    First time programming a ARM/DSP chip. Got a OMAP-L138 EVM development Kit from a college and am trying get some of the basic stuff from the users Guide working.

    I get the following when trying to connect to the OMAP-L138.

    C674X_0: Error connecting to the target: (Error -1180 @ 0x0) Device is held in reset. Take the device out of reset, and retry the operation. (Emulation package 5.1.507.0)

    Tried reflashing with the instructions found here:

    http://processors.wiki.ti...d_Boot_Utils_Package

    This seemed to flash the chip and returned no errors but still getting the same error message when i try to connect with CCS.

    Any help would be appreciated.

    The end goal is to make a simple TCPIP client, but i need to be able to connect to the board first.

    Adam,

    If you are trying to reflash back to factory defaults, the link you provided is only a way to recompile the tools and it doesn't quite get what you want done. I would suggest looking through our document here: http://support.logicpd.co...rtalid=0&EntryId=778 about SPI Flash Recovery. The document has some pre-compiled binaries, instructions and tools for flashing the SPI with u-boot, and linux, etc.

    If you're trying to use a debugger with CCS, I would suggest looking at our document: http://support.logicpd.co...rtalid=0&EntryId=776 which describes how to use CCS with our SOM.

    In order to access these files, you'll need to register your SOM here: http://support.logicpd.co...RegisterProduct.aspx and that will unlock access to all the L138 files located here: http://support.logicpd.co...L138SOM-M1(EVM).aspx

    Does that help point you in the right direction?

    Yes. Thank you.

    Would you also have a recomendation of a place to look for how to setup a simple TCP/IP client on the board?

    Our primary source of documentation, examples, and files for this board are located here: http://support.logicpd.co...L138SOM-M1(EVM).aspx

    If you have previously erased your flash, I would suggest looking at http://support.logicpd.co...rtalid=0&EntryId=778 and the Section 6: Restore Ethernet MAC Address. Without a correct MAC address, none of the networking features will work.

    Our stock images run Linux and it has a variety of clients that use TCP/IP. Our virtual machine is located here: http://support.logicpd.co...rtalid=0&EntryId=988

    Under Linux, the Ethernet drivers can be initialized and the TCP/IP stack is available. The Linux user guide is located here: http://support.logicpd.co...talid=0&EntryId=1424

    Without knowing what you want/need to do, I am not sure how much help I can provide, if you let me know what you are trying to do I might be able to provide more assistance. Make sure you are logged in when try to click on the links or they won't work.

    So board has been reflashed, and MAC reprogrammed. I will look around at some of the linux stuff to see if it fits what i'm trying to do.

    The end goal is to have a TCP client (preferably in c) that parses text commands and then will send ?serial bus? commands to another piece of HW (don't have details on the other end of the interface just yet, want to get the TCP portion working first).
