Hi Roberts, Thank you this is great news. The reason why I didn't go with kernel version over 3.8.x is because the u-boot that I tried didn't include a default load device tree. So now, I'm trying to use the eMMC Flasher from this link : http://elinux.org/BeagleBoardUbuntu#eMMC:_BeagleBone_Black I have a few problems with the MLO and the u-boot since I have no EEPROM. I used the old MLO which agrees that I'm using a BBB by default. But I'm still blocked on the u-boot part. I tried using the uEnv.txt file with the following args but it is not working: board_name=A335BNLT fdtfile=am335x-boneblack.dtb uenvcmd=run loadimage; run loadfdt; run mmcargs; bootz ${loadaddr} - ${fdtaddr} fdtdir=/boot/dtbs/3.8.13-bone59 My main problems are the following: ** Unable to read file /zImage ** ** Unable to read file /boot/dtbs/3.8.13-bone59/am335x-boneblack.dtb ** Bad Linux ARM zImage magic! Do you know how I could solve this ?
