Hello,
I am working with busybox 1.35.0 on a yocto based embedded linux system. The
linux system communicates with another microcontroller over a serial RS485
interface using slip protocol. Part of bringing up the slip network interface
involves running the slattach command. I have added support for the slattach
command to busybox by extending the configuration with CONFIG_SLATTACH=y and
CONFIG_FEATURE_IFCONFIG_SLIP=y. When I run this comand, it results in the
usage being printed out, suggesting that I am using the command incorrectly. My
usage is as follows:
slattach -L -F -p slip -s 115200 /dev/ttyUSB0
The output of running this command is:
Usage: slattach [-ehlLmnqv] [-k keepalive] [-o outfill] [-c cmd] [-s speed] [-p
protocol] tty | -
slattach -V | --version
One thing that confuses me here is the flags being printed out by usage do not
match what is mentioned in the slattach.c source file for the busybox 1.35.0
tarball that bitbake downloads from
https://busybox.net/downloads/busybox-1.35.0.tar.bz. The usage mentioned in the
source code suggests that the flags being passed above are all supported.
Bitbake is not applying any patches or configuration changes that should
influence this.
I must be missing something. Any idea what that might be?
Regards,
~ Maxwell
