Hello,

if 

 i use EMAC_CONFIG_JUMBO_ENABLE in MACConfigSet along with

EMACPHYConfigSet(EMAC0_BASE, <config>);

// Initialize and configure the MAC.
EMACInit(EMAC0_BASE, <system clock rate>, <bus config>,
<Rx burst size>, <Tx burst size>, <desc skip>);


EMACConfigSet(EMAC0_BASE, <parameters>); can i send jumbo data or some other configurations is required.. I am using enet example as reference (lwiplibrary configuration ).

If some other things are required please replay........

Regards,

Krishnan

    Hello Kirshnan.

    That should be OK. But do make sure that the ethernet switch can handle a jumbo frame.
