Hi mr_sev,

I am seeing the same problem as in your "update app faile" case when testing here. Will get back to you when we find the solution.

@Mr Sev: Which hardware board are you testing with ? Which chip is on the board ? Have you made sure you setup the device page correctly with the memory layout you have with your board ?

What kind of error do you have when you flash the bootloader with nrfjprog? Please take a screenshot.

I also can reproduce the issue here that occasionally the device crash when DFU got to 1% , I will try to find the reason.

Please remove your answer and long comment, and put them into the question (edit the question and put information there) . It's very hard to read the thread now.

hi Hung Bui, bootloader for mesh, not nRF5 SDK, i can't flash bootloader using nrfjprog, nRFgo Studio can.

Hi Mr_sev,

I assume you are talking about the bootloader for mesh included in the mesh github repo ? Not the serial bootloader included in the nRF5 SDK ?

As far as I know after you flash your application (rbc_gateway_example_serial_blinky_PCA1) , the application should run, not the bootloader. The bootloader only takes place when the DFU images is received and the device switch to bootloader to swap the application.

Could you follow the guide in dfu_quick_start.adoc and let me know the result ?
