File System Error...can not boot

[kalux]

Followed the pin29 procedure to root my hub.... executed setenv .... command.. that was ok I believe. After executing "nand read ${loadaddr} app-kernel 0x00400000 && bootm ${loadaddr}".
After this executes, it shortly stops... the results are as follows:

Code: Select all

=> nand read ${loadaddr} app-kernel 0x00400000 && bootm ${loadaddr}

NAND read: device 0 offset 0x2b00000, size 0x400000

the hub displays a white light.

Any suggestions and specific instructions would be greatly appreciated!

This exactly happened to me, but because it is late in the night, I did only this brief investigation. Tomorrow I will try to find more (if I will have time).

Yours and mine root filesystem on mtd5 aka gpmi-nfc-general-use gets corrupted. The reason for this is unknown. To find out I will need a brief history of your Wink Hub, because this may be related to 2015-04-SNAFU.

What you can do is boot into updater using this command in your bootloader:

Code: Select all

=> run boot_updater


Log in (root & empty password), and once there, you can try to mount it manually. However it would probably not work. But give it a try:

Code: Select all

mkdir /tmp/work/
ubiattach -p /dev/mtd5
mount -t ubifs ubi2:rootfs /tmp/work/


If it gets mounted successfully, than it means filesystem get repaired (on mount) and next boot should be fine.

If mount failed like this, then, well, we have a problem:

Code: Select all

[root@flex-dvt ~]# mount -t ubifs ubi2:rootfs /tmp/work/
UBIFS: recovery needed
UBI error: ubi_io_read: error -74 while reading 106496 bytes from PEB 401:24576, read 106496 bytes
UBIFS error (pid 5150): ubifs_scanned_corruption: corruption at LEB 583:45056
UBIFS error (pid 5150): ubifs_recover_leb: LEB 583 scanning failed
mount: mounting ubi2:rootfs on /tmp/work/ failed: Structure needs cleaning


What makes this situation especially difficult is that there is no file-system recovery for UBIFS. So no fsck.ubifs, see this thread:

http://lists.infradead.org/pipermail/li ... 57710.html

What I am thinking could work is to re-create clean partition and run upgrade process, which will pretty much recreate content. But I am not sure if everything would be recreated. If not, then we need to create that damn mtd5 from mtd2. Or someone here could be so kind and provide mtd5 image. There are definitely few some options.

If you can boot into the updater partition, then go straight to the upgrade. The upgrade doesn't pick and choose what files to update, it actually wipes out the entire partition replacing it with a new one. So updating the primary from the update boot should get you going.

If it thinks you are already current, change the cf_ files in /database to an older version so it will think you need an update.

If your updater partition is pre-snafu, update the bottom of /root/platform/updater.config (from memory, may not be exact name) at the bottom where it sets the curl arguments and ADD --insecure

[CloneNum3]

I have most of the various images... Root, updater, kernel, etc... Ranging back to the early days. I even have the beta, staging, and other random non-production ones too.

If anyone wants a hub that follows the beta or staging, I'll list a rooted hub on eBay for you the way you want it.

Just a quick update, that all the instructions in your post worked like a charm. Thank you!

Yes, when it is pre-SNAFU, it is bit more difficult, but definitely doable. Still better than shipping Wink Hub to factory -- saving some shipping costs for Wink, hope they appreciate:)
