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

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
.

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
