SDK12 DFU compilation error

[Henry]

I found we have to build micro-ecc.lib on our own, so I follow the below link to start to build it: Installing micro-ecc

Then, we meet the below to errors:

Makefile:69: Cannot find include folder: ../../config

For workarround we made an empty folder named 'config', and the build passed. Should we put any thing in the config folder?

[Srikar]

config folder should contain sdk_config.h. If you are using example,It contains ../../config and sdk_config.h file

Thank you, is there any problem if we let it just empty?
