nRF52832 Programming with Product Example Compiled with GCC

Pratap

While I am trying to Program the nRF52832 with Product Example Compiled with GCC, Smart Remote 3 is not booting up.

    Hello Nordic Support Team,

    I am trying to program the nRFready Smart Remote 3 for nRF52832 by compiling and "nRFready Smart Remote 3 nRF52 v1.2.1alpha" of "smart_remote_3_nrf52"  Projects of "nRF52832\armgcc".

    Here are the steps I followed to to generate the Hex file:

    C:\Nordic Semiconductor\nRFready Smart Remote 3 nRF52 v1.2.1alpha\nRF5x SDK-SR3\examples\ble_peripheral\smart_remote_3_nrf52\Projects\Firmware_nRF52832\armgcc> make
mkdir _build
cd _build && mkdir PCA20023-SR3_nRF52832_Product_Example
Compiling file: drv_acc_bma222e.c
Compiling file: drv_acc_lis3dh.c
.
Compiling file: nrf_crypto_mem.c
Compiling file: nrf_crypto_rng.c
Linking target: _build/PCA20023-SR3_nRF52832_Product_Example.out
text data bss dec hex filename
228368 2340 22780 253488 3de30 _build/PCA20023-SR3_nRF52832_Product_Example.out
Preparing: _build/PCA20023-SR3_nRF52832_Product_Example.hex
Preparing: _build/PCA20023-SR3_nRF52832_Product_Example.bin
DONE PCA20023-SR3_nRF52832_Product_Example

C:\Nordic Semiconductor\nRFready Smart Remote 3 nRF52 v1.2.1alpha\nRF5x SDK-SR3\examples\ble_peripheral\smart_remote_3_nrf52\Projects\Firmware_nRF52832\armgcc> cd ../../../../../../

    Then cd to SDK directory and used "mergehex" to merge the boot, app and softdevice hex files as below:

    C:\Nordic Semiconductor\nRFready Smart Remote 3 nRF52 v1.2.1alpha\nRF5x SDK-SR3>
C:\Nordic Semiconductor\nRFready Smart Remote 3 nRF52 v1.2.1alpha\nRF5x SDK-SR3> mergehex -m .\examples\ble_peripheral\smart_remote_3_nrf52\Projects\Firmware_nRF52832\armgcc\_build\PCA20023-SR3_nRF52832_Product_Example.hex .\components\softdevice\s132\hex\s132_nrf52_5.1.0_softdevice.hex .\examples\ble_peripheral\smart_remote_3_nrf52\Projects\Bootloader_nRF52832\armgcc\_build\PCA20023-SR3_nRF52832_Product_Example_Bootloader.hex -o PCA20023-SR3_nRF52832_Product_Example.hex
C:\Nordic Semiconductor\nRFready Smart Remote 3 nRF52 v1.2.1alpha\nRF5x SDK-SR3> nrfjprog -f nrf52 --program .\PCA20023-SR3_nRF52832_Product_Example.hex --sectorerase
.
Erasing page at address 0x7F000.
WARNING: A UICR write operation has been requested but UICR has not been

Applying system reset.
C:\Nordic Semiconductor\nRFready Smart Remote 3 nRF52 v1.2.1alpha\nRF5x SDK-SR3>

    When I use the Pre-compiled FW it is working as expected:

    C:\Nordic Semiconductor\nRFready Smart Remote 3 nRF52 v1.2.1alpha\nRF5x SDK-SR3> nrfjprog -f nrf52 --program '..\Precompiled Firmware\PCA20023-SR3_nRF52832_Product_Example.hex' --sectorerase
.

C:\Nordic Semiconductor\nRFready Smart Remote 3 nRF52 v1.2.1alpha\nRF5x SDK-SR3>

    I did the comparison of "Smart_Remote_3_nRF52_gcc_nrf52.ld" with "Flash memory layout" it is matching.

    Please let us know am I missing any step here.

    regards, Pratap

    Hi!

    It looks like you're missing the bootloader settings .hex file, which you need to generate before merging all hex files (including that one). Try

    nrfutil settings generate -f nrf52 --application PCA20023-SR3_nRF52832_Product_Example.hex --application-version 0 --bootloader-version 0 --bl-settings-version 1 settings.hex

    Best regards,

    Heidi
