I'm a newbie to Zedboard,and now I have met some problems, but I don't know what's wrong . I have tried to move linux on Zedboard, and I have followed the tutorial on Zedboard.org support-Reference Designs/Tutorials-Ubuntu Desktop Linux.
Now, my board can start Linux with HDMI signal out .That's what I want .And common orders like rm,ls etc also wokrs well. But when I wrote a program to test , something wrong happened.
I have written a simple program that just used a printf .I used the cross comoiler arm-xilinx-linux-gnueabi-gcc to compile it in the VMware,and then I put it into the Zedboard. But when I ran this program on the board, I didn't see any messages that should printed by the printf in the terminal. Also,there is no messages to show that the program is wrong. The program is just run ,and printf nothing. I have no idea what's wrong with it, so I wrote another program which used fprintf to write "hello world" into an empty txt file. I also use cross compiler to compile it ,and ran it on the board. This time , after running, I saw nothing in the empty txt file,and I think the program may just not run at all.
by the way ,all the functions of the two programs were tested to be right.
so I want to know what's wrong with it ?maybe the file uImage is lack of some function? or there are some other questions?
Thanks in advance.
