器件型号：AFE7920EVM 大家好、
我已经尝试修改了随 AFE7920EVM Latte 软件提供的中继器脚本(#5)、以便其 PLL 从外部时钟源(@163.68MHz)以分布式模式工作。
代码(随附的)可用于编译和运行、但也会报告以下错误：
器件 DAC JESD-RX 0链路状态
通道0：1的 SerDes-FIFO 错误
CS 状态 TX0：0b00001010。 预计为0b00001010
FS 状态 TX0：0b00000101。 预计为0b00000101
无法获取设备 RX：0的链接；警报：0x1000
器件 DAC JESD-RX 1链路状态
通道1的 SerDes-FIFO 错误：1.
CS 状态 TX0：0b00001010。 预计为0b00001010
FS 状态 TX0：0b00000101。 预计为0b00000101
无法为设备 RX：1获取链接；警报：0x2000
我怀疑这些错误来自以下事实：我没有修改任何 JESD204B 接口属性、因为它们仅取自原始中继器脚本。
但是、我不太确定这些错误的确切原因是什么。 您是否可能对我修改的设置中可能出现的问题有任何看法？
非常感谢您的参与、
Zeljko
