Hello dear people,
I have a problem with my Nano VNA S-A-A V2.2
CPU is installed => GD32F303 CCT6
After a firmware update with DfuSE:
Nothing works with my Nano VNA S-A-A V2.2!
The screen of the Nano VNA is completely white after switching on.
I can no longer update via DfuSE, the DFu device (Nano VNA) is no longer found (USB device).
The short-circuit method VDD with BOOTO does not work !!!
However, I have access to the Nano VNA S-A-A via the ST Link V2, via this connection I can address and flash the VNA:
Data width: 8 bits
After the firmware update (nanovna-v2-201013-v2_2) still a white picture, nothing else.
I use this firmware for flashing => nanovna-v2-20201013-v2_2.bin
See also https://nanorfe.com/nanovna-versions.html
I shot the bootloader while flashing the firmware to address 0x08000000.
Is there a possibility that you email me the bootloader (thanks)
If the address for the bootloader is 0x08000000 => setting via ST Link / v2 => is that correct?
And the firmware then comes to address 0x08004000 is that correct?
Request for Info!
Thank you and greetings

Hello dear people,
Please reed manual for you V2 device (SAA-2) on
You use a false program. DFuSeDemo is for NanoVNA-H and NanoVNA-H4 only!!!
You need NanoVNA-QT from developer site nanorfe.com
Have You 2.8 or 4 inch display?
You bootloader is ok. You can not destroy bootloader with DFuSeDemo or with NanoVNA-QT
My bootloader is OK. How should I know that.
I flash the firmware as indicated with ST Link V2.
Nevertheless I have the errors as described, read my test => first mail!
What should I do?
The solution of the problem ?
Ask for info, thank you and greetings
Why use You ST-Link? FW update for V2 (SAA-2) devices is possible with programs NanoVNA-QT or NanoVNA-APP.
Please reed this. :
If You can not reed , please register in Forum of nanovna-beta-test

Happy New Year and the "nano-group" !
Thank you, too, for taking care, the instructions for "DiSlord" are great!
That's exactly what I was looking for.
I'll test it out today and send you feedback.
