Problem solved, as described here: https://devzone.nordicsemi.com/f/nordic-q-a/41922/dfu-support-for-sdk15-2-0/163787#163787

Just change NRF_SDH_BLE_VS_UUID_COUNT 1 to 2. Then, everything works fine.

And the RAM config (I'm using 10040 and SDK15.3) should be,

FLASH_SIZE=0x5a000
RAM_START=0x20002aa8
RAM_SIZE=0xd558

Hi Amanda,

I have tried to set RAM start to 0x20002A98 and size to 0xD568. But when the program trying to run advertising_init(), it reset automatically.

And do you know why RAM_START=0x20002228 RAM_SIZE=0xddd8 works for the ble_app_buttonless_dfu sample code? I used the same softdevice and bootloader, but I didn't get any memory error in the log.

Hi,

Please refer to the log which is instructing you to set RAM start to 0x20002A98 and size to 0xD568.
