'C674x - SYS/BIOS Ethernet TCP/IP stack

Hello,

Is there an ethernet stack available in sysbios for the TMS320C674x devices?  If not, when?

Thanks!

    There actually is an OS-less software package that has a TCP/IP stack.

    Hi Brandon,

    First of all I'm a bit lost :}   We have developed a number of products using C6701/C6711/C6713/C6722 over the years using CCS3 and our own code to do interrupts/EDMA/Serial/Simple threading etc.  We now want to move to C6748 with Ethernet by initially using the C6748 SOM developed by LogicPD.   We have a TMDSEVML138-B for evaluation.  I had some early success with using CCS4, downloading the TCPIP Stack that runs under DSP/BIOS5.  The Client Demo Works and I was able to serve a web page and echo Socket data and test throughput.  All looked good.  But since then I've been spinning my wheels for two months.  I develop under MS Windows btw.  I've tried various combinations of CC4 and CC5,  DSP/BIOS5 and SYS/BIOS6, with the TCPIP Stack, and I can't find any tutorial or quickstart that matches my screens or versions that I can follow and get even the simplest example to work or allow me to modify it to do something like add in a timer task or interrupt. 

    Now there is this starterware-c6dsp approach.  It looks attractive to me as SYS/BIOS looks overly complicated and I worry I won't have enough low level control to meet my real-time microsecond deadlines.  I downloaded and imported the examples and they Build without errors.  But I can't run/debug them.  Maybe I don't have the right Target configuration.  Seems like XDS100V1 or 2 and TMS320C6748 should be correct and it "Tests" ok.  But the the code won't load.  The .cmd sets the code to load at 0xC0000000 which fails.  If I change the linker to put stuff in L2 internal memory instead of DDR2 memory the code loads, I can step through it, but it doesn't seem to work (DHCP fails and such).

    I apologize for the long-winded request.  But I would like some recommendation from TI to point me in a recommended direction.  We are fairly open as we are making a significant architecture change and want to go with the best set of tools that are currently available.

    Any help greatly appreciated and I can supply any other needed info on request and/or if I should post this somewhere else.

    Thanks
