CC1101初始化问题

Other Parts Discussed in Thread: CC1101, CC430F6137

您好,我在初始化cc1101时,CS从高拉低时,应该SO会有个高电平的过程,但我在调试时候,SO管脚永远都是低电平,用示波器观测也没有信号,查阅手册,

When CSn is pulled low, the MCU must wait until CC1101 SO pin goes low before starting to transfer the header byte. This indicates that the crystal is running. Unless the chip was in the SLEEP or XOFF states, the SO pin will always go low immediately after taking CSn low.
我用示波器检查晶振是否起振,晶振也不起振,怀疑是焊接问题,重新补焊,新焊了一套板子依然如此,请问这个问题该怎么解决呢,使用的是STM32内部SPI,也怀疑过SPI初始化有问题,所以根据手册画的时序图重新改过 还是如此,把SPI初始化的几种可能都试了一遍,发现一直通信不上,读取到的寄存器数值永远是0.

晶振选用26M,20ppm的,起振电容27pf,也试过5pf的,都不行
