无法将ubi附加到mtd分区 [英] unable to attach ubi to mtd partition

问题描述

我们正在基于DM365的定制板中使用MT29F8G08ABABA. 我们正在使用NAND引导. RootFS为UBIFS格式，

We are using MT29F8G08ABABA in our DM365 based custom board. We are using NAND boot. RootFS is in UBIFS format,

以下是NAND的基本结构.

Below is basic achitecture of the NAND.

我正在使用以下命令来创建ubif，

I am using following commands to create ubifs,

$(UBIFS_PATH)/mkfs.ubifs -r  $(TARGET_FS) -m 4096  -e 520192 -c 75 -o ubifs.img
$(UBIFS_PATH)/ubinize -o $(SYSTEM_CFG)_$(HARDWARE_CFG)_ubifs -m 4096 -p 512KiB $(HARDWARE_CFG)_ubinize.cfg

dm368_ubinize.cfg的内容如下，

dm368_ubinize.cfg content is as follows,

[ubifs]
mode=ubi
image=ubifs.img
vol_id=0
vol_size=37888KiB
vol_type=dynamic
vol_name=rootfs
vol_flags=autoresize

然后我使用以下命令将此ubifs放入NAND

Then i put this ubifs to NAND using following commands,

loady 0x82000000 ---> ubifs is loaded to RAM
nand scrub 0x1800000 0x2800000
nand erase 0x1800000 0x2800000
nand write 0x82000000 0x1800000 0x2800000

当我启动内核时，从内核中检测到UBIFS时出错，

and when i boot the kernel there is error while detecting UBIFS from kernel,

下面是相同的内核日志，

Below is kernel log for the same,

现在我的疑问是，为什么内核将物理擦除块大小报告为256KiB?从NAND架构来看，它看起来是512KiB.

Now my doubt is why kernel is reporting physical eraseblock size as 256KiB? from architecture of NAND it looks to be 512KiB.

对错误有任何建议/指针吗?

Any suggestions/pointer for the errors ?

提前谢谢

推荐答案

PEB大小(物理擦除块)我认为需要将其配置为ubinize配置文件的一部分，请尝试向该文件中添加以下内容:

PEB size (physical erase block) I think needs configuring as part of the ubinize config file, try adding something like this to the file:

[flash]
peb=0x20000
min_io_size=0x800
compress_type=zlib

(我的PEB大小为128KiB，因此您需要进行相应的更改). 另外，您可能会发现 UBIFS MTD页面有用-有关VID错误的问题标头偏移量. 希望这会有所帮助.

(I've got a PEB size of 128KiB, so you'll need to change accordingly). Also you might find UBIFS MTD pages useful - there's a question about bad VID header offset. Hope this helps.

这篇关于无法将ubi附加到mtd分区的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
