Hey, the most probable cause is that this board, because it’s not a Sabre Lite, uses a different board id.
I just had a look, and it actually is the issue. Our SabreLite is defined as: #define BOARD_ID_IMX6_SABRELITE 3769 SabreSD defined in u-boot: #define CONFIG_MACH_TYPE 3980 I can have a look later today and create a kernel for you. It should be rather easy to implement this. Also, the reason why you don’t get serial console output is that the kernel looks at that board id and uses it to determine what console to print to. \Patrick > Am 19.09.2014 um 13:32 schrieb Hrishikesh Muruk <hris...@gmail.com>: > > Hi > > Thanks Patrick.
