TMS570ls3137 linker file

do you have an example of how to setup the linker file to start at address:

APP_START_ADDRESS =  0x00020000

so it can be compiled and downloaded using a bootloader

    If you take the standard sys_link.cmd generated by HALCoGen and then modify the MEMORY section to move the start of the VECTORS and FLASH0 sections up by 0x20000 and decrease the size of FLASH0 by 0x20000.

    MEMORY
    {
        VECTORS (X)  : origin=0x00020000 length=0x00000020
        FLASH0  (RX) : origin=0x00020020 length=0x0015FFE0
        FLASH1  (RX) : origin=0x00180000 length=0x00180000
        STACKS  (RW) : origin=0x08000000 length=0x00001500
        RAM     (RW) : origin=0x08001500 length=0x0003EB00
    }

    The boot loader then would handle reset by branching to location 0x20000. The instruction at that location is a branch instruction to the beginning of your application code.
