When booting we see: DRAM: 256 MiB <strange characters>FSL_SDHC: 0, FSL_SDHC: 1 auto-detected panel vga-rgb The should be: DRAM: 256 MiB PMIC: device id: 0x10, revision id: 0x11, programmed MMC: FSL_SDHC: 0, FSL_SDHC: 1 auto-detected panel vga-rgb This seems to be caused by the call to initr_serial which in our configuration goes into drivers/serial/serial-uclass.c serial_initialize(). Printing an empty line helps. The empty line gets deleted and no strange characters appear.
