Hi. I'm using nRF52832, SDK13, S132V4.0.2. I'm trying to test DFU. I have 2 questions.
Q1. How can I make image for merged files? I can see it works very well when I make zip files as below.
BOOT : nrfutil pkg generate --hw-version 52 --sd-req 0x98 --bootloader-version 0x11 --bootloader boot.hex --key-file priv_0407.pem boot_dfu_package.zip
APPLICATION : nrfutil pkg generate --hw-version 52 --sd-req 0x98 --application-version 0x11 --application application.hex --key-file priv_0407.pem app_dfu_package.zip
SOFT DEVICE : nrfutil pkg generate --hw-version 52 --sd-req 0x98 --softdevice s132_nrf52_4.0.2_softdevice.hex --key-file priv_0407.pem sd_dfu_package.zip
Each DFU operations are very good.
But how can I make zip files merged. for example, boot+application or application + soft device or boot+soft device or boot+application+soft device?
Q2. What if DFU fails? If communication is disconnected during DFU or Something could be happend. Does DFU program save old program? I want to know how it works. Can you give me an advise for it?
I hope your reply.
