2440中nandflash學(xué)習(xí)小結(jié)
根據(jù)我的開發(fā)板直接測(cè)量信息得The configuration pin – NCON, GPG[15:13]對(duì)應(yīng)位為1,011
1: Advance NAND flash(1KWords/2KBytes page size, 4/5 address cycle)
0: 8-bit bus width
1: 5 address cycle(NCON = 1)
1: Page=2KBytes(NCON = 1)
1: Advance NAND flash(1KWords/2KBytes page size, 4/5 address cycle)
0: 8-bit bus width
1: 5 address cycle(NCON = 1)
1: Page=2KBytes(NCON = 1)
打開K9F2G08U0的規(guī)格書進(jìn)行信息的驗(yàn)證。如下圖。驗(yàn)證結(jié)果說明硬件圖3不正確,實(shí)際電路板NR5是不焊的。
注意:1 Device=2112Mbits。單位為bits即 =264Mbyte 哦!
