Ok i tried this, and now the reboot loops seems to be gone. The blue "done" led now only switches "on" one time and stays on. Unfortunatly i still don't see anything on the console in this case. I can see that the registers lr 0x1d70 0x1d70 pc 0xcf6c 0xcf6c But according to the u-boot map there is nothing and i am not sure how to get information about the relocation without u-boot command line.

Removeing OF_CONTROL gives a compile error: xilinx/zynq/u-boot-xlnx/arch/arm/lib/board.c:633: undefined reference to `checkboard' lib/built-in.o: In function `rsa_verify_with_keynode': xilinx/zynq/u-boot-xlnx/lib/rsa/rsa-verify.c:284: undefined reference to `fdtdec_get_int' > If you use ML, as Michal said - u-boot operates through FDT support. > But I guess even if you use u-boot.elf with FDT enabled, you must get > the below error > ** CONFIG_OF_CONTROL defined but no FDT - please see doc/README.fdt-control" Mh, i now appended the fdt in the bif file.

Does this mean that the serial drivers are statically defined and do not take the device tree file into account? > Please check and may be you can try u-boot-dtb.elf. Mh, don't know how to create this kind of file? Best regards Tim _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
