CCS/TMS570LC4357: ethernet(eMAC) communication with PC

Mu He
Prodigy 10 points
Part Number: TMS570LC4357


Tool/software: Code Composer Studio

I am using the tms570lc43x launch pad and I can run the LWIP demo on TI wiki page. Now I want to use the launch to sample and process signals and then use the ethernet (eMAC)  to send the data from development board to my laptop.  From the demo, what part should I continue modifying?

Or if I want to link laptop and launch pad direct by an ethernet cable, how to send the data to my laptop?

Hope someone who has similar experience could help me out!

Thanks very much!

    Hello Mu He,

    There's a good example if you look at the ethernet bootloader for Hercules MCU. The bootloader uses the TFTP protocol for uploading file to the device. The TFTP protocol uses UDP provided by lwIP. You should be able to follow the function calls from tftp.c through lwIP to the ethernet driver.
