# Embedded_Linux

This repo will contain some projects that I've faced during learning Embedded Linux.

- If you have a problem with HDMI in RPI-4 : 

	- config.txt content :

	

		max_framebuffers=2

		force_hotplug=1

		hdmi_force_hotplug:0=1

		#hdmi_safe=1

		config_hdmi_boost=4

		hdmi_group:0=1

		hdmi_mode:0=4

		#arm_64bit=0

		boot_delay=1

	

	- cmdline.txt content : 

		video=HDMI-A-1:1024x768@60D

- I had a problem for not booting and stucking at image of raspberry 

	- Add to config.tst

		kernel=yourImage.img

- Problem :  end kernel panic not syncing attempted to kill init raspberry

	It happened because the kernel tries to run systemd code.

	running file /sbin/init show us a 64 bit executable.

	so kernel tries to run 64-bit on 32-bit image.

	- The solution is to delete /sbin/init

	

- problem : Entering in initramfs : 

	solution : fix the rootfs in your cmdline.txt

- problem : not detecting wlan0 ?

	solution : add arm_64bit=0

	solution 2 : add the right modules for the right (uname -r)
