Well it is not the problem, I know that my kernel args are missing, I'm just missing informations about how i can pass them to the kernel. With u-boot the following command would get passed for the SD card: setenv bootargs console=3DttyO2,115200n8 vram=3D16M root=3D/dev/mmcblk0p2 rw rootfstype=3Dext3 rootwait Another question, is it possible to set these variables without altering the Barebox files (like at run time or between configuring and compiling). > > Note that this last line is not printed by barebox but by the kernel. > There is a separate=A0kernel build option to enable a console on the > omap serial port.
