10.1 EDK - "ERROR:MDT - ERROR FROM TCL:- lwip () - child process exited abnormally"

Description

I am using lwip 2.0. When I try to compile my design, the following errors occur:

"ERROR:MDT - Error while running "execs_generate" for processor ppc405_0...

ERROR:MDT - ERROR FROM TCL:- lwip () - child process exited abnormally

while executing

"exec bash -c "cd src;make all \"COMPILER_FLAGS=$compiler_flags\"

\"EXTRA_COMPILER_FLAGS=$extra_compiler_flags\" >& logs""

(procedure "::sw_lwip_v2_00_a::execs_generate" line 51)

invoked from within

"::sw_lwip_v2_00_a::execs_generate 39167188"

ERROR:MDT - Error while running "execs_generate" for processor ppc405_0..."

Solution

To trouble-shoot this issue, follow these steps:

1. Check whether the Ethernet used is supported with lwip. Supported MACs are listed in the document at the following location:

<edk_installation_directory_path>\sw\ThirdParty\sw_services\lwip_v2_00_a\doc\lwip_v2_00_a.pdf

2. Check whether the MAC address is correctly set; check the document referenced above.

3. Make sure a forward slash "/" is used instead of a backward slash "\".

4. Refer to (Xilinx Answer 21823) for a similar problem with the plb_ethernet.
