C2000 LaunchPad - Linker Command File

Thanks for the infoTrey,

I need more help to get this application to run from Flash. Here is what I have.

I started by modifying the Example F2802X LaunchPad Demo (removed a few items not necessary for my app) and added a simple "blind a LED" loop in the main program. When I build this project with the 2802_RAM_lnk.cmd  it runs from RAM with the debugger. I have tried multiple linker command files including F2802x_Header_nonBIOS.cmd  (can't find DSP2802x_Header_nonBIOS.cmd) and can't get it to build and run from Flash. I am doing something fundamentally wrong in ccsV6 or with my app.

Here is the .C file:

//###########################################################################

// FILE:    PlasmaX.c
//
// TITLE:   This is a modified example from C2000 LaunchPad
//
// ASSUMPTIONS:
//
//    This program requires the F2802x0 header files.
//
//    This program makes use of variables stored in OTP during factory
//    test on 2802x TMS devices only.
//    These OTP locations on pre-TMS devices may not be populated.
//    Ensure that the following memory locations in TI OTP are populated
//    (not 0xFFFF) before use:
//
//    0x3D7E90 to 0x3D7EA4
//
//    As supplied, this project is configured for "boot to SARAM"
//    operation.  The 2802x Boot Mode table is shown below.
//
//    $Boot_Table
//    While an emulator is connected to your device, the TRSTn pin = 1,
//    which sets the device into EMU_BOOT boot mode. In this mode, the
//    peripheral boot modes are as follows:
//
//      Boot Mode:   EMU_KEY        EMU_BMODE
//                   (0xD00)         (0xD01)
//      ---------------------------------------
//      Wait         !=0x55AA        X
//      I/O           0x55AA          0x0000
//      SCI          0x55AA          0x0001

//      Get_Mode     0x55AA          0x0003
//      SPI          0x55AA          0x0004
//      I2C          0x55AA          0x0005
//      OTP          0x55AA          0x0006
//      Wait         0x55AA          0x0007

//      Flash        0x55AA          0x000B
//      Wait         0x55AA          Other
//
//   Write EMU_KEY to 0xD00 and EMU_BMODE to 0xD01 via the debugger
//   according to the Boot Mode Table above. Build/Load project,
//   Reset the device, and Run example

Would appreciate your thoughts.

Hello John,

Maybe this picture below can help you. I forgot which thread I put this picture so I put it directly for you here.

And now the ControlSuite has new version (I think it should be v220 or more for F2802x). In the picture it mentioned v210, better you use the ones from the latest version.

Best regards,

Maria

Thanks Maria,

I'll give it a try.

Cheers, John
