It might work with CONFIG_ARM_ATAG_DTB_COMPAT enabled, because the memory configuration from DT is ignored and values from ATAGs are taken instead. I suggest you to change it to 4 banks of 256 MiB. > + chosen { > + bootargs ="root=/dev/ram0 rw ramdisk=8192 initrd=0x41000000,8M > console=ttySAC1,115200 init=/linuxrc"; + }; > + > + serial@13800000 { > + status = "okay"; > + }; > + > + serial@13810000 { > + status = "okay"; > + }; > + > + serial@13820000 { > + status = "okay"; > + }; > + > + serial@13830000 { > + status = "okay"; > + }; > +}; Otherwise looks fine.
