سلام وقت بخیر
تشکر از سایت سیسوگ و دوستان فعال
کدی رو برای برد sinux f1 نوشتم با lcd و touch هم پورتش کردم و راه اندازی میشه الان میخوام با استفاده از کتابخونه های اموزش bare metal پورت uart رو راه اندازی کنم روی برد چند تا سوال دارم
یک : کتابخونه رو ایمپورت میکنم ولی در قسمت کامپایل کتابخونه ها با دستور make کامپایل نمیشن و خطای undifined میگیرم (احتمالا از فایل make) باید باشه که دوستان اگر میشه راهنمایی کنند.
دو : شدنی هست آیا یا خیر باید به صورت bare metal بنویسم از اول؟
کد main هم به این شکله:
