[ghost]

Hello,
I have successfully built ss_twr_resp. I am getting error while building ss_twr_init. I have send the log here , there is controversy in putchar.

Hi Asmita,

This bug is a known problem in the project due to updates to Segger Embedded Studio causing conflicting types, if you pull from my fork of the project, you should have no problems at all.
I have already submitted a pull request to the maintainer with the fix, whether they read it or not.

I got a similar error:

@RogetK I made the changes to the 2 lines as shown in your PR and it worked.
