TMS570LS1227: Bootloader can't flash application .const part

Soner Bayram1

Part Number: TMS570LS1227

I am using example TI bootloader, i changed sys_intvecs.asm

    .sect ".intvecs"
    .arm

;-------------------------------------------------------------------------------
; import reference for interrupt routines

    .ref _c_int00
    .ref _dabort
    .ref phantomInterrupt
    .def resetEntry

;-------------------------------------------------------------------------------
; interrupt vectors

resetEntry
        b   _c_int00
undefEntry
        b   undefEntry
        b   #0x10018
prefetchEntry
        b   prefetchEntry
        b   _dabort
        b   phantomInterrupt
        ldr pc,[pc,#-0x1b0]
        ldr pc,[pc,#-0x1b0]

application start address : 0x10020.

my applcation is freeRTOS based application, it's blink LED with a task.

I am creating hex file with Hex Utility. 

Application map has a .const part

Hex file .const part. (there is a ":020000040002F8" above the hex file.)

I am sending data via CAN, when address is come to 0x20F94 with data, I get a error. (FMSTAT = 0x30) INVDAT = 1, CSTAT = 1

When I delete the lines above, i can flash hex but it's not working, because these lines is "sys_vim" array that hold the interrupt functions addresses.

Bootloader HalCOGEN SAFETY INIT section

Application HalCOGEN SAFETY INIT section

ECC Enables on the RAM and FLASH tabs are turned off

    Hello Soner,

    The example code of the CAN bootloader doesn't support HEX format. Only binary file is supported.

    I upgrade the example code.

    I read HEX file and parse on C# desktop application.

    I find the start address, end addresses and size and then I find the sectors in between.

    I calculate the size of application, by summing data length of the lines with data in HEX file.

    This example, It start 0x10020 and finish 0x21194 so it erase sector 4-5-6-7.

    Bootloader starts receiving data. If there is a space between current address and next address, desktop application send next start address and continue send data.

    Everything it's okey until here.

    My problem is when I send the application code ".const" data, bootloader can not flash to MCU.

    I think, I solved the problem.

    I am checking it now on the desktop application and then I'll take it to the bootloader side.
