Launching the command md shows that the file has actually been transferred. To load and execute the image I am using the command bootm. Please note that I am using the arndale 5250 KVM uboot version which shall loads the kernel in hyp mode, with the same configuration Many thanks and best regards. -- View this message in context: http://u-boot.10912.n7.nabble.com/Standalone-application-issue-tp180515p180660.html Sent from the U-Boot mailing list archive at Nabble.com. ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

the command bootm 0x43e0 returns the following :

and the program hangs on at this stage giving no sign of life.
Please help what I am missing.
