LP-CC1352P7: SBL firmware update not working

Job Meulenbeld
Prodigy 10 points
Part Number: LP-CC1352P7
Other Parts Discussed in Thread: UNIFLASH

Tool/software:

Hello!

I am currently trying to figure out how the SBL works (using this PDF). I use UniFlash to upload over serial to the SBL. But whenever I try, it somewhat indicates a success, but when exiting the SBL it does not run my program. I do the following steps:

  • I select the binary file in UniFlash
  • I select the right comport
  • I reset the device with the GPIO enabled to enter the SBL
  • I load the program
  • I power cycle the device

The console output seems to indicate a success, but I do get an error. After uploading I power cycle the device (without the backdoor GPIO enabled) but it does not run the program. I checked the memory after flashing and it seems to have uploaded the firmware, but I don't know if everything is correct. Any ideas?

With kind regards,
Job Meulenbeld

    Hi Job,

    When the devices boots, it has three choices:

    a) If a debugger is attached, it will halt in boot (this is what happens if you use CCS to start a debug session)

    b) If the bootloader backdoor is activated or there is no valid image, go to the serial bootloader and wait to receive an image

    c) Start the application image.

    If you load an image where bootloader is enabled and bootloader backdoor is defined, then restart the device while activating bootloader backdoor (typically by holding a button), the device will go into serial bootloader where it's waiting for an image, i.e. not running the application. Is this the scenario you are describing?

    Cheers,
