ARM, RISC-V контроллеры

Сорри за кросспост. Пытаюсь собрать демо-проект для LPC4357 под ChibiOs. Среда - ChibiStudio (Eclipse/GCC + плагин для ChibiOs). В результате сборки получаю сообщение "make: *** No rule to make target `build/LPC4357.elf', needed by `all'. Stop." Исходные файлы компилируются без ошибок. Никак не удается победить. Кто силен в данной теме, гляньте, плиз, makefile. Источник проекта - SourceForge, автор TheShed.
