NCS 1.9.1
I have successfully downloaded app_update.bin to flash and rebooted. MCUBOOT copies the new application correctly and it runs fine.
The boot process after the download takes about 60 seconds, so I would like my LED to light during this time so the user knows something is running.
I included
CONFIG_MCUBOOT_INDICATION_LED=y
in the proj.cnf for mcuboot, but I get this message during compilation:
warning: MCUBOOT_INDICATION_LED (defined at D:\NordicSemi\v1.9.1\bootloader\mcuboot\boot\zephyr\Kconfig:505) was assigned the value 'y' but got the value 'n'. Check these unsatisfied dependencies: MCUBOOT_SERIAL (=n). See http://docs.zephyrproject.org/latest/reference/kconfig/CONFIG_MCUBOOT_INDICATION_LED.html and/or look up MCUBOOT_INDICATION_LED in the menuconfig/guiconfig interface. The Application Development Primer, Setting Configuration Values, and Kconfig - Tips and Best Practices sections of the manual might be helpful too.
If I enable the MCUBOOT_SERIAL, then I have to turn off the console, which I want. I'm not trying to do serial recovery, just download and reboot. The link referenced there goes nowhere, and I don't see why the LED should only be available for the serial recovery.
Is there a way to make mcuboot turn on the LED?
