Hi,
1) I want to run the client-mesh from DK sources into Dongle.
So, I did:
- modified the client-dk project: nrf5_SDK_for_Mesh_v4.0.0_src\examples\light_switch_dongle\client by:
a) changing the settings of preprocessor definitions in board PCA10056 -> PCA10059.
b) I also changed the memory addresses: Preprocessor -> Linker -> Section Placement Macros ->
FLASH_PH_START=0x0
FLASH_PH_SIZE=0x100000
RAM_PH_START=0x20000000
RAM_PH_SIZE=0x40000
FLASH_START=0x27000
FLASH_SIZE=0xd9000
RAM_START=0x20002300
RAM_SIZE=0x3dd00
- donwloaded using command-line programmer via the nRF52840 DK board's JTAG, the soft-device.hex and client.hex:
nrfjprog -f nrf52 --eraseall
cd C:\Nordic_Dongle\nrf5_SDK_for_Mesh_v4.0.0_src\bin\softdevice\
nrfjprog -f nrf52 --chiperase --program s140_nrf52_7.0.1_softdevice.hex
cd C:\Nordic_Dongle\nrf5_SDK_for_Mesh_v4.0.0_src\examples\light_switch_dongle\client\build\light_switch_client_nrf52840_xxAA_s140_7.0.1_Release\
nrfjprog -f nrf52 --sectorerase --program light_switch_client_nrf52840_xxAA_s140_7.0.1.hex
nrfjprog -f nrf52 --reset
- after reset nothing happens (like program doesn't start)
2) Besides the option to run the client-mesh directly into dongle (that I still don't know what's wrong in the steps above), I also would like to have a bootloader that allows developer to download a Mesh application via USB or via BLE (air).
I understood from forum discussions that I need a bootloader for Mesh (the original doesn't work with soft-device).
- Hence, I downloaded bootloader (nrf5_SDK_for_Mesh_v4.0.0_src\bin\bootloader\gccarmemb\mesh_bootloader_gccarmemb_nrf52840_xxAA.hex) and then the soft-device and then the client-application.
Again, nothing happens after reset!
- Then, I want to make a bootloader for mesh using source files from this path (nrf5_SDK_for_Mesh_v4.0.0_src\mesh\bootloader). Unfortunately, the sources do not have a Segger project. Hence, I created a new project in segger, added in the headers, the sources from bootloader path, but it seems that i cannot detect&use the CMAkeList. How can I complete the segger project for bootloader such as I can compile it?
3) I would like to know the exact bootstrapping steps in Dongle nRF52840 in both cases with soft-device for BLE or without:
what address chips starts, bootloader runs, bootloader launch application from address xxx ... who runs softdevice from address yyy .... Eventually, what are the functions from bootloader that starts code from a specific address?
Kind regards,
Liv
