Hi team,

Here's an issue from the customer may need your help:

When using LAUNCHXL-F280049C eva. board, the customer has tried to running the led_ex1_blinky demo code in flash and in eabi style .so I changed f28004x_usdelay.asm and rebuild it.

    Hi Cherry,

    Which version of C2000ware SDK the customer is using? 

    I will suggest the customer to install latest C2000Ware SDK (4.00.00.00).

    Import the blinky_LED example from DriverLib example (C:/ti/c2000/C2000Ware_4_00_00_00/driverlib/f28004x/examples/led) and then select CPU1_LAUNCHXL_FLASH build configuration. It will be in EBI format and it should work out of the box.
