SDK 17.1.0 example dfu/secure_bootloader does not fit in FLASH

[Gauthier]

I just downloaded the SDK 17.1.0_ddde560.

Going to `examples/dfu/secure_bootloader/pca10056_s140_ble/armgcc`, then running:

CFLAGS=-DNRF_DFU_DEBUG_VERSION make

Gives me this:

Building on Ubuntu 20.04 with arm-none-eabi 9.2.1.

Version of ld:

$ /usr/lib/arm-none-eabi/bin/ld --version
GNU ld (2.34-4ubuntu1+13ubuntu1) 2.34

I was expecting this example (with debug enable to skip generating a real key) would work out of the box. What could possibly be wrong?

[Gauthier]

It's working, building with arm-none-eabi version 10.3.1, downloaded from ARM.

(requires the envvars as usual:

export GNU_INSTALL_ROOT=/opt/gcc-arm-none-eabi-10.3-2021.07/bin/
export GNU_VERSION=10.3.1
export GNU_PREFIX=${GNU_PREFIX:-arm-none-eabi}

Hi, 

Good to know it works, but I think you should use the debug version of the bootloader as pca10056_s140_ble_debug in your case. 

Regards,

[Gauthier]

Interesting! Why do you think that?

[Amanda Hsieh]

The bootloader with _debug has the log functions to help debug and also reserve the flash area for that. You can see the bootloader addresses of these two versions (with/without _debug) are different.
