https://e2e.ti.com/support/processors-group/processors/f/processors-forum/877292/66ak2e05-4k-page-nand-ecc-errors

器件型号：66AK2E05

大家好、我将使用66AK2E05和4K 页 NAND 芯片 Micron MT29F4G08ABBFAH4测试一个定制电路板、其中4K 页、每页256 OOB 字节和256KiB PEB。

为了调整软件、我从 K2E-EVM 源开始执行了以下操作：

U-boot：

  • 在配置标题中启用 CONFIG_SYS_NAND_PAGE_4K、而不是 CONFIG_SYS_NAND_PAGE_2K
  • 将 args_ubi 环境变量中的2048更改为4096

Linux 内核：

  • 注释掉.dts 文件中的所有"ti,cs-*"值，以保留 U-boot 配置的设置，以防新 NAND 的时序太紧

结果是我可以从 U-boot 对 NAND 进行编程、但在 Linux 中、如果我尝试 ubattaching -m 4 (ubifs 分区)、我会得到一个内核错误。 此操作会在从 u-boot 烧录 ubi 映像后执行、并使用 ubiformat 格式形成 MTD 分区： 

[96.019096] ubi0：连接 mtd4
[96.026619] ubi0警告：ubi_io_read：从 PEB 读取64个字节时出错-74 (ECC 错误) 0：0：0、只读64个字节、重试

[96.164028] r4：00000000

此外、尝试读取 NAND 会在每个块中显示 ECC 错误、例如： 

root@myboard：~ nanddump -l 0x4000 /dev/mtd4 >/dev/null
ECC Failed：64
ECC Corrected：0
Number of BAD Blocks：0
Number of BBT Blocks：4
Block Size 262144、page size 4096、OOB Size 256
dump data started at 0x00000000、Ending at 0x00004000...
ECC：8个不可纠正的位翻转(偏移量0x00000000)
ECC：8个不可纠正的位翻转(偏移量0x00001000)
ECC：8个不可纠正的位翻转(偏移量0x00002000)
ECC：8个不可纠正的位翻转(偏移量0x00003000)

此外、U-boot 将 OOB 大小报告为128B、但我认为这并不重要、因为它需要80字节用于 ECC。  我是否需要修改 ECC 布局以考虑更大的 OOB？ 这不能对 ubibattach 在 ubibitformat 后崩溃负责、因此 Linux 代码中必须存在错误(也是)。

我怀疑时序可能也需要放松、但我没有找到一种明确的方法来根据 NAND 规格计算.dts (U-boot 和 Linux)中所需的 ns 值。 .dts 中使用的间隔名称与 NAND 规格没有明显的关系、我是否缺少一些有关该主题的应用手册或其他文档？

TI 是否有这款或其他类似 NAND 芯片的经验/指导？

感谢您的任何帮助。

    大家好、Giannis、

    我们没有尝试过 K2E 的不同 NAND 器件、但对另一个 Keystone-2系列器件也进行了类似的讨论。 在该线程中、它显示了 Keystone-2器件的 ECC 布局。  

    https://e2e.ti.com/support/processors/f/791/p/545410/1992122#1992122

    这是8位还是16位器件？ 如果是16位器件、是否可以尝试引脚兼容的8位 NAND？

    尊敬的 Rex：

    我们使用的 NAND 器件是 Aladery 8位。 我遇到的问题是 Linux 内核驱动程序、因为即使在 ubique.格式化之后、我也会遇到 ECC 错误和崩溃。

    我在 Linux 上做了更多的测试、擦除第一个块、在第一页上写入4096个零、然后读回它、OOB 数据使用似乎有些奇怪(文件零包含4096个零)： 

    ROOT@myboard：~ FLASH_ERASE /dev/mtd4 0 1
Erasing 256 Kibyte @ 0 - 100 % Complete
root@myboard：~# nandwrite /dev/mtd4 <零
将数据写入块0 (偏移量为0x0
root@myboard：~# nanddump /dev/mtd4 -l 0x1000 -s 0x000 -o -c

    因此、最后128个 OOB 字节(即 OOB 字节128-143)的前16个字节是非 FF、 因为只有前512B ECC 块是非 FF。 不过、nanddump 报告 ECC 读取错误、恰好在 ubibformat 之后、如 nandwrite 之后

