While trying to run the HTTP_Demo program included with the RL-ARM product, the following command:
gets no response from the MCBSTR9 board (or whatever board you use) and the HTTP_Demo server does not respond.
This problem occurs only if you use DHCP. If you disable DHCP in the HTTP_Demo and manually configure a Local IP Address, Subnet Mask, and Default Gateway IP Address, everything works.
Older HTTP_Demo configurations used an initial local IP address of 192.168.0.100 when DHCP was used. The local IP address should have been 0.0.0.0. This has been corrected in subsequent configurations.
If the local IP address configured in the HTTP_Demo matches the subnet address of your local network, DHCP will fail. For example, if your local subnet is 192.168.0.* and the local IP address in Net_Config.c for the HTTP_Demo program is 192.168.0.100, the DHCP server will not return an IP Address.
Change the Local IP Address in Net_Config.c to 0.0.0.0. Then, the DHCP server will assign the Local IP Address, etc. normally.
