Configurations ^^^^^^^^^^^^^^

Each PNEV5180B configuration is maintained in a sub-directory and can be selected as follow:

cd tools
./configure.sh pnev5180b:<subdir>
cd -

Where <subdir> is one of the following:

nsh: Configures the NuttShell (nsh) located at apps/system/nsh. The Configuration enables the serial NSH interface.

NOTES:

1. This configuration uses the mconf-based configuration tool.  To
   change this configurations using that tool, you should:

   a. Build and install the kconfig-mconf tool.  See nuttx/README.txt
      see additional README.txt files in the NuttX tools repository.

   b. Execute 'make menuconfig' in nuttx/ in order to start the
      reconfiguration process.

usbnsh: Configures the NuttShell (nsh) located at apps/system/nsh. The Configuration enables the CDC/ACM based NSH interface on /dev/ttyACM0.

nsh-cdcecm: Configures the NuttShell (nsh) to provide a terminal on UART0. The Configuration also provides network interface eth0 via CDC/ECM.

usbnsh-cdcecm: This configuration includes a USB Composite Device with both CDC/ACM and CDC/ECM. NuttShell provides a terminal via CDC/ACM. A network interface (eth0) is also provided via CDC/ECM.

knsh: This is identical to the nsh configuratio above except that NuttX is built as a kernel-mode, monolithic module and the user applications are built separately.
