Embedded Development Tools

I have been working SDK C project, one day all the C projects stop working.

I have ise 13.2 and implement my design on ML510 board.  I have some C project that talk to the Ethernet port written by other engineer (I am a beginner using SDK and writing C code to tell pc440 processor). The code was doing fine and yesterday I re-ran the C code, all the sudden it stops working. The LED is not on the board, I don’t see anything coming out from the UART. I tried to make a new hello world.c and copied my old code to my the helloworld.c , but it is still not working. Have it happen to you, I submitted a case on Xilinx, but the engineer did not give me any solution.

Thanks a lot

Have u tried after creating a fresh project?

I did try create a new workspace, I start a new C project, HelloWorld.c and it works fine, then I created another project IwIP Echo Server project. I assume the IwIP would work without any editting like the helloworld. But it is not working, I don't see anything that is coming out from the UART. I may try to create a fresh ISE project later today.

Thanks for the reply!

Is there any wrong message when you build the project,or everything is ok but it didn't work?Maybe you should make sure your usrt port on your pc is working fine and then right-click the elf file select "run as" then select "run configurations"  at the run configuration dialogbox select "STDIO Connection" page ,makesure you have "Connect STDIO to Console" option selected and right UART port selected in the listbox and have the right BAUD rate set.

Good luck!

For LWIP problem did u choose Xilkernel as your os?have u set it propoerly?

Look at the signals and the MHS file to see if you are using the TEMAC in MII mode.  If you are then you need to

be running at 100 Mb/s.  If you want to run at GB/s then you need to change the TEMAC to RGMII.

Thanks for the reply!

I am new bie to the EDK and SDK. Can you please show me how to choose Xilkernel as OS.

All the EDK and SDK project are setup by other eengineer, my job is writting PID loop in C/VHDL code and run it on the ML510.

I think I have the right UART port setup, if I make a C project helloworld.c in the same SDK project, I did get something out of it.

I mean look at your ethernet setup in the MHS file.  to check if it is set up for MII. That is the default setup.  If you want to

use Gigabit you need to change it to RGMII.
