

 rt_kprintf("Enet PLLCLK ref_enetpll : %d ", CLOCK_GetFreq(kCLOCK_EnetPllClk));
}

编译报错：

compiling main.c...
applications\main.c(44): error: #20: identifier "kCLOCK_EnetPllClk" is undefined
 rt_kprintf("Enet PLLCLK ref_enetpll : %d ", CLOCK_GetFreq(kCLOCK_EnetPllClk));
applications\main.c: 0 warnings, 1 error

请问，如何处理
