Hi All,
I am using ARM v8-A Foundation Platform to debug my code. According to user guide, the base address of UART0 in system is 0x1c090000, so I use the following code to try to print a char via UART0:
*(volatile unsigned char *)(0x1c09000 + offset_of_tx_fifo) = ''a'; /* this code works in a real hardware */
But I see nothing in the command shell, in which I can see the result of printf(...) function
So my question is: can my code work in Foundation Platform?
Thanks.

Hi moonlight,
isn't there UART setting to specify the FIFO threshold? You should better set the threshold.
