FreeRTOS+TCP restart with new static ip ...

Posted by debugasm on July 28, 2017


Today I finally got to try FreeRTOS+TCP using MicroBlaze and EthernetLite on Spartan6 FPGA.

I am very happy because in my next project I want to use FreeRTOS+TCP instead of lwip.

I still have to do many tests and write a lot of code but I think that FreeRTOS+TCP will give me a lot of satisfaction, thanks to the excellent work that has been done up to here from the "Real Time Engineers ltd".

In my appliances I always use a static IP address, I do not use DHCP (which I have disabled) and for now I set the IP address hardcoded.

I have a problem though: How to change IP address when started FreeRTOS+TCP ?

I did not find any APIs for that, was not considered ?

I have found this :

~~~ FreeRTOSSetIPAddress FreeRTOSSetNetmask FreeRTOS_SetGatewayAddress ~~~

But missing :


But these routines do not seem appropriate to what I see in the code.

How do I change my network configuration after I have started FreeRTOS+TCP with another manually assigned IP address ?


While porting the EthernetLite driver I noticed that the call to:

BaseType_t xNetworkInterfaceInitialise( void )

does not pass the MAC address to be set to the EMAC interface, but it is necessary to refer to an external variable:

~~~ /* ucMACAddress as it appears in main.c */ extern const uint8_t ucMACAddress[ 6 ]; ~~~

Would not it be better to pass the MAC value as a parameter ?

There is an upgrade after "160919FreeRTOSLabs.zip" ?

Thanks so much.
