Hi,

I don't have Tivaware 2.0 and IAR to be much help. Better wait for the TI forum members here to reply.

Your attached zip file contains bootloader files. Most probably that NMI happened at application code. In that case, what is needed is the application code to determine why it goes to NMI handler while debugging.

Leon,

I suggest to post your question in the internal forum to get support on this. There isn't ethernet bootloader example in TivaWare2.0 release for TM4C129X, but I am sure ethernet bootloader has been tested on this part, there should be a working version of the bootloader already exist.
