DSO5102P recover not working

Hi

I've not used the oscilloscope for months and now it hang on error screen.

I tried the recovery but this fails. On the serial console I found out that the recovery
failes on restoring the root filesystem with an tarerror.

I checkethe rootfs.tar.bz:

#bunzip2 -t < /recover/rootfs/rootfs.tar.bz
bunzip2: CRC error
#

I can't find a methode to fix this problem withoutloosing anydata.
can anyone send me a rootfs.tar.bz for for the DSO5102P
Thanks
Christian

DSO5102P recover not working

Hi

I've created 3 logs

[*]Switch on the DSO which hang in boot screen. not reaction but no wonder because of kernel panic
[*]switch off and on. this time it come up with the recovery screen where I select F2recovery - recovery fail
[*]select F1 from
Hope this helps.
The code in first post is executed on the DSO console. it should explain the error with tar in 2nd log.
Thanks a lot for your help

I have feedback to the engineer to try to make a recovery file, but the previous data will be deleted. Because some files in the device are damaged. I will reply to you in time.

After unzip the attachment, put it in the root directory of the USB flash drive, insert the U disk into the oscilloscope, press F3 to upgrade, after the machine restarts, see if it starts normally, if it starts normally, run self-calibration.

Hi

restoring recoverypartition was working, but i get the same error during recovery
because of    bunzip2 CRC error for /recover/rootfs/rootfs.tar.bz

so the DSO5102P is still unusable
Please help !

1. Please confirm three files in the usb flash drive.2. The upgrade process takes about 2-3 mins.
3. After the upgrade, the oscillosope will boot on normally. Normal partition working.
Just ignore the recovery partition now. Recovery partition need to be recovered after normal partition working.
