Hi Fabio, thanks for your answer. It took me awhile to setup everything and find the right tools. So I tried CONFIG_ARM_APPENDED_DTB but that does not work. I did not give much credit to that as it is flagged experimental. Then I tried to flash a more recent u-boot but something went wrong. I have still the FlashRom prompt but the ttyACM0 where I can upload the u-boot does not appear anymore on my system. I am totally stuck at this point ... -- Linaro.org ?
