[OTA] Cannot upload different FW through DFU_OTA process

[jli_]

Hi, I have a problem related to DFU OTA through BLE

When performing OTA through Bluetooth, I encountered the following issue:

Firmware built in the same build can be successfully updated via OTA using the nRF Connect App on an iPhone (limited to firmware from the same build). However, if firmware from a different build is used, the following error message appears on UART:

 `<err> mcumgr_img_grp: Failed to open flash area ID 2: -2`

` <err> mcumgr_img_grp: Image upload inspect failed: 5`

How can I update the firmware in different built through BLE with the edge device using OTA ?

I am using nrf5340 + ncs2.4.2

Hello,

Could you share the whole log here? Please use the insert tab to paste the whole log.

Firmware built in the same build can be successfully updated via OTA using the nRF Connect App on an iPhone (limited to firmware from the same build). However, if firmware from a different build is used, the following error message appears on UART:

Please explain what you mean by different builds here. Do you mean different configurations for the same application, or are you trying to build the same application on different hardware? Sorry, I didn't understand this very well.

By seeing the snippet of the log you shared, it looks like the application is failing to open the mcuboot_secondary slot. Are you using an external flash here? I also recommend checking the partition manager file to see that you have properly configured the mcuboot_primary and secondary slots.

 

Kind Regards,

The different build means same configuration with same prj.conf and nrf5340dk_nrf5340_cpuapp.overlay, hardware and application, but only different build time. For example: build_1 and build_2.

I have these three files in my child_image folder for mcuboot.

Hello,

I am attaching a simple sample here for testing. I tested this here with NCS 2.4.2. Could you test if the same issue is happening with this sample? I also recommend trying by giving the swap type confirm only, not the swap type "Test and Confirm" from the NRF Connect app. Please delete the build folder from this file and try to test it.

Kind Regards,

Abhijith
