I have downloaded FreeRTOSV4.1.2 and even 4.1.1 and keep experiencing the same error, with IAR 4.30A (Using Kickstart4.0) gives the same error message when first opening the project:



Broken Links Detected

A backup copy will be made



Here are the error messages:



LOAD: Configuration 'Flash Debug' in the project 'rtosdemo' contains broken options for tool 'XLINK':

The format of this file is not supported by this version of the workbench. It appears to have been written by a newer version of the workbench.

I have built a couple of the other projects just to check IAR and all build OK. Any light you can shine would be greatly appreciated.

Please download the latest version (4.40A?) from IAR - the KickStart is a free download.

The project file format seems to change with annoying regularity. You will probably have to install a clean version of FreeRTOS.org from the zip file download also. Using an older version of Embedded Workbench to open a project created from a newer version has in the past resulted in the project being clobbered - with all options being lost.

Let us know if this fixes the issue.

Hi,

I compile uIP with gcc and i enable the UIP_LOGGING for debugging with serial port.

When i connect to my board with ethernet cable, i receive the follow error:

"ip: invalid version or header length"

Why? Can you help me please?

Thanks!

I suspect the structure packing is not correct. You have to use __attribute__ ((packed)). There was a post on the uIP mail list about this about a week ago you might want to look it up.
