Hi~, I'm using LwIP in to ask questions about any problems that have occurred.
Icludes the following topics:
1. Environment
RM48HDK
CCS 5.3.0
HALCoGen 03.05
SafeRTOS
2. Description
I got HALCoGen_EMAC_Driver_and_lwIP_Demonstration-000100.exe(HALCoGen+LwIP Demo for RM48) from website.

LwIP in this demo is standalone system and is set to DHCP. DHCP is running successfully. And then, I have changed NO_SYS(lwipopts.h) to 0 for using lwip under SafeRTOS on RM48HDK. As a result, the following error has occured.

These functions are only declared(lwip-1.3.2\src\include\lwip\sys.h) and not the source code(lwip-1.3.2\ports\hdk\sys_arch.c).
What is the way to solve this problem?
Can I get the necessary new sys_arch files?
Please help me~
Thanks.
