hi,
Can we use sqspi(nrf54l15) with MCUboot, since it has ota DFU support?
i have tried but it is not working(device showing no response).

Please take a look at the Devacademy course at https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-9-bootloaders-and-dfu-fota/ or create a new support case for your issue.

Hi nzgupta , I would be very grateful if you could share the basic configuration for mcuboot enable (config, dts files ). I've enabled it, built and flashed it successfully, but I can't start the program. It seems to be stuck in MCU boot mode; I don't see any logs being dumped in JTAG.

Thanks a lot!

Happy to know it works now. 🙂

I'm using the internal LF crystal. I had initially configured those options for the prj.conf file, but not the mcuboot.conf file. Once I added it to the mcuboot.conf file, the application ran as expected. Thanks for the help.

Hi,

Do you use internal or external LF crystal on the custom board?
If you use the internal RC oscillator as 32KHz clock source, the following configs to your prj.conf and sysbuild/mcuboot.conf.

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y

CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n
