Hi Torsten,

I see a similar problem when using of-tree. My debugging shows that the of-tree address given to the kernel is outside the memory region that can be accessed by the kernel at start-up (defined by CFG_BOOTMAPSZ), thus the kernel crashes very early without any output. (IMHO this is a bug.) If you are using CONFIG_OF_FLAT_TREE _and_ "disable_of" ist likely that you see the same behaviour, because in that case the "bootm" code still uses the of-tree address (char *of_flat_tree), after copying the standard bd_info data to that address. You could check the pointer that is given to the kernel for the board info data (line 967, parameter 1 of (*kernel) (...)) (or change (*kernel) ((bd_t *)of_flat_tree,... to (*kernel) (kbd,...)

Thank you for the hint. As I don't want to use the of-tree, simply undefining the CONFIG_OF_FLAT_TREE switch does the job for me. The kernel is booting now.

Best regards,

Thomas
