Hi Nordic:

I read nwp_029.pdf anf download  zephyr-v2.2.1,compile  samples/bluetooth/hci_uart  but fail, What's wrong with the operation?

Hi Nordic:

I find it's my mistake,cmd should "cmake -DBOARD=nrf52840dk_nrf52840 -DCONF_FILE=nrf52840dk_nrf52840.conf ..",and not"cmake -DBOARD=nrf52840dk_nrf52840 -DCONF_FILE=nrf52840dk_nrf52840.conf ",but no .hex/.bin file.

Hi,

 

To get the toolchain running properly, including environmental variables, please see the zephyr documentation:

https://docs.zephyrproject.org/latest/getting_started/toolchain_3rd_party_x_compilers.html#rd-party-toolchains

 

From your screenshot, it now selects microsofts compiler. You need to set the env. "ZEPHYR_TOOLCHAIN_VARIANT" to "gnuarmemb" and "GNUARMEMB_TOOLCHAIN_PATH" to the path of the compiler as well. Remember to delete the build folder when changing such variables

 

If you want to use SES NordicEdition, please follow nRF connect for desktop -> "Getting started assistant", as linked here:

Kind regards,

Håkon
