Hi,

[quote user="Wayne_Chang"]Are the partitions' names what I wrote correct?[/quote]

This looks good. I take it DFU works via BLE now?

[quote user="Wayne_Chang"]can I generate new app_update.bin, and use jlink or something to programming bin file to mcuboot_secondary, and then swap to mcuboot_primary ?[/quote]

In principl yes, but it is not enough to just write the firmware image. There is also other metadata that is written together with the image normally via the SMP protocol. So you would have to write this in the image trailer as well via the debugger before you reset if you want to test like this.

Hi Einar Thorsrud,

thanks for your answer

the flash map below is reading after BLE FOTA

Are the partitions' names what I wrote correct?

if so, can I generate new app_update.bin, and use jlink or something to programming bin file to mcuboot_secondary, and then swap to mcuboot_primary ?

for example:

mcuboot_secondary:
  address: 0x85000
  end_address: 0xfe000

I programming new bin file to 0x85000 then I want mcuboot update this to app slot

Hi,

Wiht nRF Connect SDK, bluetooth updates are always done with dual application slots (never single slot). That is because the transprot must happen in the application.

Hi swallowirritate,

thanks for your answer

I already use
CONFIG_BOOTLOADER_MCUBOOT=y
CONFIG_NCS_SAMPLE_MCUMGR_BT_OTA_DFU=y

after I add CONFIG_UPDATEABLE_IMAGE_NUMBER=2

I encounter a problem when i build the code

/home/ncs/v2.4.0/nrf/include/flash_map_pm.h:41:22: error: 'PM_mcuboot_primary_1_ID' undeclared (first use in this function); did you mean 'PM_mcuboot_primary_ID'?
   41 | #define PM_ID(label) PM_##label##_ID
/home/ncs/v2.4.0/nrf/include/flash_map_pm.h:41:22: error: 'PM_mcuboot_secondary_1_ID' undeclared (first use in this function); did you mean 'PM_mcuboot_secondary_ID'?
   41 | #define PM_ID(label) PM_##label##_ID

do I need to add something else in my `prj.conf`?

Yes, you can use double-slot firmware updates over BLE (FOTA) in NCS (nRF Connect SDK) 2.4.0
To enable double-slot swapping, you need to add the following to your project's `prj.conf`:
CONFIG_BOOTLOADER_MCUBOOT=y
CONFIG_UPDATEABLE_IMAGE_NUMBER=2
