Hello, We are struggling with UART issue, I hope someone have any idea how to handle it. We have several UARTs on our device, after having this issue we updated the IP from simple UART IP to FIFO...

Hi,

Thanks for the links, it help understanding some stuff.

I see that the 1st link is using UART RS-232 IP, which has only 1 sample , i.e. no FIFO (!)

It also use baud 115200 in the software example.

From this I wander if this IP can ever be functional in high rates of 921600 bytes. Probably, the answer is - No...

I did find a non-Intel IP which has FIFO and is functional (after fixing bugs in the IP........)

Yet, I wander how it is that Intel does not have any functional FIFO UART.

Thanks,
