Hi,
I am using a nrf52840 dongle with a jlink mini on the latest nRF Connect. I have modified the board dts file to reflect that I am using an external debugger: include "fstab_debugger.dts" and I have also set BOARD_HAS_NRF5_BOOTLOADER to "n". Running examples works fine. I have now tried to add CONFIG_BOOTLOADER_MCUBOOT=y and I get a flash overflow. Other posts I have searched (see here (https://devzone.nordicsemi.com/f/nordic-q-a/77252/nrf52840dongle_nrf52840-config_bootloader_mcuboot-y-partition-to-small) seem to indicate that the problem for the overflow is the NRF USB bootloader - which I don't use.
As the application code is small, I guessed the problem is with mcuboot not fitting somewhere, but I could not find out what is the problem. When comparing the flash layout with the 52840DK, the space reserved for mcuboot on the dongle is even larger than on the DK:
Dongle:
boot_partition: partition@0 {
label = "mcuboot";
reg = <0x000000000 0x00012000>;
};
slot0_partition: partition@12000 {
label = "image-0";
reg = <0x00012000 0x000069000>;
};
slot1_partition: partition@7b000 {
label = "image-1";
reg = <0x0007b000 0x000069000>;
};
scratch_partition: partition@e4000 {
label = "image-scratch";
reg = <0x000e4000 0x00018000>;
};
storage_partition: partition@fc000 {
label = "storage";
reg = <0x000fc000 0x00004000>;
};
DK:
boot_partition: partition@0 {
label = "mcuboot";
reg = <0x000000000 0x0000C000>;
};
slot0_partition: partition@c000 {
label = "image-0";
reg = <0x0000C000 0x00067000>;
};
slot1_partition: partition@73000 {
label = "image-1";
reg = <0x00073000 0x00067000>;
};
scratch_partition: partition@da000 {
label = "image-scratch";
reg = <0x000da000 0x0001e000>;
};
storage_partition: partition@f8000 {
label = "storage";
reg = <0x000f8000 0x00008000>;
};
I would like to understand what goes wrong here. mcuboot and a small application should fit onto the 1MB flash I'd guess. I know the dongle is not recommended for development (need a debugger, only 1 button etc), but it should be no problem to use with mcuboot? The same code compiles correctly when configured for the DK. I have tried to use the dts settings from the DK on the dongle, but the flash overflow error remains, so the problem does not seem to come from the partition layout. I also attach the build output:
