Hi,Team,

I'm currently using the nrf54l15-dk. I want to implement our custom app to send firmware data to the nrf54l15-dk, have the nrf54l15-dk receive the firmware data and verify it, and then enter the bootloader program to perform the firmware upgrade. Which code example should I refer to?

My ncs version is v3.0.2.

Thanks.

Hi dede,

Apologies for the long response time. I've spent some time now and then looking into the sample but I'm not able to reproduce it with the hardware I have.

Could you state if this still is a problem for you? 

Kind regards,
Andreas

Hi,

This problem still exists. However, after analysis, we believe that this is related to whether the mobile phone supports PHY_CODED. If PHY_CODED is turned off, then the update will succeed. Now we no longer pay attention to this issue. The main problem is how the hub sets the secondary slot 1 and secondary slot 2 in the off-chip flash. Secondary slot 1 is used for the update of the hub itself, while secondary slot 2 is used to receive the firmware of the terminals connected to the hub.

We have previously discussed this issue.https://devzone.nordicsemi.com/f/nordic-q-a/124777/ota .

Thanks.
