Q1) Because my project used and modified from demo\CORTEX\_LM3SxxxxIAR\_Keil sample, do I only need to replace the  demo\Common and Source, TraceCon from v5.0.3 to v5.2.0? Q2) Also since my project also used web server (uIP), do I have to replace the webserver sub-folder under the CORTEX\_LM3SxxxxIAR\_Keil? Regards, Bill Yang ---
