I just checked the current master as well as v2016.11-rc1, no issue with anyone. Heres the log: U-Boot 2016.11-rc1 (Oct 07 2016 - 15:52:28 -0700) DRAM: 8 MiB WARNING: Caches not enabled Flash: 1 MiB Using default environment In: serial_stm32x7 Out: serial_stm32x7 Err: serial_stm32x7 Net: Net Initialization Skipped No ethernet found.
