when writting to mtd0, Permission denied, unwritable?

My device is Pogo mobile. When I tried to upgrade its uboot, I got this error message.

Can't open /dev/mtd0: Permission denied

I read this post but it didn't help. https://forum.doozan.com/read.php?2,31358

Here are the related settings. Can anybody help me?

Ben,

You did not say which version of u-boot that you have installed on this box. But by the look of the envs, it looks like an older version of my released u-boot here.

This env is wrong:

mtdparts=mtdparts=orion_nand:2M(u-boot),3M(uImage),3M(uImage2),8M(failsafe),112(root)

There is a typo

mtdparts=mtdparts=orion_nand:2M(u-boot),3M(uImage),3M(uImage2),8M(failsafe),112M(root)

Please post output of

cat /etc/fw_env.config
fw_printenv

Do you have serial console connected? Even if not, it is still possible to to fix the error so you can install new u-boot and its env image if u-boot version is new enough.

Hi bodhi,

I can't believe I missed that typo! After fixing that, I could get uboot updated using your release. HOWEVER, my device couldn't boot after I followed your instructions to upgrade the kernel (this post, https://forum.doozan.com/read.php?2,12096).

I can connect the console using serial so here's the booting error messages and my printenv

To avoid booting problem, you should have 1 partition for the rootfs. That was mentioned in the instruction. Once it booted, set up a swap file instead of swap partition.

Try changing the devices to mmc first:

setenv devices ‘mmc usb ide’

The DTB is wrong, should be Pogo V4.

Lastly, make sure your mmc rootfs partition is labeled rootfs.

bodhi,

The problem is now that I can't get it to boot. If we can figure out how to boot it, I think I can easily fix those errors. I tried

setenv devices ‘mmc usb ide’

but it didn't work. In my understanding of the booting message, there's an error preventing the device from locating the SD card. Can you find where to change the setting to let it see the SD card?

My root is labeled as rootfs but I neglected the swap partition. BTW, the device could boot up after loading your new uBoot but failed when upgrading to the new kernel. I must have done something wrong when following that instructions....

Thanks a lot!

I guess I should fix the SD card by changing it to be a single partition, and then it will probably work, right?

I changed the SD partition to a single one. but still saw the similar error message as follows.

Ben,

Yes, the rootfs is most like the reason. But the DTB file name is wrong, too. Here is what you need to do.


1. Recreate the rootfs, and make sure you follow the instruction closely.
2. Attach the rootfs to the box, power up.
3. Interrupt serial console at count down, and execute

setenv devices mmc
setenv dtb_file ‘/boot/dts/kirkwood-pogoplug_v4.dtb’
printenv
boot

And then post the entire serial console log here.

bodhi,

If I can't boot, how can I recreate the rootfs? Recreating it needs to be done on the device, right? Can we do that on other device/linux like across compiling? I'm not good at the embedded linux OS, please advise. Thanks!

bodhi,

Please ignore my last question. I'm working on the rootfs and will get back to here soon.

Hi bodhi,

I used a new SD card, formatted it to a single ext3 partition with "rootfs", and then closely follow the instructions about creating roofts (the section of "Updated 24 Jul 2017:" ) at the post https://forum.doozan.com/read.php?2,12096, where I used the Debian-4.12.1-kirkwood-tld-1-rootfs-bodhi.tar.bz2 to recreate the rootfs.

And then I attached the SD card to my pogoplug mobile, ran the commands as you instructed. That is "setenv devices mmc", "setenv dtb_file ‘/boot/dts/kirkwood-pogoplug_v4.dtb’ ", and "printenv" and then "boot"

I got this error message

BTW, I created the rootfs using a pogoplug E02. I skipped step 4 (Create uImage with embedded DTB) when creating the rootfs because I had installed your latest UBoot on the pogoplug mobile.

I see. Your envs are not good to boot from mmc automatially.

