NAND flash issue

您好,

我最近更換NAND flash,但碰到以下的問題,請問該怎麼解決?謝謝!!

U-Boot 2010.06 (Aug 30 2017 – 15:04:29) DM385_IPNC_3.50.00

Chris Meng:

Byron,

你新换的nand和之前使用的nand最大的区别是什么?

报错在ubifs文件系统,请问你的文件系统是如果烧写到nand,是在uboot里烧写的么?

Byron Tien:

回复 Chris Meng:

您好,

1>之前的flash是Spansion

Page size : (2048+64) bytes

Block size : (128K+4K) bytes

Total : (2048+64) bytes * 64 pages * 1024 blocks

現在是 Toshiba flash

Page size : (2048+128) bytes

Block size : (128K+8K) bytes

Total : (2048+128) bytes * 64 pages * 1024 blocks

2>我是從 SD卡開機將image燒寫進NAND flash.

ubifs機制有問題,是否在製作mkfs.ubifs與ubinize時參數有誤呢?

Best Regards,

Byron

Chris Meng:

回复 Byron Tien:

Byron.

比较看最大的区别是每个page的spare size,一个是64 bytes,一个是128 bytes。我们的uboot应该用都是BCH8。

还是不理解你是如何从SD卡烧写nand的。是从SD卡启动,然后在uboot里面读取uboot/uImage/ubifs文件系统,然后烧写到nand?

Byron Tien:

回复 Chris Meng:

您好,

1>BCH8是指什麼??以現在toshiba該怎麼改寫?

2>是的SD卡開機後,uboot裡讀取文件系統,將其燒寫入NAND.

Best Regards,

Byron
