At this point, your SDK workspace should contain only the hardware description and no applications:. The settings I need to check are in the Clock Manager: I hope this helps, Erich. With the network cable plugged in, the application writes the status to the semihosting console. It starts with a DHCP request and then does some IP broadcasts and at the end releases the address and closes the connection:.
I plan to post in the next weeks a few articles how I think it is possible to workaround the SDK.
You will find the modified library files inside the EmbeddedSw directory of the repo. A long-time-waiting thing on my to-do list finally has been accomplished: With the network cable plugged in, the application writes the status to the semihosting console.

Thanks for your reply Erich. Both computers have Windows Hi Yes I have this piece of code activated in main. But it is up to you.
Hi Matthew, yes, you can do this thing on Linux too. In your example the settings are in a spreadsheet like format the current version has tabs and windows and the setting tuotrial are not the same or missing. Say, getting images from camera modules connected via ethernet and image processing is done in the FPGA?
I recommend that you use the board first with a dedicated small network e.
