![]() When applying DTBO on top of DTB (with "fdt apply" command) on AM57x EVM board, there is not enough memory reserved in RAM for DTB blob. Hence, DTBO can't be merged in DTB. It leads to inability to boot Android with next error message: failed on fdt_overlay_apply(): FDT_ERR_NOSPACE To overcome that issue let's provide 512 KiB of space to keep DTB and all merged DTBO blobs. To do so, "length" parameter should be specified for "fdt addr" command: => fdt addr $fdtaddr 0x80000 512 KiB is the maximum size we can use for this, because next address after $fdtaddr is 512 KiB ahead of it: fdtaddr=0x88000000 rdaddr=0x88080000 Also add size variables to 'adtimg' command invocations, to avoid cluttering the console with DTBO blob sizes.
