昨天 恆濕恆溫機 裡面所謂的 使用 旺宏 NAND Flash 的 M300

Morris 說搞錯了

其實那一台使用的是 SD 卡

0925

幫忙準備昨天 build 好的 image 給 morris 作測試

這兩片都是使用 NAND Flash

一片是 旺宏

一片是 華邦

為了實驗方便

先把 bootdelay 改成 3

0930

發現昨天所謂的對 17 個 暫存器寫值的動作

mw 020e0404 000010b0 1
mw 020e0408 000010b0 1
mw 020e040c 000010b0 1
mw 020e0410 000010b0 1
mw 020e0414 000010b0 1
mw 020e0418 000010b0 1
mw 020e041c 000010b0 1
mw 020e0420 000010b0 1

mw 020e0424 000010b0 1
mw 020e0428 000010b0 1
mw 020e042c 000010b0 1
mw 020e0430 000010b0 1
mw 020e0434 000010b0 1
mw 020e0438 000010b0 1
mw 020e043c 000010b0 1
mw 020e0440 000010b0 1
mw 020e0444 000010b0 1

因為值都相同

可以用 mw 020e0404 000010b0 11 取代

讀值也可以使用 md 020e0404 11

這邊的 11 是 16 進位 - 也就是 10 進位的 17

這邊的 setup_gpmi_nand() 其實就已經把定義在 nand_pads[] 裡的 17 個跟 NAND 相關的暫存器都設定好了

實在不太明白為何同一組值我利用 U-Boot 的 mw 再去寫一次就讓 NAND Flash 動作變正常了

這個線索就先放著吧

那我連 boot_env 這塊 MTD 都讀不到的話

根本連使用 mw 去寫暫存器的機會都沒有

看來還是要去修改 U-Boot 才行

拿 華邦 來分析問題

雖然 uboot 有成功的把 linux kernel 載入到 DDR 作執行了

但更大的 rootfs 的讀取還是會出錯

應該可以利用華邦這一台來調整一下 暫存器 適合的值
