Hi again!

Good to hear that it starts at least. Does it stop at the same amount of KiB every time? If possible, could you enable debug level logging in the smp_svr sample, as well for BT? The latter can be enabled with "CONFIG_BT_DEBUG_LOG=y"? A BLE Sniffer trace could be helpful aswell.

Could you also share your prj.conf for both the app and hci_rpmsg, as well as the "overlay-bt.conf"?

Best regards,
Carl Richard

Thank you for the suggestion, uploading app_update.bin instead of merged.hex indeed does progress the image upload beyond 0%.

Connection timeout on upload reattempt:

The issue that I am facing now regarding smp_svr mcumgr dfu ota is that if the image update via the cli fails before fully uploading the image, any reattempts fails with connection timeout. The workaround is to reboot the board running smp_svr.

Hi again!

Could you try to upload the binary image(app_update.bin) instead? It should be located in the same folder. The mcumgr does not support uploading .hex images as far as I know.

Best regards,
Carl Richard

Attempting to upload the app_signed.hex from /smp_svr/build/zephyr yields the same result with the 0% upload progress.

mcumgr is able to obtain the list of active images on the board.

Hi, On3!

Could you try to upload the "app_update.bin" image instead of "merged.hex" and see if that improves anything?

PS: The Holiday season is upon us, which will leave the Nordic support team understaffed until January 4th, 2021. This means that delayed replies will occur during this time. Sorry about the inconvenience and happy Holidays!
