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.
