[Banana Pi BPI-R64] Mainline OpenWRT image

The / dev / mmcblk0p7 partition was damaged. I booted from ubuntu and ran e2fsck / dev / mmcblk0p7. I assume this situation was caused by a power outage of the router. It seems to me that ext-4 is not very good to use in this case.

Ext4 is as good as any other writable filesystem for it…you can minimize this problem by using a readonly rootfs and a squashfs overlay,but sometimes data needs to be written and powerloss may result in data corruption

It would be great to do as you said. But I don’t have the skills to do this. I have not found a good article on “how to do this”.

I’m not too. Thats why i’m still using ext4 :smiley:

I am build images with actual core 5.4.81:

Full image: https://cloud.mail.ru/public/3knc/5DpiqwZUp

Sysupgrade: https://cloud.mail.ru/public/5tpW/46L59RzHA

I just want notice that I use sata port in thise images. That mean pci-e ports dont used. Because they can’t use together.

only cn9 is blocked if sata is enabled…cn25 can be used together with sata

Hi. Do your images only have a / dev / root partition?

What you mean? I only build image. I don’t develop it.

The images are not reliable. There are no overlayfs in the images. This causes the flash memory to fail. When updating, all settings are overwritten in any case.

But we have not options becose R64 not working in 5.4 core without ext4.

because the mtd-issue? maybe a option is missing there (something with root_dev), see here

For me intresting why if I increast root dir. Router can’t run. Even if I have set 104 Mb, router is crush. Only 100 Mb.

I have try build openwrt with 493-ubi-set-ROOT_DEV-to-ubiblock-rootfs-if-unset.patch but imge don’t build, it give error.

the patch is for another board, but i guess it fixes the mtd-issue in 5.4 (but only for this board)…maybe we need to do something similar for r2 or just enable the option defined there

so just drop the patch and add option CONFIG_MTD_ROOTFS_ROOT_DEV…if it does not work i guess we need a similar approach like the patch does…but for r2/r64

Ext 4 file system work good. It have only one problem root partrition volume limit 100 Mb. If we overcome this issue, we have best firmware.

i have no idea where this limitation came from…which partiton is mounted as rootfs and how is your partition sheme (fdisk)?

Fdisk list:

The backup GPT table is corrupt, but the primary appears OK, so that will be used.

mmcblk0p5 this linux core

mmcblk0p6 FAT

mmcblk0p7 Root dir ext4

and you have resized /dev/mmcblk0p7 for your test above 100M? how did you do this?

basicly this should be work:

for the backup-error: normally a gpt writes backup of main-sector (second sector contains main information followed by more data in following sectors, first sector is mbr) to the last sector of disc. this error is shown if there is no backup-data there…but this can also be on different location because size of emmc is not equal to size of 8GB sdcard…so last sector is different

I am set root patrition volume in menuconfig target images rootfs size. This is log after boot from image with 105 Mb size root partriton.
