UART bootloader DFU update not working

[amarin]

Hi,

I am currently trying to run the secure_bootloader example given the in the sdk 15.2.0. I have successfully been able to update an application onto my NRF52840 DK and am now trying to update the bootloader via UART. However, the error seen in the picture keeps popping up. I think I am missing something when I am creating the zip file with the bootloader update, but I do not know what I am missing. The creation of the zip file can also be seen in the picture. My question is what am I missing that keeps causing this error to happen?

Any help is greatly appreciated!

I am currently running the project found in this path: nRF5_SDK_15.2.0_9412b96\examples\dfu\secure_bootloader\pca10056_uart\ses\Output\Release\Exe

I did not know how to check if the bootloader updated if I am uploading the same bootloader so I do not think about doing something like that. I have since ditched the idea of using that bootloader and have now decided to upload the ble_app_bootloader example rather than the debug bootloader found in this path: nRF5_SDK_15.2.0_9412b96\examples\dfu\secure_bootloader\pca10056_ble\ses\Output\Release\Exe . I decided to use this to make it less confusing, see the obvious difference in bootloaders to check if there was an update and test to see if the new bootloader works after the update. So far though it is still giving me the same error.

Hi,

Sorry for the delay.

 You can use the uart_debug example bootloader image and modify the log to indicate the different version.

 I will take the time to look into it.
