Hantek DSO1152S - Wont boot after firmware update

<< < (5/26) > >>

tinhead:
btw, when you DSO anyway open, can you please make pictures of the other side of the PCB as well ? I wish to see how they made the isolation, and all these parts from isolation (ADCs, FPGA and SoC as well - but they known) are of the other PCB side.

WanaGo:
OK, did all the fix, however still got the boot loop.

Yes I updated the firmware as per the update menu on that latest update prior to all this, then got the boot loop.

copied the dso.exe file over as you said, restarted the unit and its still got a boot loop.

Any ideas?

Ill take photos of the other side while I await your reply

Regards
WanaGo

tinhead:
so you copied the dso.exe, changed the execution rights and when you kill the dsod and run /dso.exe it reboot then still after few seconds? Try to do this as well:

rm /param/sav/run*

and then try to run the /dso.exe

EDIT: once dsod killed there should be no reboot. It would be interessting as well to see what message is coming right before reboot.

WanaGo:
What I mean is, before I did what you said....

Start the unit up, Press Enter to get to linux prompt.
If I sit there it will reboot after about 20 seconds.
So to prevent that, I did the killall dsod.
I then put in the flash drive and copied over the dso.exe file I extracted from the up file.
i then did the rest of your instructions about the chmod etc, sync etc. running /dso.exe at this point starts the scope, no problem. All seems fine.
However rebooting the scope again, results in a boot loop like before.

Whatever is normally opening dso.exe it seems is not working.
I still get that same first warning message: "*** Warning - bad CRC or NAND, using default environment"
When I am looking at the UART.

Hope that makes sense

Opening scope now.

WanaGo:
OK here are some photos, both sides.
If you want larger res, let me know. Made smaller for the forum, but still 1280x853. Got them 4752x3168.
Its night here, so if you want better quality ones, let me know and ill take some in the day light tomorrow.
