Other Parts Discussed in Thread: TMS320F2812
I does project TMS320F2812.
environment-----------------------------------------------------------------------
used : Flash Memory , extern memory 1.2Mbyte(chip : SSD1936)
Zone6 and Zone2 : each 512Kbyte allocation
extern memory : ZONE6 connected at XZCS6AND7n, Zone2 none
-------------------------------------------------------------------------------------------
Q1. we hope to ZONE2 and ZONE6? How to use concurrency control ? How to shall we use double Buffer?.
Q2. We must be confirm Flash memory and RAM Used space / Total Space?

fellow above korean question,,,, same english
두가지 질문 있습니다.
TMS320F2812으로 프로젝트 하고 있습니다.
Flash Memory 정보 아래와 같이 사용하고 있고,
외부메모리로 1.2M 짜리 Frame Buffer 칩(SSD1936) 를
ZONE6붙여서 XZCS6AND7n 사용 연결하고 있으며, ZONE2에는 연결 되어 있지 않습니다.
1. ZONE2와 ZONE6를 동시에 Frame Buffer 칩(SSD1936) 연결하여 칩 셀렉트 선택적으로 사용이 가능한지? 일종에 Double Buffer 형태로 사용 가능할지요?
2. 정식 Debug제품으로 플레쉬메모리와 RAM사용에 따른 총용량과 사용하고 있는 용량 확인이 가능한지 ? 가능하면 어떻게 해야 되는지 알고 싶습니다.
