So ...
Stock ubot & envs are inside ..
and LAN work ... :)

but, it is not so easy, as it seems to be..

For the first time, I will try back serial uboot, from mtd3 image via flash-write command.
No success, verify failed.
Then try to flash from original HP Uboot update file, and still no "happy end" ..
..and after reboot, I have "one nice piece of electo-garbage" .. oh yes, it is bricked...

We started "rescue mission" ....
Desolder flash, read images from working one, split it ... and try to flash via programer.
..but...
Desoldered flash is not accessible or read&verify errors ocured.
We try to erase it. After two (or three) forced retries, we have accessible flash.
After this "procedure", we have fully accessible, readable and writable flash ..

(yes, It is strange ..)

Hey. When I try to update Uboot, the following errors occur.

[root@router]~# flash_unlock /dev/mtd3
flash_unlock: error!: could not open: /dev/mtd3
              error 13 (Permission denied)
[root@router]~# flash_unlock /dev/mtd0
flash_unlock: error!: could not unlock device: /dev/mtd0

              error 95 (Operation not supported)

What could be the problem?

WMLex,

I have only provided installation instruction from stock OS. Try booting into stock OS and install from there.

Not a lot of people have this device, so nobody has remined me to write section B :) It is possible, I just need to refresh my memory again and write it.

Quote

A. Installation from stock OS

Prerequisites

The Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi.tar.bz2 rootfs must be prepared in advance on a USB drive on a single Ext3 partition and already mounted in this box before starting installation. The installation steps below assume that the following 4 prerequisites have been met:

a. The rootfs was extracted as is, and step 4 in the Debian rootfs installation is skipped (since we are going to boot with new u-boot, don't append DTB to uImage).
b. The tarball uboot.2015.10-tld-2.t5325.bodhi.tar has been downloaded and place in the /boot folder of the USB rootfs
c. The USB rootfs will be the only USB drive mounted in the T5325 box.
d. The installation must be done while stock OS running.

Steps:

1. Boot into stock, mount the Debian rootfs, extract u-boot images

mkdir /tmp/sdb1
mount -o noatime /dev/sdb1 /tmp/sdb1
cd /tmp/sdb1/boot
tar -xf uboot.2016.05-tld-1.t5325.bodhi.tar
tar -xf uboot.2016.05-tld-1.environment.bodhi.tar

2. Save your current u-boot envs and backup your current stock mtds for future restoration, should you decide to go back to stock

cd /tmp/sdb1/boot
fw_printenv > current_envs.text
dd if=/dev/mtd0 of=t5325.mtd0 bs=64k conv=sync
dd if=/dev/mtd3 of=t5325.mtd3 bs=512k conv=sync

3. Verify the MTD flash definition in your running stock OS. Note the mtd0 and mtd3 definition, they must be identical to your current mtd0 and mtd3.

cat /proc/mtd
dev: size erasesize name
mtd0: 00010000 00010000 "u-boot env"
mtd1: 00010000 00010000 "permanent u-boot env"
mtd2: 00010000 00010000 "HP env"
mtd3: 00080000 00010000 "u-boot"
mtd4: 00040000 00010000 "SSD firmware"

4. Flash u-boot to mtd3

cd /tmp/sdb1/boot
flash_unlock /dev/mtd3
flashcp -v uboot.2016.05-tld-1.t5325.mtd0.kwb /dev/mtd3

Expected Output

Erasing blocks: 8/8 (100%)
Writing data: 512k/512k (100%)
Verifying data: 512k/512k (100%)

If there is any error, stop here and post for help in recovery

5. Flash u-boot default envs to mtd0.

cd /tmp/sdb1/boot
flash_unlock /dev/mtd0
flashcp -v uboot.2016.05-tld-1.environment.64K.img /dev/mtd0

Expected Output

Erasing blocks: 1/1 (100%)
Writing data: 64k/64k (100%)
Verifying data: 64k/64k (100%)

If there is any error, stop here and post for help in recovery

6. And add fw_env.config to your stock OS. And then reference your saved current_envs.txt in step 2 to restore box specific info in u-boot envs.

a. Add fw_env.config to your stock OS.

echo "/dev/mtd0 0x00000 0x10000 0x10000" > /etc/fw_env.config

b. Modify envs and also setup netconsole. Replace xx below with your box specific settings.

/tmp/sdb1/usr/bin/fw_setenv arcNumber '2846'
/tmp/sdb1/usr/bin/fw_setenv mtdparts 'mtdparts=spi0.0:512K(uboot),256K(sdd_firmware),64K(uboot_env),64K(permanent_uboot_env),64K(hp_env)'
/tmp/sdb1/usr/bin/fw_setenv ethaddr 'xx:xx:xx:xx:xx:xx'
/tmp/sdb1/usr/bin/fw_setenv devices 'usb ide'
/tmp/sdb1/usr/bin/fw_setenv dtb_file '/boot/dts/kirkwood-t5325.dtb'

Setup netconsole envs (to activate later in Debian).

/tmp/sdb1/usr/bin/fw_setenv preboot_nc 'setenv nc_ready 0; for pingstat in 1 2 3 4 5; do; sleep 1; if run if_netconsole; then setenv nc_ready 1; fi; done; if test $nc_ready -eq 1; then ./run start_netconsole; fi'
/tmp/sdb1/usr/bin/fw_setenv ipaddr 'xxx.xxx.x.xxx'
/tmp/sdb1/usr/bin/fw_setenv serverip 'xxx.xxx.x.xxx'

c. Remove envs

/tmp/sdb1/usr/bin/fw_setenv mtdids
/tmp/sdb1/usr/bin/fw_setenv partition
/tmp/sdb1/usr/bin/fw_setenv machid


7. Done.

Upon reboot, on serial/net console, u-boot banner should show

U-Boot 2016.05-tld-1 (Jun 12 2016 ….)
HP Thin Client T5325

B. Installation from the latest Debian rootfs

TBD.

