Hi,
thanks for your answer.
BOARD_ARM_GENERIC_DT [=y] and BOARD_ARM_GENERIC_DT_AARCH64 [=y] were already set,
so i just copied the
arch/arm/dts/rk3568-bpi-r2-pro.dtb
and the
images/barebox-dt-2nd.img
to my sdcard and could it boot this way (using booti instead of bootm) :)
=> fatload mmc 1:2 ${kernel_addr_r} barebox-dt-2nd.img
reading barebox-dt-2nd.img
403792 bytes read in 38 ms (10.1 MiB/s)
=> fatload mmc 1:2 ${fdt_addr_r} rk3568-bpi-r2-pro.dtb
reading rk3568-bpi-r2-pro.dtb
35602 bytes read in 8 ms (4.2 MiB/s)
=> booti ${kernel_addr_r} - ${fdt_addr_r}
so problem solved ;)
regards Frank