You did not flash the default envs image when you went through the u-boot installation.

Quote

8. Flashing default u-boot envs image (if you are upgrading from 2016.05-tld-1 u-boot, you can skip this step 8).

As described in step 1, u-boot envs must be defined in /etc/fw_env.config as

# MTD device name Device offset Env. size Flash sector size Number of sectors
/dev/mtd0 0xc0000 0x20000 0x20000

This default envs image supports booting with multiple disk drives (and hubs) attached. The disk drives could be any type (usb, sata, sd card). The scanning logic and default envs were set to automatically boot the box with the following required configuration:

For whatever reason, if you can't set up your configuration to satisfy the following 4 requirements, then don't flash this defaut envs image. It might not boot properly. In this case, section C below can be used to tailor the envs to your specific configuration.

r1. There must be only one partition among all partitions from all drives that contains the kernel files. The 2 kernel files are /boot/uImage and /boot/uInitrd.
r2. The partition that contains the 2 kernel files must be partition 1 in a disk drive
r3. The partition that contains the rootfs must be labeled rootfs
r4. The rootfs partition is recommended to be type Ext3 (this is not a hard requirement, ext4 should boot OK, but Ext3 will ensure no problem).

So the bottom line is if you have only one rootfs in a single Ext3 partition, which is labeled as rootfs, then you're all set.

a. Download the default u-boot envs at Dropbox:

uboot.2016.05-tld-1.environment.bodhi.tar
md5:
3823eef10011b864859d31a76470e0e3
sha256:
c8db95a4225e8d78bdaaaa372bd5a87e4b98f3448dd9c62fc96c72b2df1a997c

This tarball includes 3 files:

uboot.2016.05-tld-1.environment.img (the default envs image to be flashed)
uboot.2016.05-tld-1.environment (the content of the default envs in text format)
uboot.2016.05-tld-1.environment.64K.img (small envs image to be flashed on HP T5325 only).

b. Extract the archive to /tmp
cd /tmp
tar -xf uboot.2016.05-tld-1.environment.bodhi.tar

c. Save current envs with fw_printenv, or just copy/paste the listing into a text file.
fw_printenv > current_envs.txt

d. Flash u-boot envs to NAND location 0xC0000.

Be extra careful with the next 2 commands, you should see output that look like below. If there is error, then do not reboot, post your problem here so we can help.

/usr/sbin/flash_erase /dev/mtd0 0xc0000 1
Expected output:
Erase Total 1 Units
Performing Flash Erase of length 131072 at offset 0xc0000 done

/usr/sbin/nandwrite -s 786432 /dev/mtd0 uboot.2016.05-tld-1.environment.img
Expected output:
Writing data to block 6 at offset 0xc0000

e. Modify the following u-boot variables using fw_setenv:

Note that arcNumber and machid are not necessary if you are booting with FDT kernel 3.17+ in the latest kernel and rootfs thread. But it does not hurt to set them anyway.

archNumber and machid are required for non-FDT kernel (3.16.x or earlier)

Also note that only some boxes need machid, some don't (so the command fw_setenv machid below clears them).

for Pogo V4/Mobile:
fw_setenv arcNumber 3960
fw_setenv machid f78

for iConnect:
fw_setenv arcNumber 2870
fw_setenv machid

for Stora:
fw_setenv arcNumber 2743
fw_setenv machid

for Dockstar:
fw_setenv arcNumber 2998
fw_setenv machid

for Pogo E02:
fw_setenv arcNumber 3542
fw_setenv machid dd6

for GoFlex Home:
fw_setenv arcNumber 3338
fw_setenv machid


for GoFlex Net:
fw_setenv arcNumber 3089
fw_setenv machid

for Sheevaplug:
fw_setenv arcNumber 2097
fw_setenv machid

for NSA325:
fw_setenv arcNumber 4495
fw_setenv machid

for NSA320:
fw_setenv arcNumber 3956
fw_setenv machid

for NSA310S/320S:
fw_setenv arcNumber 4931
fw_setenv machid

for NSA310:
fw_setenv arcNumber 4022
fw_setenv machid


Then for all boxes, restore these 2 envs using the saved envs text in step c (replace xxx with the real saved values)
fw_setenv mtdparts 'xxxxxxxxx'
fw_setenv ethaddr 'xx:xx:xx:xx:xx:xx'

