Linker error on example code

[Dudi]

Hi.

I get Linker error when i compile 'iot_secure_dfu_bootloader_secure_dfu_s132_pca10040' example from SDK 16.0.0.

The compilation passed (although i had problem with: 'nrf52hf_armgcc' under 'micro-ecc', which didnt passed makefile), 

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

What is the reason for that?

I tried to mode the folder closer to C root but it did not help.

In addition, why 'build_all.bat' file under micro-ecc, return error messages on all make files?

Regards,

Dudi

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.

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

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?

[bjorn-spockeli]

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.
