TMS570LC4357: Ethernet Bootloader example

Part Number: TMS570LC4357
Other Parts Discussed in Thread: TMS570LS1227, HALCOGEN

Hi,

 

I am trying to develop an ethernet bootloader for a different part, TMS570Ls1227, starting from a launchpad incorporating TMS570Lc4357.

 

I am currently stuck in trying to make the exmaple work, os far I:

The first time CCS 12 didnt recognize the folders so I had to adjust manually both the Boot, lwip1.4.1 and HALcogen folder paths.

Then whenever I tired building the example i was getting an error like gmake - nothing to build; for this I created a ew project, importing the needed folders and setting the sae parameters in the project config, such as variables and incude options.

 

I am still stuck in building the example, which is frustrating given that it should be an exmaple so I would expect not to be so a quest to make it work; so far I have the following issues:

 

  • fsdata.c throws me an incomplete type error
  • image.png
  • then it tells me fsdata.c is missing reference file <dir.h>, which I honestly don't have a clue where to find
  • image.png
  •  
  • finally lwip_check.h is missing reference file to "check.h" which I don't see anywhere

Can someone:

  • point me a working example, even a simple complete project which can be built so I can start looking at how it works etc
  • point me to what is actualy wrong or I am doing wrong, because I cannot understand how to make it work
  • if porting then the example to a different micro should be difficult, considering that the PHY used is a DP83848 instead DP838640?

thanks

    Hi Alberto,

    Apologies for the delayed response!

    My suggestion is that, instead of copying folders of ethernet example to your application folder, you can do modify in example application itself. I mean take that working ethernet example for TMS570LC4357 and then try below steps.

    1. First change the device from below location:

    2. If needed change debug connection as well.

    3. And then make pinmux changes to this example if your custom board is not as per the TI-specific board.

    After above steps the example should work on your TMS570Ls1227 as well. First try to test example as it is on your board before including more application changes.
