Hi Jiaxun, CONFIG_FRAMEBUFFER_CONSOLE is enabled in this config file, but CONFIG_FRAMEBUFFER_CONSOLE depends on CONFIG_FB and CONFIG_FB is not selected in this file. This which causes CONFIG_FRAMEBUFFER_CONSOLE to be unchecked, So it causes these problems.so I selcted CONFIG_FB in this config file.
