Hi,
we are using a custom nRF52840 board with SDK 15.0 and softdevice S140 6.0.0. Flashing the application including DFU and softdevice using SES produces the following memory map (from nrfConnect desktop programmer module):
0 - A18 MBR
1000 - 253c8 Softdevice
2600 - 52864 Application
The application has a size of 182372 bytes. After the application there are some un-identified black sections.
When we do over the air updates to the Device we get a memory map of showing the application being much smaller. The bootloader then jumps to the wrong location in the application.
I would guess that I am not setting the the locations correctly. In SES I am using the following macros:
FLASH_PH_START=0x0
FLASH_PH_SIZE=0x100000
RAM_PH_START=0x20000000
RAM_PH_SIZE=0x40000
FLASH_START=0x26000
FLASH_SIZE=0xda000
RAM_START=0x20002c20
RAM_SIZE=0x3d3e0
To create my package for OTA I use:
nrfutil pkg generate --hw-version 52 --application-version 1 --application payload.hex --sd-req 0xA9 --key-file private.key package.zip
If I flash the device using the nrfToolbox on Android it works and boots into the application.
On the client application we are using IOS DFU pod library latest version. (https://github.com/NordicSemiconductor/IOS-Pods-DFU-Library).
many thanks for your help
Paul
