CCS/TMS570LS1224: TMS570LS1224 :UART bootloader

Hello,

All of the Flash APIs that program, erase, blank check or margin verify must be called from a bank other than the one in which code is being executed. If programming or erasing bank 0 of the device which has only one flash bank, these routines must be executed in RAM.

LS1224 has only one flash bank, your application will be programmed to 0x100100 which is located in the same bank as the bootloader. You have to copy the flash API related code to SRAM and execute them from SRAM.

1. Use the cmd file in TI example as reference.

2. Use the _copyAPI2RAM_ in sys_core.asm to copy flash API to SRAM

Hello QJ,

good day to you 

i edited the bootloader  .cmd and sys_core.asm

i still can't sending my .bin file hyperterminal shows a message of "no response from remote system"     

my  APP_START_ADDRESS       0x00010100

i tried to edit sys_intvecs.asm as below but error led blinking

    .sect ".intvecs"
    .arm

Hello,

Can you locate which instruction caused the issue? Please check the values of ESM status registers.

Hello QJ,

the bootloader works  perfectly 

but i have a question about CRC in the demo

does the bootloader checks for CRC?? if yes how to test that?
