Hi Amanda,

Unfortunately the image you have posted has a too small resolution, so I cannot decipher anything in the image.

Greetings

Hi,

[quote user="AHass"][/quote]

It got better again, now failing at the 61th file with the same error:

'cc310_backend_chacha_poly_aead.h: No such file or directory'

The file is under nRF5_SDK\components\libraries\crypto\backend\cc310, and it supposes to be included as in the example:

Could you try this devzone.nordicsemi.com/.../ble_5F00_nfc_5F00_pairing_5F00_reference.zip? Extract the file under nRF5_SDK_17.0.2_d674dde\examples\ble_peripheral\experimental.

Hi,

Thank you for replying. No, I haven't changed anything in the example - of course except the neccessary configurations in sdk_config.h.

I have now gone even more steps back and uninstalled and then reinstalled SES along with the SDK and the nRF Command Line tool. Of course I compiled the micro-ecc library with MinGW again and configured the sdk_config.h so that only micro-ecc is enabled.

It got better again, now failing at the 61th file with the same error:

'cc310_backend_chacha_poly_aead.h: No such file or directory'

It does get better, I really try to stick to the descriptions and tutorials and it still fails.

Do you have any more suggestions on what the issue is?

Hi,

I cannot reproduce the error with the unmodified example. Did you modify the example? If so, what is that?

Yes, it is under nrf52hf_armgcc\armgcc. I now reinstalled the whole SDK, re-compiled the micro-ecc library and opened the SES example project. The compile process now gets further, at least it compiles the nrff_hw_backend_init.c file and seems to find hw_backend_init.asm. But now it does not find "nrf_hw_backend_rng_mbedtls.asm".

Whole error string:

can't open '.../nRF5SDK1702d674dde/nRF5_SDK_17.0.2_d674dde/examples/ble_peripheral/experimental/ble_nfc_pairing_reference/pca10056/s140/ses/Output/Release/Obj/ble_nfc_pairing_reference_pca10056_s140/nrf_hw_backend_rng_mbedtls.asm' for writing: No such file or directory

Maybe I am doing something wrong in SES? Since I am using the "ble_nfc_pairing_reference" example the nRF_micro-ecc file is already in the project (picture below), so I did not include it as described on the corresponding infocenter site. Maybe this is the reason?

Is it under nrf52hf_armgcc\armgcc? If so, try to clean and rebuild the project or redownload the SDK. You should not get an error like that.

Hi,

Tank you for your reply. Yes I did run make. I also did not get any error messages from MinGW and after compiling, I also got the "micro_ecc_lib_nrf52.a" file as mentioned on the corresponding infocenter site. After compiling, the directory looked like in the following image

Hi,

Did you run make to compile the micro-ecc library under nRF5_SDK_17.0.2_d674dde\external\micro-ecc\nrf52hf_armgcc\armgcc as Installing micro-ecc documentation?
