problem with uartlite in microblaze

[bhb]

Hi,

I 'm learning to use microblaze (microblaze, EDK 9.1 sp2).
I try to use the Send function of uartlite.
Please, find below my c code.
the result of this code (with hyperterminal) is :

-- Entering main() --
nXUartLite_Send
-- status true--
-- status true--
-- XUartLite_SendByte --
e
-- Exiting main() --

I never received the 'D' char (byte_buf = 0x44), and val.
Is someone could hep me.
thanks in advance
bhb.
