LAUNCHXL-F280049C: Inquiry about the phenomenon that the second kernel does not work when doing LIVE DFU

Hello, 

I see that you are trying to write in an application image to Bank 1, step 9 in the guide outlines how to write an application image into Bank 0 after writing in the kernel to Bank 1. 

Since you also mentioned this:

Live DFU works well when Kernel ex2 is individually executed in Bank0, Bank1.

What sequence of steps are you following when running into the issue you mentioned?

Thanks,

I'll re-list them in the order I did them.

1. After turning on SCI Mode, write flashapi_ex2_sci_kernel(BANK0_LDFU_ROM) to Bank 0

serial_flash_programmer.exe -d f28004x -k f28004x_fw_upgrade_example\flashapi_ex2_sci_kernel.txt -a f28004x_fw_upgrade_example\flashapi_ex2_sci_kernel_BANK0_LDFU_ROM.txt -p COM16 -b 9600

After that 1.DFU run and then 0.EXIT

2. After turning on Flash Mode, write flashapi_ex3_live_firmware_update(BANK1_FLASH) in Bank 1.

serial_flash_programmer_appln.exe -d f28004x -k f28004x_fw_upgrade_example\flashapi_ex2_sci_kernel.txt -a f28004x_ex3_test\flashapi_ex3_live_firmware_updateBANK1FLASH.txt -p COM16 -b 9600
After that, after running 8.Live DFU, 0.EXIT

3. After turning on SCI Mode, write flashapi_ex2_sci_kernel(BANK1_LDFU_ROM) to Bank 1.

serial_flash_programmer.exe -d f28004x -k f28004x_fw_upgrade_example\flashapi_ex2_sci_kernel.txt -a f28004x_fw_upgrade_example\flashapi_ex2_sci_kernel_BANK1_LDFU_ROM.txt -p COM16 -b 9600
After that 1.DFU run and then 0.EXIT

4. After turning on Flash Mode, write flashapi_ex3_live_firmware_update(BANK0_FLASH) in Bank 0.

serial_flash_programmer_appln.exe -d f28004x -k f28004x_fw_upgrade_example\flashapi_ex2_sci_kernel.txt -a f28004x_ex3_test\flashapi_ex3_live_firmware_updateBANK0FLASH.txt -p COM16 -b 9600

After that, after running 8.Live DFU, it stops.

Minseung,

Can you please let me know what version of C2000Ware is being used here i.e. for the Flash kernel?

Thanks,
