I'm using a nRF54L15-DK, going through lesson 9 of the intermediate tutorials, using the ncs-inter files at commit 2475c72: Update mcuboot.conf · NordicDeveloperAcademy/ncs-inter@2475c72 · GitHub, with v2.9.0 of the SDK in Windows 11.
I'm building for target nrf54l15dk/nrf54l15/cpuapp.
I have noticed that for Exercise 2, I am unable to put the board into DFU mode by holding Button 1 while resetting, in order to reprogram via AuTerm. I checked mcuboot.conf, and added the following lines (as I saw in Exercise 1) to enable DFU mode this way:
CONFIG_MCUBOOT_SERIAL=y
CONFIG_BOOT_SERIAL_UART=y
CONFIG_UART_CONSOLE=n
I added those lines, and all worked as described in the tutorial, except that the MCUBoot log output was not present in the VCOM, since I had to disable CONFIG_UART_CONSOLE in mcuboot.conf.
I noticed a similar situation in Exercise 3, and this time I'm unable to get past it; once again, holding Button 1 while resetting would not place the board into DFU mode. This time, though, adding those lines to mcuboot.conf causes a pristine build to fail:

I've attached my config files from the tutorial in case they help.
