Хочу собрать современное ванильный u-boot (v2019.04). Делаю следующие команды:
export ARCH=arm
export PATH=/opt/gcc-linaro-7.4.1-2019.02-x86_64_arm-linux-gnueabi/bin/:$PATH
export CROSS_COMPILE=arm-linux-gnueabi-
make mrproper
make mrproper O=/tmp
make mx28evk_config O=/tmp
make -j $(nproc) O=/tmp u-boot.sb
/tmp/tools/mxsboot sd /tmp/u-boot.sb /mnt/u-boot.sbФлешку подготовил согласно
инструкции раздел 3.
Но после установки не может загрузиться. Запускается SPL, но не переходит на загрузку основной части кода U-Boot.
