Hi @gary.alleven , are you able to flash?
From the above log I see you were able to build with no errors but 1 warning:

11:07:44 Build Finished. 0 errors, 1 warnings. (took 37s.599ms)

The warning is due to a variable that the compiler considers as overflow:

const int8_t __code axradio_phy_rssireference = 0xF6 + 64;

We will fix this warning in the next release of our CMSIS pack.
