Hi,
To build u-boot-spl I had to put ps7_init.c and ps7_init.h in
/board/xilinx/zynq.
Then when I compile I get boot.bin in the TOPDIR.
The functions defined in ps7_init.* are called in spl.c.
For debug purpose I wanted put some xil-printf statements in my
ps7_init files. But it does not work, says ;
undefined reference to xil_printf
I included xil-printf.h in the ps7_init.c file, now it is unable to
locate this file.
I can find this file somewhere else and copy paset here, but I think
then it would complain about other missing files and parameters.
So how do I use printf statements in ps7_init.c file correctly.
such as this:
// Get the PS_VERSION on run time
unsigned long si_ver = ps7GetSiliconVersion ();
xil_printf ("\n ps7 Silicon Version : %d.0", si_ver);
If xil_printf is not valid here, then is there any other method to
display messages such as prointing si_ver wrt above snippet?
Thanks,.
Heshsham

You should use just printf or puts which are standard u-boot method
how to print something on console.
I have never debug that but you have to ensure that you can use console
at that time.
I would say that MIO setting for console has to be done.
Or you have second option which I haven't tried which is to use DCC port
where I believe you don't need to setup any MIO pin.
Thanks,
Michal
