VOLTCRAFT DSO-1084E (Hantek DSO4084B) stuck at boot screen

[Oscillator]

thanks for the "normal" boot log.

thats great!   

i noticed already before that in your boot log there is one partition missing:  "config"

i am not sure if this is related to different firmware versions, but most logs look like this:

Creating 9 MTD partitions on "NAND":
0x000000000000-0x000000100000 : "uboot"
0x000000100000-0x000000180000 : "params"
0x000000180000-0x000000380000 : "logo"
0x000000380000-0x000000400000 : "misc"
0x000000400000-0x000000800000 : "kernel"
0x000000800000-0x000003a00000 : "rootfs"
0x000003a00000-0x000004e00000 : "config"
0x000004e00000-0x000005200000 : "kernel_bk"
0x000005200000-0x000008000000 : "recover"

okay, i didnt want to wait any longer and connected my scope to the serial bridge.

my logs look very similar to the logs from ubata.

i dont have a "config" partition too.

@ubata:

how did you write your sd-card?

- which windows version?
- which software?

i tried today without any success.

but i figured out how to transfer files from PC to the scope in usb download mode!

first you need this software:

SMDK2416.zip

it contains drivers for 32bit. it was working for me on win 7 32bit.

here are drivers for 64bit (but untested, refused to install on win 11 because of missing driver signature):

driver_x64.zip

start dnw.exe on the PC and make serial console settings first and then open a serial connection.

when you are in usb download mode you might press "t" for "Test Linux Image (zImage)"

then you are told to connect the scope to the PC with an usb cable. after plugging the cable windows wants to install the device driver for the scope.

finish the driver installation and go back to dnw.exe. now you can select "transmit" in the usb menu. select your kernel.bin file which comes with the hantek sd-card.
after sending this file to the scope the kernel.bin will be booted.

this is just for testing the whole setup.

if everything is working fine, you might send the individual files from the hantek recovery sd-card.
but dont send the uboot.bin! this can brick the booting of your scope!

but use flashing the NAND at your own risk!  i didnt try yet. ,-)

[Oscillator]

the day of success!!!





today i made the big step of flashing parts of the NAND.

according to my theory of my previous posting  i was using "dnw.exe" and some flash files from
the hantek recovery sd-card for flashing in usb-download mode of the scopes bootloader.

so i have flashed rootfs.ubi, recover.ubi and kernel.bin to the NAND. now my scope is booting fine again. 
 
and a nice side effect: it turns my OEM branded KKmoon DSO4102S into a Hantek DSO4202C.
so now i am able to get some firmware updates too! 

this is the boot log of the broken scope before flashing:

so there is still no extra "config" partition like in other firmwares but who cares?

@Oscillator:

Thank you for your contribution. Flashing the NAND was worked for me too. But I have measurement problems, the voltage readings are not correct, and about 12% drifted down. I tried self calibration several times, but nothing changed. I think the "/config" partition may had some important calibration data, and now we lost them.
Do you have the same problem?

[Oscillator]

i have made the self calibration also.

i did only a short test with the built in 1khz test signal and the waveform generator.

the test signal shows 4.88V. (jumps to 4.96V from time to time)

when i set the generator to 3.0V then the measurement shows 2.96V.

i have no big experience with this scope but i think these values are okay.

[ubata]

Can you locate where the calibration data stored?
I haven't access to the scope now
Meanwhile, I had violent jitter on fast rising waves, even with scopes own generator. Like the picture posted by "tin head" here:

[Oscillator]

i have closed my scope already.

so i cant check the directories anymore.

but i am pretty sure there is a config subdirectory in the rootfs.

btw: flashing with dnw.exe gives the same result as flashing with the recovery sd-card.
the files are the same! so you might ask the hantek support if it wipes your calibration.
i guess thats the way it is.

but if the config data is missing, the system will complain at startup for sure!

i can double check the measurements with another DSO in the evening.

[ubata]

i can double check the measurements with another DSO in the evening.

Thanks a lot

[Oscillator]

i am finished with my measurements.

i took a hantek DSO5072P for comparison.

first i made a self calibration on both scopes.

then i measured an 1,5v alkaline battery.
a plain digital multimeter schows 1,5 volts for this battery.

my flashed 4102C shows 1.28v and the 5072P shows 1.6v.

all other measurements give the same reuslts:
the 4102C has too low values and the 5072P has too high values.

to my surprise the voltage of the 1khz test signal doenst show the same like in the morning.
in the morning i had 4.8 volts which is not bad at all.

now in the evening after a new self calibration the 4102C only shows 4.4 volts. the 5072P shows 5.36 volts.
all measuremts were taken with the same probe!

and both scopes show a jittered signal from the wave generator in high frequencies.
there is no difference!

so a long story short:

i dont think the new software has broken the old calibration.

@ubata:

what voltage is shown in your scope for the test signal?

[ubata]

. . . .

I think you are right. new software has not broken the old calibration. meanwhile "/config" partition does not belong to DSO4xx2C and even DSO5000P series.

for the scope compensation test signal pk-pk is about 4.8V that's not very bad
