Part Number: TMDSIDK437X
Other Parts Discussed in Thread: AM4377

Hi, I'm trying to run AM4377 board(customed from IDK_AM437X) without DDR RAM.

I found the documentation(SPRAC45), but it makes me curious.

First, where's the file named 'ecat_appl_modif_QSPI_XIP.xdt'?

I searched whole hard drives, but that file doesn't appears.

And, how can I run application on OCMCRAM? Is there related GEL file or platform?

I want to run flash writing application without DDR....

Please anser these questions..

Thank you.

    Hi, after checking DDR-less application note, it is not clear from where to get ecat_appl_modif_QSPI_XIP.xdt, sorry about that, what we meant is that users can modify xdt using changes on 4.2.2 (third bullet). We will change the document in order to clarify this. Thanks for pointing it out.


    If you want to run from OCMCRAM, please follow instructions for "L3 build" through the document. Mainly, on top of my head, what you need to modify is your platform definition, CCS configuration file and GEL file if running  via JTAG or Bootloader. Below example of gel file addition for your reference:


    hotmenu ConfigureL2AsSRAM()

     {

                    *((unsigned int*) 0x44E10654) = 4;

                     *((unsigned int*) 0x44E101E0) =  0x10000 ; }

    Thank you,

    Paula
