    hello sir,

               I am using the same example .

    First point is that nothing is printing on the tera term on pc. getting below message on console.

    C28xx_CPU1: GEL Output:
    Memory Map Initialization Complete
    C28xx_CPU1: If erase/program (E/P) operation is being done on one core, the other core should not execute from shared-RAM (SR) as they are used for the E/P code. Also, CPU1 will be halted to determine SR ownership for the CPU which will run the Flash Plugin code, after which CPU1 will be set to run its application. User code execution from SR could commence after both flash banks are programmed.
    C28xx_CPU2: GEL Output:

    Second Point , this example is not using the printf() function , they have taken the string and writing string first and then using function which is making code  not look good and printing it by sending from function to pc, i want to use the standard library printf for my application  because this

    Please help me with these problems.
