I want to replace the /etc/network/interfaces file on the resulting image root
file system, so I added a bbappend recipe in my meta-rpilinux directory.
[code]maminej@server:~/Yocto/meta-rpilinux/recipes-core/init-ifupdown$ tree
.
├── init-ifupdown-1.0
│ └── raspberrypi4-64
│ └── interfaces
└── init-ifupdown_1.0.bbappend
2 directories, 2 files[/code]
The bbappend file looks like this:
[code]maminej@server:~/Yocto/meta-rpilinux/recipes-core/init-ifupdown$ cat
init-ifupdown_1.0.bbappend
FILESEXTRAPATHS_prepend := "${THISDIR}/init-ifupdown_1.0/${MACHINE}:"[/code]
And the interfaces file in that directory looks like this:
[code]maminej@server:~/Yocto/meta-rpilinux/recipes-core/init-ifupdown/init-ifupdown-1.0/raspberrypi4-64$
cat interfaces
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# The loopback interface
auto lo
iface lo inet loopback
# Wireless interfaces
iface wlan0 inet dhcp
wireless_mode managed
wireless_essid any
wpa-driver wext
wpa-conf /etc/wpa_supplicant.conf
iface atml0 inet dhcp
# Wired or wireless interfaces
auto eth0
iface eth0 inet static
address 169.254.1.100
netmask 255.255.255.0
iface eth1 inet dhcp[/code]
After I build my image and look in the work build directory for the
init-ifupdown package, I see the correct interfaces file :
[code]maminej@server:~/Yocto/poky/build$ cat
/home/maminej/Yocto/poky/build/tmp/work/aarch64-poky-linux/init-ifupdown/1.0-r7/image/etc/network/interfaces
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# The loopback interface
auto lo
iface lo inet loopback
# Wireless interfaces
iface wlan0 inet dhcp
wireless_mode managed
wireless_essid any
wpa-driver wext
wpa-conf /etc/wpa_supplicant.conf
iface atml0 inet dhcp
# Wired or wireless interfaces
auto eth0
iface eth0 inet static
address 169.254.1.100
netmask 255.255.255.0
iface eth1 inet dhcp[/code]
However, after I burn the image to the SD card with this :
[code]maminej@server:~/Image$ sudo dd bs=4M
if=rpilinux-image-raspberrypi4-64-20231225065644.rootfs.wic of=/dev/sdb
status=progress conv=fsync
26+1 records in
26+1 records out
110503936 bytes (111 MB, 105 MiB) copied, 4.52635 s, 24.4 MB/s[/code]
I see the "wrong/original" file in etc/network:
[code]maminej@server:/media/ROOT/etc/network$ cat interfaces
# /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)
# The loopback interface
auto lo
iface lo inet loopback
# Wireless interfaces
iface wlan0 inet dhcp
wireless_mode managed
wireless_essid any
wpa-driver wext
wpa-conf /etc/wpa_supplicant.conf
iface atml0 inet dhcp
# Wired or wireless interfaces
auto eth0
iface eth0 inet dhcp
iface eth1 inet dhcp[/code]
I am fairly new to Yocto and poky, is it possible that another layer/recipe is
overriding the interfaces file ?
Note that in my local.conf, I am adding openssh recipe with this :
[code]CORE_IMAGE_EXTRA_INSTALL += "openssh"[/code]
