Kernel bootargs

I’ve got a very simple uboot working here :

It is missing the correct bootargs for the kernel. Does anyone know a good set of bootargs ?
I was thinking of this :

setenv bootargs “root=/dev/mmcblk1 earlyprintk=serial,uart0,115200 rw rootwait”

However it is missing the correct console parameter. Once the kernel boots, the console is no longer output on uart0. Any suggestions for the correct addition to the bootargs line to get the console working ?


You can add this argument. And enable UART0 in device tree file.


Got it thanks.

I ended up using the following bootargs :
setenv bootargs “root=/dev/mmcblk0p2 earlyprintk console=ttyS0,115200n8 rw rootwait”
