[fremen67]

Everything done !!, the oscilloscope is now working !!!. 

Awsome job fremen67 !!. Thanks a lot to You, Lauris and KL27x !!.

Hehe you are coming back from very far 
Without Lauris' backup it would have been impossible to help you.

Starting kernel ...


What you see now before the kernel is loaded is the way Hantek has implemented the recover mechanism.

The whole "misc" partition is used as a flag !! The bootloader reads it, if the first byte is not null, then it erases the partition, load the kernel and starts.
The firwmware is supposed to write to the first byte of this partition on normal stop of the MSO. If something goes wrong it won't, then on next reboot, the partition will still be empty and the bootloader will then boot on the recovery partition which allows you to choose to rebuilt the kernel and rootfs partition from backup.

If you manually starts with the recover partition (from bootloader), you will be able to backup kernel&rootfs Inside the recover partition... that's what was not done on Lauris' MSO. Hantek should have done that at the factory. Should a problem happen, the recovery would be useless.

The principle is good but the way it is written is far from being clean... They have shared the sources as uboot is GPL licenced. Just look how they modified the original code. There are still useless test lines Inside (reading back the partition after erasing it for nothing) :

Code: [Select]

int fs_test()

char flag = 1;
char cmdBuf[100];

Ok, now wait one second. you are saying that I'm sitting on ticking bomb too? Any way to prevent that? Since for me scope is not yet that clear as PC, so I would like to have working recovery for it.

It's a good idea for recovery solution after an upgrade. But if they don't put a verification routine inside the firmware script, this recovery didn't work. Like my case, the upgrade routine has finished with sucessfull, but it's make a complete mass in the rootfs.

Lauris

Well, it's not really a ticking bomb. Your MSO has a new layout which would allow a simple recovery of its system when needed. It's just that this recovery would not work, not that you will have problems. Daniel's problem was that he upgraded his "4 partitions layout style" MSO with a script that was made for the new "8 partitions layout style" MSOs and which destroyed the rootfs partition...

All you have to do is to launch yourself the backup process and you will be good.
When the MSO boots in recovery mode, it shows for 10 seconds a screen where you can read:
"Press F1 to reboot the system"
"Press F2 to recover the system"
"Press F3 to update the recover partition"
"Press F4 to backup the system(For developers)"

The last option (F4) only appears if the initial backup is not on the recover partition (which should be your case). It's also a way to know wether you have to do this backup or not.

If you don't do anything, the MSO will reboot the normal way.

So you have to press F4 within10 seconds and the MSO will starts its backup (the one Hantek should have done at the factory). This is quiet long, it will last for some minutes.... and that's it!

You can enter the recover menu via the serial console by stopping the bootloader and choosing the correct option... or you can use the attached "update" script which will force the MSO to boot in recovery mode once (If you are not quick enough, just do it again )

Edit: once your are done, I would advice that you run once again the backup script I posted (the last you used) so that you have an uptodate backup of your system with you... I find it saver to have a backup outside the MSO.

You MSO had no recover partition when you run the update. That's why it failed (and of course because the script did not check on what kind of MSO it was running). Now the next updates should works as it is now uptodate.

Is there a way to make this backup, and leave it on the right partition ?.

Yes, you can access the recover menu from the bootloader or via the script I just posted and run the backup from there.
But anyway, should you have another problem, you now have all the Tools and backups to handle it 

[dtomazini]

That is right !! 

[mg.glodek@gmail.com]

Hi,

I think that I have very simmilar problam that dtomazini has. I will be really greatfull if You could help me with comming back to life my Voltcraft DSO-1062D. This is the copy of the Hantek/Tekeway scopes, uses same firmware.

The scope I have received crashes at the very begining after start, shoving only Volcraft logo. After connecting via UART to my laptop with Putty software I have noticed that linux faild to start with "Kernel panic - not syncing: Attempted to kill init!" error.
Full log below.

Can I ask You to help me solving the problem? What I shold repair/upload using boot menu? I think that botloader is working corectly as I can go to boot menu and probably make use of DWN upload method (didn't tasted as i do not have tq2416 driver required for that connection).

Kernel panic - not syncing: Attempted to kill init!
g_serial gadget: high-speed config #1: Generic Serial config


[fremen67]

Hi,

I think that I have very simmilar problam that dtomazini has. I will be really greatfull if You could help me with comming back to life my Voltcraft DSO-1062D. This is the copy of the Hantek/Tekeway scopes, uses same firmware.

The scope I have received crashes at the very begining after start, shoving only Volcraft logo. After connecting via UART to my laptop with Putty software I have noticed that linux faild to start with "Kernel panic - not syncing: Attempted to kill init!" error.
Full log below.

Can I ask You to help me solving the problem? What I shold repair/upload using boot menu? I think that botloader is working corectly as I can go to boot menu and probably make use of DWN upload method (didn't tasted as i do not have tq2416 driver required for that connection).

