Creating a ubifs for nand + kernel cmdline arguments

broly · April 5, 2021, 8:29pm

hello,

a few questions.

is creating a UBIFS for nand compulsory? contrasted to the situation with an SPI-NOR, it seems so. i tried to use the same approach that works for SPI-NOR (just append the squash to the image, then split) and it does not work.
i am having issues with the commandline arguments for a ubifs root. it does not seem to detect my squashfs properly. this is the output of ubinize (i am not appending the kernel, i don't see why i should?):

GagansMacPro:router Gagan$ scripts/ubinize-image.sh mipsel/images/root.fs outtest -p 128KiB -m 1024 -E 5
[rootfs]
mode=ubi
vol_id=0
vol_type=dynamic
vol_name=rootfs
image=mipsel/images/root.fs
vol_size=12149760
[rootfs_data]
mode=ubi
vol_id=1
vol_type=dynamic
vol_name=rootfs_data
vol_size=1MiB
vol_flags=autoresize

now, during kernel boot, it always says something like

ubi0: attaching mtd4
ubi0: scanning is finished

VFS: Mounted root (ubifs filesystem) on device 0:13.

obviously the file size of this partition is wrong, and so is the type of the mounted root.

could someone please help me figure out the command line arguments? this is for a DIRxx40 router. it is very aggravating dealing with UBIFS but it does seem to be simple.

right now i'm just wrapping the squash into a UBIFS and hoping that, after attaching the MTD, that ubifs will handle it.

i do note that on the OPENWRT build, it splits based on a uimage, but i don't see why this is necessary either. i am just trying to get a lean setup going. i assume the builder automates every image and so sometimes there is redundance

i've made some progress.

using the uimage mtdsplit, i now get the partitions created!

hoping this is a matter of cleaning out my cmdline arguments now!

broly · April 6, 2021, 1:47am

nope, no dice.

here is the kernel CMDLINE argument

Kernel command line: console=ttyS0,57600n8 rootfstype=squashfs

anyone have any suggestions?

is there anything i'm supposed to do before calling ubinize on the squash and appending it to the image?

everything looks aligned fine:

used the suggested patch by @firemelon:

and it gets slightly further, but now i'm seeing

        name            rootfs_data
        crc             0xdea7ad63

it boots fine with a squashfs root but, as people would expect, this is not a good idea if there are bad blocks sitting underneath (httpd performance was reflecting this phenomenon).

anyone got an idea?

i've also tried to backport weijie gao's 4.19 mtd driver

but it seems there are little niggles in the of_property calls that prevent it from being detected. has anyone else tried this?

frankly, mtk_nand2 is such hot trash. it is the hottest trash i've ever seen. it's like a fkn horrific patchwork of ralink_bbu_spi with "new" mtd code. i've never seen something so traumatising. like, why is there a static partition map at ALL? it just screams "PROBLEMS".

using weijie's 4.19 mtd driver seems like the smarter solution. doesn't seem to require much work to backport, but the of_property_get is causing issues.

as an aside, i'll note i was a serious brat when i complained about the m25p80 being too small a few years ago. i knew spi-nor was 'the best' at the time, but i didn't know why. now i do, and i underst

broly · April 9, 2021, 2:05am

i just backported the 5.4 MTD driver to 4.14 successfully (lol), yet, for some reason i'm still having problems!

CAN SOMEONE MOVE THIS TO THE DEVELOPERS SECTION? THERE HAS TO BE AN EASY FIX I'M NOT LOOKING AT.

No filesystem could mount root, tried: 
 ubifs
 squashfs

as far as i can tell, this looks correct except the failure to mount the partition after creating the ubifs, if i use the openwrt image as guide:

however it seems my build cannot detect the EOFs to automatically resize (hence why i have to manually specify ubi.mtd=4 to get as far as i have).

this shouldn't be so annoying!!

bobafetthotmail · April 11, 2021, 4:43am

disclaimer: I'm far from an expert in what is actually being done at the lower level, I have mostly experience in configuring and working with the OpenWrt buildsystem. I have added support for some devices in Kirkwood target.

Afaik jffs2 has been more or less obsoleted in favor of UBI/UBIFS even for NOR in OpenWrt. A bunch of older devices still use jffs2 but pretty much all new additions use UBI/UBIFS even on NOR.

should not be required, the build system creates the two partitions with names that are automatically detected by the kernel. Just check any other device, for example kirkwood target.

(i am not appending the kernel, i don't see why i should?):

The main reason to put everything in a UBI volume is that this way it's wear-leveled and bad blocks are managed correctly. But in most devices the uboot bootloader is unable to read UBI volumes to get the kernel and boot it so it is kept outside and flashed raw in the kernel partition or just on flash.

GagansMacPro:router Gagan$ scripts/ubinize-image.sh mipsel/images/root.fs outtest -p 128KiB -m 1024 -E 5

vol_type=dynamic
vol_name=rootfs_data
vol_size=1MiB
vol_flags=autoresize

Are you trying to generate the ubifs manually? The build system does this automatically and you should not need to care about this. You just need to specify pagesize subpagesize and blocksize (and the "-E 5" option if needed) in the device paragraph in the makefile in the images folder, for example see the one for kirkwood https://github.com/openwrt/openwrt/blob/master/target/linux/kirkwood/image/Makefile

using the uimage mtdsplit, i now get the partitions created!

Ok, so you are using mtdsplit because you don't have a separate kernel partition? you seem to be using a single partition that is called "sysv" in the uboot partition table.

but now failing to get the partition to automatically attach, with the error "no valid UBI magic":

I see that others had similar issues on another mediatek device https://bugs.openwrt.org/index.php?do=details&task_id=2097&string=mtd&order=category&sort=desc&order2=severity&sort2=desc

and from their talk it seems that this is a driver bug in mediatek devices.

Now, if you are not in the mood to try to troubleshoot the flash driver, the guy said this in that bug report

By the way the (re-)read works correctly if the ubi partition is directly defined in the .dts, so it seems that the issue hits only when ubi is a slave of firmware.

This means you remove mtdsplit and then change the nand partition list in the device dts so you permanently create a kernel partition of a set size and a ubi partition of set size. The uboot obviously won't know (nor need to know) about this, but the OpenWrt kernel will follow it and this seems to be a workaround for this driver bug.

To see how big you can make the kernel partition see the uboot's bootcommand line and see how big is the area of flash that is actually read and loaded to RAM.

as an aside, i'll note i was a serious brat when i complained about the m25p80 being too small a few years ago. i knew spi-nor was 'the best' at the time, but i didn't know why. now i do, and i underst

I can personally say that when I added support for a bunch of kirkwood devices a few years ago everything went up smooth and without a problem even if they were all using NAND, I literally just copy-pasted a few lines in the Makefile and the image was generated correctly and worked fine. I would not blame the flash technology in use.

broly · April 11, 2021, 10:49pm

hey @bobafetthotmail

thanks for your insight. i actually backported the mediatek driver and the nand driver is fine. it just seems that there is an issue with the kernel not detecting the end bytes. however i will get back to you tomorrow when i have real (leaded) solder.

i bet i am going to learn just how disastrous this tree-hugging 96%3% solder is compared to the common 63/37 SnPb. looking back at when i started soldering on a DIR-882 (this same board) almost four years ago, it is a miracle i managed to make it work.

broly · April 13, 2021, 12:37am

lol lead-free solder LICKS BALLS.
Sn63/Pb37 if you want to do it right the first time, and faster, kids.

regarding the offsets/vbtl issue: it turns out what i think happened was, after flashing openwrt the first time, my build was picking up that magic and doing something. i was under the wrong impression that the build was correctly detecting the right offset. it was not.

after doing
dd if=kernel.img of=output.img bs=4096K conv=sync

(i did not have the k before, my 882 build does not need it), the offset is now picked up correctly.

have to fix up the nvram map for the OODLES of space on Config+Config2 (on the 882 i can get 120 out of the 124k) and also accommodate this snazzy new button that's tripping resetbutton since it's not on the 882:
