MCUBoot without Partition Manager

BenKrug

Hi, I want to implement DFU on an nRF52832 with a mx25r1635f external flash, originally I implement the partitions and everything using the devicetree since I find it a lot more comfortable to use. I followed this proccess: https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/ncs-dfu , but the CONFIG_BOOTLOADER_MCUBOOT option enables the partition manager by default, is there a way to use it with the devicetree method for partitions? I saw that most applications on Zephyr do actually use the devicetree instead of the partition manager, so I expect it to be possible, but couldn't find a way to do it.

    Hi, 

    Which NCS are you using? Is it v2.2.0? If so, You can have .conf and .overly for mcuboot as this example. 

    Regards,
    Amanda H.

    Hi, I tried to build the code, but I'm getting a lot of error messages, I tried taking out a couple of config parameters, even after trying many combinations, I still can't make it build. Do you know what config parameters I need to use for the nRF52832 with SPI-NOR flash, not QSPI?

    Check the CONFIG_PM_PARTITION_SIZE_LITTLEFS value.

    I'm getting this error now when I set CONFIG_PM_PARTITION_SIZE_LITTLEFS to any value bigger than 0xf000:

    do you know what could it be?

    even when the value is 0x7000, it still gives this error:

    Hi, 

    Could you provide the memory layout for the partition, partitions.yml under build folder, overlay, and config files? If you are using pm_static.yml, please also share it.

    The memory report I can't generate, when I try to generate it, it gives me an error.

    Hi, 

    Not sure what causes the issue, but the overlay seems you are using qpsi for mx25r16. If you disable qpsi as following 

    Fullscreen

    2
    3
    &qspi {
    status = "disabled";
    };
    XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

    L114 &mx25r16 will not work because the parent's node &qspi is disabled. To use SPI_NOR driver with your external mx25r16, it should have the thing like this example . Here is my overlay for your reference:

    Then, it would show the FS at the external flash as

    Hi, I don't have it in the QSPI bus, as I'm using a nrf52832 it does not even include a QSPI bus, I have the flash SPI definitions on the dts file for the custom board:

    I forgot to add this piece of code before, sorry.

    Does the issue only happen when the CONFIG_PM_PARTITION_SIZE_LITTLEFS is 0x6000? If not, is it possible to provide the log and the updated overly?

    it happens only when CONFIG_PM_PARTITION_SIZE_LITTLEFS is 0xf000 or more

    Please upload the latest overlay file. Thanks.