Note: for boxes that boot with SATA as rootfs. Please make this adjustment if your boot drive is SATA:
fw_setenv bootcmd_uenv 'run uenv_load; if test $uenv_loaded -eq 1; then run uenv_import; fi; sleep 3'
(This will help the "ide reset" to work properly. There seems to be a bug in u-boot that if you do "ide reset" too quickly in succession, the SATA drive might have problem spinning up).

f. Adjust the DTB name to boot with a rootfs that has FDT kernel 3.17+ (this is the normal case):

Find your box DTB file in the rootfs /boot/dts directory and adjust the env to it. For example, if the box is the Dockstar
fw_setenv dtb_file '/boot/dts/kirkwood-dockstar.dtb'

In the special case when you are booting with a non-FDT kernel 3.16 or earlier, or if you have appended the DTB to uImage. Remove the DTB file env. If not sure please post question before continuing.
fw_setenv dtb_file

h. For sanity check, list you envs again
fw_printenv

If there is error in listing u-boot envs, stop here and post your problem so we can help.

Remember to save away your old envs text file created in step c for future reference in case more need to be restored.

i. Done step 8.

Your current envs is set up to boot with USB drive only (yours were the old default envs before u-boot-2016.05-tld-1)


See here how to load the latest default envs script at u-boot prompt:

https://forum.doozan.com/read.php?3,29362,29390#msg-29390

And since you have the Pogo V4 and want to boo twith MMC these setenvs in that post should be adjusted (replace xx:xx:xx:xx:xx:xx with your real MAC address)

from

setenv devices 'usb ide'
setenv ethaddr xx:xx:xx:xx:xx:xx
setenv dtb_file '/boot/dts/kirkwood-goflexnet.dtb'
boot

to

setenv devices 'mmc usb ide'
setenv ethaddr xx:xx:xx:xx:xx:xx
setenv dtb_file '/boot/dts/kirkwood-pogoplug_v4.dtb'
boot

Hi bodhi,

Super! It's working now :D although it's not exactly the same as you described for loading Envs at Uboot prompt. That post still described how to load Envs using USB but mine is MMC (SD card) so I had to plug it into a SD card reader and plugged the card reader to the USB port. After that, "ext2load usb 0:1 0x800000 ...." could run but "source 0x800000" complaint about "wrong image....". After that, I realized it may be able to boot up directly using the USB SD card since you said the wrong Uboot Envs supported USB booting only. My guess worked it booted up via the USB card reader. After that, the thing turned a lot easier.....

After I installed everything, including the latest kernel, I just noticed a message when it's booting as below

[....] Waiting for /dev to be fully populated...[   28.736136] marvell-cesa f1030000.crypto: CESA device successfully registered
[   28.778489] orion_wdt: Initial timeout 25 sec
done (timeout).

Is that something I should be concerned? But the device can boot up and I can log in as usual.

You take paypal donation? I'd like to buy you a cup of beer or something. I guess many people thank you the same way. If you like drinking, you might get drunk everyday xD.

I haven't touched the little things (I have 4) for years. This time it really refreshed my memory about its setup/installation.....

Thanks a lot!

That's even better than loading uenv script solution!

Sometime the SD card is very slow responding. You can ignore this message.

I drink, but only get drunk a few times a year :D. Donation is not necessary. But if you'd like, see bodhi's corner in my signature.

Boot back to sysvinit, do apt-get update/upgrade. And then switch back to systemd.
