When is it possible to do dfu bootloader

[Ola]

Hi Nordic Support,

According to the answer in question: devzone.nordicsemi.com/.../

it is not possible to update the bootloader (which is the case with "bootloader_secure_ble" in "SDK 14" using softdevice "s140_nrf52840_5.0.0-2.alpha_softdevice.hex" for nrf82840 chipset).

Do you have a fix for this? If not, when will it be available? Do you have a workaround available?

/Ola.

Hi Ola,

I checked with the developer and got information that it's fixed in S140 v6.0.6

There is some changes in the header files, you can have a look at the patch we provide in the .zip file for the throughput example to know how to convert your application to work with S140v6

Thank you, /Ola.

Hi again,

Do you have a git diff file for the "/examples/dfu/bootloader_secure_ble" example in SDK 14? If not, in what, and when, will "s140_nrf52840_6.0.0-6.alpha_softdevice.hex" be in an official SDK release?

/Ola.

No I don't have the diff for the bootloader example. But I assume there isn't much change in the header files between S140v5 and S140 v6.

S140 v6.0.0-x would most likely be supported in the next SDK release, but I don't know when. Note that none of the components for nRF52840 are in production stage yet, both SDK and softdevice same with the hardware.
