XPS Uartlite Baud Rate Anamoly

[traana]

I am using an xps_uartlite IP Peripheral(1.02.a) for Uart Communication. I have set the baud rate in the EDK as 9600. But when i check the data at the receiving end , i am able to receive it only at half the baud rate as the transmitter side (i.e. 9600/2 = 4800). I have varied the baud rates and the above applies to all. I tried probing the TX Port on the FPGA through Chipscope debug peripheral and i ensured myself that the data coming out was at the set baud rate.

i am using a Spartan 3a-DSP with 50 Mhz Clock.

Is  this a known issue. Please assist me with this as early as possible.

I'm getting a similar issue, and it also affects UART16550. I suspect it's an FSBL issue, but I can't boot from any that I generate.

Found that I needed to add the DDR to the FSBL, and once that boots, it works at normal baud.

Incorrectly setting the FSBL or incorrectly setting the device tree will cause this to happen.