    因此、我深入探讨了错误、发现错误似乎与 ECC/OOB 布局有关：

    • NAND 芯片支持可选片上8位 ECC、该 ECC 自动写入每页 OOB 的字节128-255。 我知道这一点、但由于它是可选的、我假设它已关闭、所以没有深入了解它。 唉……
    • U-boot 不启用片上 ECC、假定 OOB 大小为128字节(而不是实际的256字节)、并使用0-127字节内的80字节来实现由 Keyston/DaVinci HW ECC 引擎计算得出的 ECC。
    • 在 Linux 内核中、图形变得更浓：Davinci_nand.c 和 nand_micron。c 设置了 OOB 布局、但尚未检查顺序。 更具体地说明：
    • NANT_mic.c 还执行 SET_FEATURE 调用并启用 NAND 片上 ECC 计算/校验、还更新了 OOB 布局、以便为坏块标记保留的字节0-1、用户/FS 元数据可用的字节2-127、以及将字节128-255分配给 ECC (由 NAND 片上引擎计算)
    • DaVinci_nand.c 使用 nand_ooblaout_lp_ops 布局也似乎使用相同的 ECC 布局、但尝试在片上 ECC 引擎所使用的区域写入 ECC 字节、NAND 器件不允许这样做。

    Linux 内核(v4.19.59)似乎不支持我正在使用的 NAND 芯片、并且 U-boot 和 Linux 在 ECC 的使用方式中存在不一致性。 此外、DaVinci_nand.c 驱动程序可能无法与具有内部 ECC 引擎的 NAND 器件配合使用。 在这种情况下、如果 SoC ECC 引擎在这种情况下甚至有用、我不清楚、它的唯一目的是防止 AEMIF 损坏、而不是 NAND 位翻转。 在 Keystone /达芬奇 SoC 上使用8位 ECC NAND 是否有任何经验？

    我发现这个问题(NAND 片上 ECC 与 SoC ECC)在两年前就已经被问及 AM225x 器件的相关问题、并且 TI 应该最终提供解决方案、在这方面是否有任何进展？

    大家好、Giannis、

    让我在内部讨论这一点、看看我是否有信息以及 ECC 布局。

    大家好、Giannis、

    很抱歉、回答很慢。 我没有听到同事的反馈。 当我查看您的帖子时、 我怀疑 ECC 布局可能与问题有关。 在一个 TI 文档中、它描述了另一个器件的 ECC 布局、但我认为它也适用于 K2E。

    https://processors.wiki.ti.com/index.php/DM365_Nand_ECC_layout

    如果您使用的 NAND 芯片具有不同的布局、您是否认为 nand_eccla弹 出中的字段应该被相应地修改？

    尊敬的 Rex：

    虽然我不确定、但我知道需要做的是在 U-boot 和 Linux 中使用片上 NAND ECC。 毕竟、NAND 需要8位 ECC、而 K2E 只能提供4位、因此这还不够。 为此、我认为 U-boot 和 Linux 都需要调整：

    U-boot 必须在读取/写入之前启用 NAND ECC (默认情况下禁用)、并在每次读取后检查 ECC 错误、以便重写扇区或将故障页面移至另一个扇区。 这些可能应在 NAND 器件驱动程序中完成

    2.在 Linux 中，Nand_micron．c 必须在读取后检查 ECC 错误。 也许它已经这样做了、不确定。

    K2E ECC 必须被禁用(我认为 ECC-bits=0)或者被调整为独立于 NAND ECC 工作、即将 ECC 字节存储在前128个 OOB 字节中。 但是、我不清楚它能否以及如何轻松地与 NAND 特定 ECC 检查相结合。

    在我开始实施这些措施之前，我想知道另一种看法，以防有更合适的解决办法。

    大家好、Giannis、

    我不熟悉这个主题、也不能提供好的建议。 要启用片上 ECC，条目 nand-ecce-mode="hw"是否正常？ 当前的 K2E 仅支持4位 ECC、是的、需要对此进行修改。 在我看来、DaVinci_nand.c 需要进行全面修改以反映新的闪存架构。
