    Hi,

    User can define their function in RAM.  An example how to define functions in RAM.

    __attribute__((section(".TI.ramfunc"))) __attribute__((noinline)) void appfunctions(void){}

    Best regards,

    Hi,
    customer want to run completely from RAM. So it makes more sense to move all section from FLASH to RAM. Right?

     .intvecs:   > 0x00000000
        .text   : palign(8) {} > FLASH
        .const  : palign(8) {} > FLASH
        .cinit  : palign(8) {} > FLASH
        .pinit  : palign(8) {} > FLASH
        .rodata : palign(8) {} > FLASH
        .ARM.exidx    : palign(8) {} > FLASH
        .init_array   : palign(8) {} > FLASH
        .binit        : palign(8) {} > FLASH
        .TI.ramfunc   : load = FLASH, palign(8), run=SRAM, table(BINIT)

    Regards, Holger

    Hi,

    Emm, all the sections defined into SRAM. I think it should work but I never tried this before.
