Describe you problem
如下图所示,uart_16550的axi clock frequency最低支持到25Mhz。但是我也成功跑通了xiangshan 10M的bitfile,我想了解是怎么修改的uart_16550才能够实现让其能够接收低于25M的主时钟?
As shown in the figure below, the minimum supported axi clock frequency of uart_16550 is 25Mhz. But I also successfully ran the xiangshan 10M bitfile. I want to know how to modify uart_16550 to enable it to receive the main clock below 25M?
