nrf52810 dfu can't work

[Brian Qin]

Hi,

I have met problem when apply dfu of nrf52810.

I used dfu sample of 52810 from devzone link: https://devzone.nordicsemi.com/f/nordic-q-a/28471/about-ota-for-nrf52810-on-sdk-v14-1/112571#112571, but I changed sdk to 14.2

the app is modified from project of ble_app_buttonless_dfu,

the memory address set as below:

IROM1 start 0x18000, size 0x1000, IRAM1 start 0x200024F8,size 0x3B08.

the app package generate by command: nrfutil pkg generate --hw-version 52 --application-version 4 --application nrf52810_xxaa.hex --sd-req  0xA6  --key-file private.key dfu52810.zip

the dfu process never started, what is the issue? or can you share a project of dfu app which is well validated?

thanks!

Brian Qin.

I tried it on 52832 with option of DEVELOP_IN_NRF52832, dfu is ok, memory addresses are same, also it is ok with app size over half of 64k, I think it turn to single band automatically,

but on 52810, Dfutarg can be found and connected, but it never start dfu process,
