Small linux system image (ca. 30MB compressed) for MangoPi MQ Dual (F133/D1s cpu) board. System was built using the customized buildroot configuration.
Login:
u:root
pwd: mangopi
Default Wifi configuration:
# cat /etc/wpa_supplicant.conf
ap_scan=1
network={
ssid="YOURSSID"
scan_ssid=1
key_mgmt=WPA-PSK
psk="YOURPASSWD"
}
To generate encrypted password:
# wpa_passphrase yourssid yourpasswd
Replace your plaintext password in /etc/wpa_supplicant.conf
When Wifi is configured restart networking and check your ip after a moment:
# /etc/init.d/S40network restart
# ip a
Now you can login via ssh also.
What the system includes:
- linux kernel 6.6.0-rc7 riscv64
- swap memory support - you may run low on RAM!
- ssh server (dropbear)
- python 3.11.6 with modules
libevdevspidevsmbus_cffiserialrequestscan - preinstalled CA certificates
nanotext editor- vfat/exfat/ext2 support and tools
htopandiotopfor monitoring- simple demo scripts under