You would need a backup from the same DSO or at least from a similar one like a Hantek DSO5062D, DSO5102D or DSO5202D.
You may find someone who could post one for you if you ask in this thread:
https://www.eevblog.com/forum/testgear/hantek-tekway-dso-hack-get-200mhz-bw-for-free/
With that backup, I could create a root.ubi file that you will be able to flash on your DSO.
The kernel seems to load correctly and the problem seems to be related to the Rootfs partition.
What kind of OS do you have on your PC? Win7 x32, Win7 x64 ...?

[mg.glodek@gmail.com]

Thank You for quick answer. I have Win7x32 and Win7x64 on the other computer. I have just post a reqest on the topic You have mentioned.
Can I ask You to look on the http://voltcraftdownload.info/Default.aspx?modelno=DSO-1062D site? There is a Source Code (GPL2.0) for my scope (>300MB). Is this something that we can use?
Can You please indicate where can I find propoer USB driver for DWN (tq2416 driver)?

You won't find something usefull in those GPL sources for your problem.

You will find DNW and the tq2416 drivers here for Win7x32:

Thank You for the links.

In the meantime I have received some DSO-1062D dump file from someone who have seen my post on the second topic. As this file has only 4 MB I do not know if this is something that I can use or should I ask for whole backup?

This is a dump from the kernel. I would bet the partition which is corrupted is the last one (mtd3=rootfs).
If this kernel dump comes from an identical machine, you can try flashing it to yours and then you will be sure but as you usually don't write on this kernel partition, there are few chances that it gets corrupted.

As I do not have any Linux experience can I kindly ask You to briefly describe how to do that flash? I know that I can do it via DWN but do not know any details.

1 - Stop the boot process of your device by pressing space key when connected vi serial console (you will get the uboot menu shown in the previous posts)
2 - connect your PC to DSO vi USB
3 - choose "t" option (test linux image)
4 - install drivers on your PC
5 - launch DNW and send a small file (your kernel backup f.e.). It is just to test DNW, nothing will be written on the DSO flash.

If everything is OK (you will see dashes on your serial console if it works), you can do it again but this time select the kernel option (3?) and send your kernel backup.
That's it!
PS: read again this thread, this should help also...

[mg.glodek@gmail.com]

It is finally working. You had right that it was a problem with kernel. DSO started after kernel test (t from boot menu) but than I had to flash with 3-rd boot option to make this change permament.

Thank You very much for the support. I hope that it will never happen once again.

I have accidentally overwritten my root partition and need to flash a backup dump. But is has the wrong format.

How is it possible to transform a dump file (root.bin) into a flashable root.ubi?

ok. figured it out:

1) install ubi_reader from https://github.com/jrspruitt/ubi_reader
2) extract root.bin nanddump backup file with "ubureader_extract_images -l root.bin"
3) the resulting ubifs file "root.ubifs" is the correct format to flash
4) use option 5 ("Download UBIFS image (root.ubi) to NAND flash") in u-boot on hantek
5) restart scope

... boom ... scope works again

Can anyone point me to a walkthrough for recovering this oscope via JTAG?

I had a bad update, which got fixed. Since I was all set up, I decided to poke around a bit and messed up the system again. No problem, I have all the tools ready to go...
Here's the stupid part...  I was flashing the partitions back, via the bootloader and somehow hit "A"(which is for uploading a program to the full chip) instead of "7"(for uploading the recovery partition). Unfortunately, I didn't notice this error until after I sent the recovery image. This is a very bad thing...

So, now I get no output from the serial port, no backlight, and all of the buttons light up.  I have a backup of my system, but I am not sure how to proceed with recovering via JTAG.
Luckily, I have been wanting to learn about JTAG for awhile, so have a few programmers on hand and understand the very basics, but not much more.  I went ahead and soldered in a set of header pins on J901 (which I believe is the JTAG port). I have tried talking to the board with openocd, but with no luck.  I am getting the following error message:

Hello:
You have got the flash file for the dso-1062d?.

[hasjon]

Hi All

I have been reading this post and I'm hoping that someone could help.

Please see the attached pictures.

I have successfully made serial connection with my Hantek DSO5102P,  via USB to serial and the direct USB connection.  Attempted to reflash.  However after the reflash, the oscilloscope hangs after the reboot.  Upon power up, the Hantek logo displays and after that nothing happens.

Please see the attached screens shots from 'EmbedSkyDownLoadTool_V1.0'' and the terminal Running Information after transferring the file 'wh5   root_dso5102p3.ubi'.

I believe I may have the wrong .ubi file.  I may have a partition error and thus would also require a working backup from another DSO5102P.  Please can someone provide a backup and help to convert to the correct .ubi file so that I can attempt a successful firmware reflash.

Thank you

[krisfromhell]

hi

ist it possible to get the dump file for the "voltcraft dso 1062d" too. i need to restore it

[R4T]

mg.glodek I am also trying to repair a DSO-1062D (that has never worked) and I suspect I have a very similar problem to the one you had - it hangs in a slightly different place but with a similar message. Please may I have access to the kernel dump that you used?  Thanks!  Richard
