<li style="margin-top: 0; line-height: 1.6em; margin-left: 25px; padding-left: 3px;">I am currently studying FDT support and DMA driver. After finish them, I need to study the mailbox driver, and finally I can start studying the sd card driver. There is a lot of work to support sd card, and I'm afraid I won't be able to finish it before the deadline. These are more complicated than I thought.
If I can't finish them before the deadline, Can I apply for a deadline extension?</li>
