TM4C1294NCPDT: TM4C1294NCPDT : Update via Ethernet - eflash stays at 0%

Part Number: TM4C1294NCPDT

Hello,

I imported lwip_enet project and added the sw update via ethernet. 

Upon running, I have a stable ping to 192.168.0.2 

Then, in the PC side I ran:

c:\ti\TivaWare_C_Series-2.2.0.295\tools\bin>eflash --ip=192.168.0.2 --mac=00-1a-b6-02-92-99 d:\module\WPINE\crc32.bin

I got:

Starting BOOTP/TFTP Server ...
% Complete:   0%

There is only one ethernet adapter which is active. All other are disabled. 

I double checked the MAC address of the TIVA. 

In Wireshark there are UDP broadcast messages sent to the TIVA. But there is not response. 

1    0.000000    192.168.0.1    255.255.255.255    UDP    72    62547 → 9  Len=30

2    0.509731    192.168.0.1    255.255.255.255    UDP    72    62547 → 9  Len=30

.....

Upon eflash start, I checked that g_bFirmwareUpdate is set to true and SoftwareUpdateBegin is called. 

The project contains also swupdate.c without any modifications. 

Can you please advise ?

Thank you,

Zvi
