Trying running nrf_sdk 1.17.x scured bootloader UART example

[alonmat]

Currently I learn the current DFU example from nrf_sdk but I failed in the last step:

1. I compiled the bootloader example secure_bootloader\pca10056_uart
   1. in the process i created  private keys
2. I burn the bootloader into the evaluation board pca10056 using Segger Studio tool (SES)
3. I run the board and I got 2 leds (leds 1,3) on as expected. now the bootloader run on the evaluation board and wait for the application
4. I compiled an example simple blinky tool without ble: peripheral\blinky\pca10056
   1. I created a zip file using this tool
      1. nrfutil pkg generate --hw-version 52 --sd-req 0x00 --application-version 1 --application blinky_pca10056.hex --key-file private.pem blinky_dfu.zip
   2. I tried to upload create  example zip file using:
      1. nrfutil dfu serial -pkg blinky_dfu.zip -p COM27 -b 115200 -fc 1
   3. The nrfutil burn it via the bootloader and I a message in the terminal: Device programmed
   4. The evaluation board didn't blink any led. It means the example failed to run after burning

Why the blinky application doesn;t work after burning ?

maybe the some macros has wrong values ?

FLASH_PH_START=0x0

FLASH_PH_SIZE=0x100000

RAM_PH_START=0x20000000

RAM_PH_SIZE=0x40000

FLASH_START=0x1000

FLASH_SIZE=0xFF000

RAM_START=0x20000008

RAM_SIZE=0x3FFF8

I retested these same steps and it works now.

The blinky app was running after burning via the bootloader
