armbianEnv.txt - overview-

[denni_isl]

Where can one find a overview of all possible parameters for armbianEnv.txt?

[Igor]

There is no such overview - parameters can be different from kernel to kernel. Too much work for something almost nobody will notice. One parameter that is common for all is extraargs= which is directly translated to https://www.kernel.org/doc/html/v4.14/admin-guide/kernel-parameters.html Peek into boot.cmd script to understand how those parameters are passed on.

 

Then others - like verbosity - is just extracted from there. Then you have overlays and its parameters. That is different from kernel to kernel. Its directly tied to the hardware.

Just a brief question.

Is it possible to pass something similar to this into armbianEnv.txt?

 

bootargs=root=/dev/mmcblk1p1 rw rootwait console=tty0 console=ttyMSM0,115200n8 rootfs=ext4 noinitrd selinux=0
bootcmd=ext4load mmc 1:1 ${kernel_addr_r} /boot/uImage; ext4load mmc 1:1 ${fdt_addr_r} /boot/apq8016-sbc.dtb; bootm ${kernel_addr_r} - ${fdt_addr_r}
uenvcmd=run bootcmd

 

Actually particularly to be more precise -

bootcmd=ext4load mmc 1:1 ${fdt_addr_r} /boot/apq8016-sbc.dtb;

armbianEnv.txt is designed to pass just a few parameters, while the rest - the unchangeable part - remains in the boot script which is on you to code together for your purpose.