This problem usually is not because of the new kernel or Debian version. It is usually because you might have not synched the disk before reboot, or the roofs filesystem was corrupted.

Please describe how did you create this rootfs, and which kernels have been installled in this rootfs since you created it, and what procedure used in doing that. Even better if you can post the entire log of what you done.

WMLex,

Ah! I see that you're not familiar with kernel installtion procedure.

The full GNU/Linux system includes a rootfs and a kernel installed on that rootfs. The USB partition that you're booting with must contain a rootfs. And then it's up to you to install a kernel to run inside that rootfs. Or if you use my rootfs (Debian-4.4.0-kirkwood-tld-1-rootfs-bodhi.tar.bz2) then the custom 4.4 kernel is already installed inside this rootfs.

You've download uImage and uInitrd only, but did not install the full kernel. For example, this is the installation command to install one of my customed kernels:
dpkg -i linux-image-4.8.0-kirkwood-tld-1_1.0_armel.deb
You can also run the Debian installer to install a mainline kernel (without patches as in my customed kernel).

When you download the uImage and uInitrd only, then sometime it will work. But a lot times it will not. Because the kernel headers might be different between versions.

WMLex,

1. Make sure you followed the instruction to create the Debian 4.4 rootfs very closely (being root, label the partion name as rootfs, single ext3 partition...).

2. If after verifying the rootfs creation, it still got stuck as above, try using a different thumb drive.

..so ...
is BTRFS supported ..?? .. in your kernel ..??

cause I have one box with debian, 32Mb Boot EXT2 (due to uboot)
and all other space on stock flash as BTRFS (aprox 460Mb)..
no thumb drive is needed..

Is there any way to unbrick a T5325? I issued a fw_setenv command from my completed install (bodhi's 4.4.0), and the device no longer brings up uboot. I confimed my cable setup works, as I have another T5325 that still brings up uboot and bootstraps properly. I'm wondering if I might've corrupted /dev/mtd0 by chance. I've spent the last 2 days lurking and reading on the forums (this and others) before posting something.

Sure, you can connect serial console and use UART booting (loading u-boot using kwboot) to boot the box.

Download u-boot:
http://forum.doozan.com/read.php?3,12381

UART booting:
http://forum.doozan.com/read.php?3,7852,7852

If you have installed my released u-boot image and you think only the u-boot envs are messed up, you can use uEnv.txt capability to restore. No serial console is needed in this case.

The above was OK. It's normal because u-boot was scanning all drives.

This is interesting. The driver seems to dislike something about this SATA interface.

If you are booting only with internal flash, then you can set devices to ide only, to not seeing the usb scans

Re: HP T5325 Thin Client Debian

All,

I've gone back to older kernels to track this network problem in Debian. This problem (only exists in the HP T5325) is mainly because a wrong link speed (1 Gbps) was identified by the driver, while this box NIC is 100Mbps.

This problem requires us to work around using either 1 of 3 methods:

1. Unplug the ethernet cable and replug it in to get network connection at the correct link speed.

Or,

2. Run ifup/down to force the network to renegotiate the speed.

ifdown eth0
ifup eth0

Or,

3. Add these to your /etc/rc.local (recommended solution):

logger -s -i "Run ethtool to set link speed to 100Mbps"
/sbin/ethtool -s eth0 speed 100 duplex full


Most likely, a maintream network driver patch has inadvertenly changed the behavior of autonegotiation (which affects this box only). Kernel 4.10.9-kirkwood-tld-1 was the last one that we did not have this problem for HP T5325. So you could either work around using one of the 3 methods above, or downgrade to kernel 4.10.9-kirkwood-tld-1.

I'll see if I can patch it to get it working and include it in the next kernel release (I'm still waiting for a security patch to get to mainline).

I have fixed this network problem in u-boot proper and released a new version U-Boot-2017.07-tld-1:
https://forum.doozan.com/read.php?3,26562

The link speed 100Mbs is now set during u-boot booting. So we don't need to rely on Linux kernel to renegotiate the link.

JRD,

Please post the entire serial console boot log here.

Also in Debian after login with serial console, get the listing of u-boot env and post here, too.

fw_printenv

Note: with the new u-boot 2017.07 version, you don't need to use the work around using ethtool anymore (it won't not hurt to do that, though).

JRD,

Following the instruction and flash the u-boot image and its default envs image. You will be able to set the MAC address.

OK,

but I have not enough time at this moment...

MTD flash is not accessible with "new Debian distro" (fresh installed SATA SSD)
and with your's Debian FS version also.

..some time is needed ... to test it ...

For kernel 4.13.5-kirkwood-tld-1 there appear to be issues with the kirkwood-t5325.dtb as the /proc/mtd has the permanent u-boot env listed twice:

Also it appears that mtd0 cannot be unlocked:

Something is wrong in your system. I did not see this.

You clearly must be using a previous version of the kirkwood-t5325.dtb file as a hexdump of that file distributed with both linux-4.13.5-kirkwood-tld-1 and linux-4.14.1-kirkwood-tld-1 shows the 'permanent u-boot env' twice and never mentions 'hp_env' at all.
