你提到的问题似乎是-R问题。我建议您尝试将ECOTYTR寄存器设置更改为中高或最高振幅模式（参照寄存器设置AN2027）。这将增加设备的R，并确保设备正确启动。
最好的问候，
普什克

  The problem you have mentioned seems to be the -R problem. I suggest you to try changing the ECO_TR register setting to Medium HIGH or the HIGHEST amplitude mode (refer to AN2027 for register setting). This will increase -R of the device and will ensure that device does start properly.

XTAL振荡器是“棘手”的故障排除，XTAR参数的阻抗测量困难，因为Z的范围，探头看振荡器运行必须是超低C，因为你正在处理非常低的振荡器C值开始。为了克服这个问题，使用具有高灵敏度的范围，并且通过HI系列R或低C值从OSC节点解耦探针以最小地影响OSC。
XTAL振荡器通常工作在非常高的共振产生的值，容易受到任何“触摸”它们的影响。
谷歌“晶体振荡器基本应用说明”，大量的AP笔记。
特别注意的事实是，外部XTAL C比在XTAL和2个盖帽的有效传递函数中提供电压增益。
问候，Dana。



     以下为原文
  Xtal oscillators are “tricky” to troubleshoot, impedance measurements of Xtal parameters
difficult because of range of Z’s, probes to look at oscillator running have to be ultra
low C as you are dealing with very low oscillator C values to start with. To overcome this
problem use scopes with high sensitivity, and decouple probe from Osc nodes via Hi series
R or low  C values to minimally affect Osc.
   
Xtal oscillators typically operate at very hi Z resonant produced values, easily affected
by anything that “touches” them.
     
    Google “crystal oscillator basic application note”, lots of ap notes.
     
    Pay particular attention to the fact that external Xtal C ratios provide voltage gain in
the effective transfer function of the Xtal and the 2 caps.
