You should undefine CONFIG_SKIP_LOWLEVEL_INIT - in "include/configs/adp-ag101.h". - -Build and boot steps -==================== - -build: -1. Prepare the toolchains and make sure the $PATH to toolchains is correct. -2. Use `make adp-ag101` in u-boot root to build the image. - -burn u-boot to flash: -1. Make sure the MA17 (J16) is Lo. -2. Make sure the dip switch SW5 is set to "0101". -3. Power On. Press button "S1", then press button "SW1", then you will found the - debug LED show 67 means the system successfully booted into e-bios. - Now you can control the e-bios boot loader from your console. -4.
