I download an APP bin file through UART Bootloader for Hercules TMS570LS31x Microcontroller to the TMS570LS3137 HDK.How to change the CMD file of the bootloader and the app?In the bl_config.h we can see "#define APP_START_ADDRESS 0x00020000"
the bootloader CMD:
MEMORY
{
VECTORS (X) : origin=0x00000000 length=0x00000020
FLASH_API (RX) : origin=0x00000020 length=0x000014E0
FLASH0 (RX) : origin=0x00001500 length=0x002FEB00 //LS31x and RM48 Flash size is 0x300000
STACK (RW) : origin=0x08000000 length=0x00002000
SRAM (RW) : origin=0x08002000 length=0x0002D000
}
SECTIONS
{
.intvecs : {} > VECTORS
flashAPI :
{
Fapi_UserDefinedFunctions.obj (.text)
bl_flash.obj (.text)
--library=..\lib\F021_API_CortexR4_BE.lib (.text)
} load = FLASH_API, run = SRAM, LOAD_START(api_load), RUN_START(api_run), SIZE(api_size)
.text > FLASH0
.const > FLASH0
.cinit > FLASH0
.pinit > FLASH0
.data > SRAM
.bss > SRAM
}
the app CMD:
/*----------------------------------------------------------------------------*/
/* Linker Settings */
--retain="*(.intvecs)"
/* USER CODE BEGIN (1) */
/* USER CODE END */
/*----------------------------------------------------------------------------*/
/* Memory Map */
MEMORY

I changed the two CMD files as follows:
But the app doesn't run and the LED D1 on the HDK brights out.It seems that an error occurs.
the changed bootloader CMD:
--retain="*(.intvecs)"
