The bootloader examples should only be about 24kB.

Please note that the bootloader project has a .reserved_flash section that is the available flash for the application and the protocol stack.

Thanks, that solved the issues i had with micro-ecc, but...

Why the bootloaders are so big and how come the example in the path below can't fit to the device flash nRF5_SDK_16.0.0_98a08e2\examples\iot\bootloader\pca10040\s132\ses

I would like to create bootloader for nRF52832 with UART DFU, where can i find example with reasonable size?

You need to download the ARM GCC toolchain, please follow the instructions under Install micro-ecc.

About the linking error: there is no permission issue because i can compile other example from this SDK. I tried to put the folder directly on C root in order to make short path but it does not help. It is from the SDK16.0.0.

In addition, i am using SEGGER embedded studio. Where should GCC toolchain be?

I tried the folder "C:\Program Files\SEGGER\SEGGER Embedded Studio for ARM 4.42\gcc\arm-none-eabi\bin" with no success.

[quote user=""]Now i get error message of Linking, " can't open C:/nRF52832/nRF5/examples/iot/bootloader/pca10040/s132/ses/ for reading"[/quote]

Havent seen this error before, could it be a permissions thing?

[quote user=""]In addition, why 'build_all.bat' file under micro-ecc, return error messages on all make files?[/quote]

You have probably not set up the correct path to the GCC toolchain in the Makefile.windows file in components\toolchain\gcc. This is my path.

GNU_INSTALL_ROOT := C:/Program Files (x86)/GNU Tools ARM Embedded/7 2018-q2-update/bin/
GNU_VERSION := 7.3.1
GNU_PREFIX := arm-none-eabi
