I have a Banana Pi bpi-m2u board and I installed debian arm. The problem is when arm is starting, kernel shows some messages, and those ugly messages are being displayed even with plymouth splash screen.
my cmdline.txt is:
dwc_otg.lpm_enable=0 console=serial0,115200 console=tty3 root=/devK/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait quiet splash loglevel=0 logo.nologo vt.global_cursor_default=0 plymouth.ignore-serial-consoles
I even added “dmesg --console-off” to rc.local and “VERBOSE=no” in rcS file, but I did not seen any changes! Is there a way to silent boot?
How can I remove ALL boot messages?
Some logs which seen in console in startup is about mmc drive, I am looking for disabling this driver or any way which resolved this problem. my goal is that these error logs fixed or even hidden: some error logs are as follows:
