YAFFS2 support on NUC980 IoT SPI NAND Flash #27

Closed jaydcarlson closed 3 years ago

jaydcarlson commented 4 years ago

I'm trying to get YAFFS2 working on my NUC980 IoT dev board.

Here's my run.ini file for use with nuwriter:

image_num = 5
image0_path= /home/jay/embedded-linux/nuc980nand/buildroot/output/build/uboot-master/spl/u-boot-spl.bin
image0_type = loader
image0_exe_addr = 0x000200
image0_start_offset = 0x00000

image1_type = data
image1_path= /home/jay/embedded-linux/nuc980nand/buildroot/output/images/u-boot.bin
image1_exe_addr = 0x00
image1_start_offset = 0x100000

image2_type = data
image2_path= /home/jay/embedded-linux/nuc980nand/buildroot/output/images/uImage
image2_exe_addr = 0x0000
image2_start_offset = 0x200000

image3_type = env
image3_path= /home/jay/embedded-linux/nuc980nand/buildroot/nuc980_mtd_env.txt
image3_exe_addr = 0x00000
image3_start_offset = 0x80000

image4_type = data
image4_path= /home/jay/embedded-linux/nuc980nand/buildroot/output/images/rootfs.yaffs2
image4_exe_addr = 0x00000
image4_start_offset = 0x1600000

Here's my env.txt file:

baudrate=115200
bootcmd=sf probe 0 75000000;sf read 0x7FC0 0x200000 0x800000;bootm 0x7FC0
bootdelay=5

stdin=serial
stdout=serial
bootargs=noinitrd root=/dev/mtdblock2 rootfstype=yaffs2 rootflags=inband-tags console=ttyS0,115200n8 rdinit=/sbin/init mem=64M

Here's my kernel config:

 <*>   yaffs2 file system support
    -*-     512 byte / page devices
    [ ]       Use older-style on-NAND data format with pageStatus text
    [ ]         Lets yaffs do its own ECC
    -*-     2048 byte (or larger) / page devices
    [*]       Autoselect yaffs2 format

    [ ]     Disable yaffs2 bad block marking              
    [*]     Enable yaffs2 xattr support

Unfortunately, when I boot my system, I get ECC error messages:

Eventually, the system boots up properly, and all my files are there, but I can't create any new files (though I can edit them, it seems).

# cp mdev.conf mdev.conf.old
cp: can't create 'mdev.conf.old': Cannot allocate memory
# touch testFile.txt
touch: testFile.txt: Cannot allocate memory

Any ideas?

Hi, I think buildroot doesn't use inband-tags option to generate yaffs2 image. Please try again without "rootflags=inband-tags" in bootargs.

jaydcarlson commented 4 years ago

Actually, according to my build output, yaffs2 is doing inband-tags. Here's what buildroot prints during the image creation process:

/mnt/storage/embedded-linux/nuc980nand/buildroot/output/host/usr/bin/mkyaffs2 --inband-tags --all-root /mnt/storage/embedded-linux/nuc980nand/buildroot/output/target /mnt/storage/embedded-linux/nuc980nand/buildroot/output/images/rootfs.yaffs2\n' >> /mnt/storage/embedded-linux/nuc980nand/buildroot/output/build/_fakeroot.fs

Anyway, I tried taking out the inband-tags from the bootargs and now it can't mount the filesystem at all.

What's going on with the zillions of ECC errors I'm getting in my boot log? It looks like sometimes I'm able to modify files or even create them, but it's rare. Is there some sort of block size / erase size misconfiguration somewhere?

yachen commented 4 years ago

Hi. Can you set "erase_all = yes, run = erase" in run.ini to erase whole SPI NAND. And then program again with your setting but change "run = program_verify". Thanks.

jaydcarlson commented 4 years ago

That didn't work either, unfortunately.

Have you tried getting YAFFS2 working on your end? Do you have a different block file system you recommend for the NUC980? JFFS works, but it's very slow to mount on start-up. I haven't tried UBI, but I thought that was more optimized for bigger systems.

By default, your SDK is set up to just run everything out of an initrd image, but it'd be nice to be able to persist data across reboot cycles. What do you recommend using?

yachen commented 4 years ago

Yes. We've tested this feature (yaffs2 as rootfs on SPI NAND). Attached is our buildroot/kernel's config and env used by u-boot.

I have tried out your buildroot configuration, but I got this error while creating the image.

yachen commented 4 years ago

Oops, please try un-select menuconfig->filesystem images->"initial ram filesystem linked into linux kernel" and "cpio the root filesystem".

bernardlee99 commented 4 years ago

For the configuration that you gave, only "tar the root filesystem" and yaffs2 root filesystem" is checked. I have no idea why it is attempting to get rootfs.cpio

yachen commented 4 years ago

Can you give me the .config file in your linux-master direcotry? Thanks.

bernardlee99 commented 4 years ago

Sorry for the late response. I have switched my platform to the NUC980 Chilli Board. Can you send me a config file for Buildroot for that board so that I can try it out? I am also getting similar file system issues here.

File changes gets discarded after power off. Attempting to create a file within mounted volume gives the following error.

Hi,

The chili board config is already included in buildroot. You can use make nuvoton_nuc980_chili_defconfig to select it.

Sincerely,

Yi-An Chen

I think Bernard is talking about a chili config (SPI NOR flash) that uses YAFFS. The ZIP you provided is for SPI NAND flash.

yachen commented 4 years ago

Hi @bernardlee99,

What board are you using? This is your boot log.

m25p80 spi0.0: found w25q128, expected mx66l51235l
m25p80 spi0.0: w25q128 (16384 Kbytes)
Creating 2 MTD partitions on "m25p80":
0x000000000000-0x000001400000 : "kernel"
mtd: partition "kernel" extends beyond the end of device "m25p80" -- size truncated to 0x1000000
0x000001400000-0x000002000000 : "rootfs"
mtd: partition "rootfs" is out of reach -- disabled

And here is mine using chili config on chili board. Seems the flash on your board is only half the size. The partition doesn't fit with the SPI flash your're using. I believe that's the reason JFFS2 triggers those error message.

m25p80 spi0.0: found w25q256, expected mx66l51235l
m25p80 spi0.0: w25q256 (32768 Kbytes)
Creating 2 MTD partitions on "m25p80":
0x000000000000-0x000001400000 : "kernel"
0x000001400000-0x000002000000 : "rootfs"

Also there're some pinctrl conflict warning I'm unable to find in my boot log. You might want to make sure the kernel config matches with your board.

Sincerely,

Yi-An Chen

Hello @yachen ,

I apologize for the late response here. I have switched back to the NUC980-IoT board. Attached is my config file.

config.zip

Here's what I have attempted:

This is the parameters in my run.ini file:

run = program_verify

#------------------- program -------------------#
# type: data, env, loader, pack #
image_num = 5
image0_path= /home/bbd/Desktop/new/NUC970_Buildroot/output/build/uboot-master/spl/u-boot-spl.bin
image0_type = loader
image0_exe_addr = 0x200
image0_start_offset = 0x00000

image1_type = data
image1_path= /home/bbd/Desktop/new/NUC970_Buildroot/output/images/u-boot.bin
image1_exe_addr = 0x00
image1_start_offset = 0x100000

image2_type = data
image2_path= /home/bbd/Desktop/new/NUC970_Buildroot/output/images/uImage
image2_exe_addr = 0x0000
image2_start_offset = 0x200000

image3_type = env
image3_path= ./env-2.txt
image3_exe_addr = 0x00000
image3_start_offset = 0x80000

image4_type = data
image4_path= /home/bbd/Desktop/new/NUC970_Buildroot/output/images/rootfs.yaffs2
image4_exe_addr = 0x0000
image4_start_offset = 0x1600000

And this is the output for the given flash:

Can you perform this build's configuration on your development board to see whether similar issue persists? Thank you.

For convenience, attached is my env.txt file:

Hi,

Did you generate the rootfs with inband-tag option? You should set the rootflags as below in boot options. rootflags=inband-tags

Sincerely,

Thank you for the prompt response @yachen ,

That helped! The file write is persistent now, and the boot log is short and simple with no ECC errors anymore!

In case if others are running into this issue, with the config provided by @yachen, the run.ini file I provided above and my env.txt file(I did change sf probe to nand read too here):

baudrate=115200
bootcmd=nand read 0 75000000;nand read 0x7FC0 0x200000 0x800000;bootm 0x7FC0
bootdelay=1
stderr=serial
stdin=serial
stdout=serial
bootargs=noinitrd root=/dev/mtdblock2 rootfstype=yaffs2 console=ttyS0,115200n8 rdinit=/sbin/init mem=64M rootflags=inband-tags

This should get you up and running with persistent file storage. If you run into ECC errors, try running these in your U-boot console:

bernardlee99 commented 3 years ago

It seem that the suggested solution worked for one iteration. Upon changing things in menuconfig, I got myself into a Kernel Panic once again. However, this time even after re-cloning and using the exact same config and envs, it comes into this issue. I tried using _eraseall before the reflash. Anything I am missing here?

Here's my config file: config.zip

Hi @bernardlee99, not sure what goes wrong yet, but can you erase whole flash before program the images and see if the problem still exist?

bernardlee99 commented 3 years ago

Yes, I have used the _eraseall option, and I have scrubbed the flash using U-boot options. As a final resort, I have replaced the SPI flash IC and the problem still persists. Can you send me the image that works with your setup(images and the run.ini file for nuwriter)?
