Hi, 

I am using the eflash utility.

eflash.exe  -m 00:04:A5:80:05:45 -i 10.-:64.-:16.-:181 --verbose typhoon.bin  to flash the firmware for Typhoon over ethernet.

but on running the utility , it continues to send the Magic packets....

Starting WINSOCK
Starting BOOTP/TFTP Server ...
% Complete: 0%
Reading file (typhoon.bin) to be downloaded

... Reading the file

SnapShot on ethereal looks like  

as per TIVA Document  SW-TM4C-TOOLS-UG-20 , Ethernet bootloader is required for updating the firmware by ethernet .

Does the TIVA bootloader automatically loads the ethernet bootloader on boot up ?

or do we have to program ethernet bootloader separately ?

Thanks

    Hi, 

    Does TIVA C Series : Tiva™ TM4C1294NCPDT Microcontroller

    Does this support an API  " ROM_UpdateEMAC" for updating the firmware over the ethernet.

    I cannot find this API in EMAC.h library .

    Please help !

    Thanks,
