[参考译文] AFE7950：OSCIN = 100MHz 的 LMK 生成编译错误

https://e2e.ti.com/support/rf-microwave-group/rf-microwave/f/rf-microwave-forum/1234546/afe7950-lmk-with-oscin-100mhz-make-compile-error

尊敬的 TI：

我制作了一个可以接收 LMK OSCIN 外部参考的 ADC 板( PLL2参考输入)

对于 OSCIN 的输入122.88MHz 也是可以的。

但当我从122.88MHz 更改为100MHz 时

并缓冲修改的 Latte 启动脚本  ConfigLMK.py

它显示如下所示的错误

我查看 LMK04828数据表(第13页)

该图显示允许100MHz OSCIN

并且 VCO 可以支持高达3080MHz 的频率(第1页)

请帮助~

顺便说一下、我无法加载 Latte igui、  

有最新的拿铁版本吗?
