안녕하세요.

고도리입니다.

근래 Magiceyes의 MP2530 Linux kernel의 메인을 대부분 잡았습니다.

현재 sound driver는 DMA부분의 약간의 버그때문에 동작을 하지 않고요.
(코드는 완성이 되었습니다만, mem to io dma쪽을 제가 동작을 잘 못시키네요
mem to mem은 잘됩니다.)

Framebuffer는 u-boot에서는 작성이 되어 있는 것을 확인 했으나,
kernel단 드라이버가 동작을 애매하게 합니다.

대부분 동작을 확인한 상태고, 코드도 웬만큼 되어갑니다.

메인코딩과 테스트를 담당해 준 김정한, 이장호, 최현진 작업실 삼인방에게
박수를 보냅니다....ㅎㅎ

첨부로 mp2530 product brief랑 datasheet(user manual은 아님)을 올립니다.

^^

참, 칩에 대해서는 http://www.mesdigital.com 가시면 보실 수 있을겁니다.
