[lwip-users] LWIP sys_init in MicroBlaze

[Jim Law]

Hi all,

 

We are trying to use the lwip stack in a Xilinx Microblaze system, with the Ethernet (not lite) MAC core and the Xilinx microkernel.  Using a NuHo S3-2000 development board and v7 Xilinx tools.  We've been trying to compile the example program given with the Xilinx EDK illustrating the lwip, but have found several errors (which we think we've caught), and are having a further problem:  The sys_init function seems not be available in the libraries.  Found some references that seem to imply that this is supposed to be automatically generated by the system build, but it never appears. 

 

Has anyone tried to run the Xilinx example? 

 

Does anyone have any thoughts on the missing sys_init?

 

Does anyone have a working sample of the use of the lwip stack with the Microblaze?

 

Does anyone have any guidance about the order of libraries to pass to the linker?

 

Any and all comments welcome and very much appreciated.
