I would like to update my NanoVNA 2.8"TFT with the Gecko-logo, color whide.

1) Where I find the flash-program?
2) Which files should I use for to clean (Only DMR-CLEAR_MEMORY_DFU.dfu?)?
3) Which firmware version do you recommend?

Info Hardware:
Kernel: 4.0.0
Compiler: GCC 5,4,1 20160919
Architecture: ARMv6-M
Core Variant: Cortex-M0
Port Info: Preemption thorough NMI
Platform: STM32FxB Entry Level Medium Density devices
Board: NanoVNA
Build time: May 5 2019 - 80:35:00

Thanks
Rob

Rob,
Your question was answered in the other topic where you asked it. Duplicating questions in different topics is bad etiquette.

Herb

Where is it?

So it's not important to clear the memory?
How to use?
For other questions, what can you tell me?

Rob,
Please understand that "DMR-CLEAR_MEMORY_DFU.dfu" will wipe your device and it will not work until you re-load whatever firmware you are upgrading to. It is used to give you a clean slate prior to installing your new firmware. Some users have not been able to upgrade successfully it they do not load "DMR-CLEAR_MEMORY_DFU.dfu" first.

All the tools and instructions you need to perform a firmware upgrade are in the links I previously provided. My best advice is that if you are happy with how the nanoVNA is performing to hold off upgrading the firmware until you see a feature or improvement released that you want.

Reasons you might want to upgrade:

1. TDR capability in firmware.
2. Operation up to 1500 MHz (at reduced performance).
3. DFU mode in firmware.
4. Change from 2 trace to 4 trace firmware (or vice versa).
5. Change to 800 MHz max operation for better device stability

Herb

In your web space I see many files, I need only DMR-CLEAR_MEMORY_DFU.dfu and an executable program, is it correct?
Should I find the program.exe?

..Again:
Reasons you might want to upgrade:
1. TDR capability in firmware. -> Can you measure the length of the coaxial cables?
2. Operation up to 1500 MHz (at reduced performance). -> No thanks (ugly dynamic... I imagine)!
3. DFU mode in firmware. -> So at the moment I can't delete the memory with the DMR-CLEAR_MEMORY_DFU.dfu file?
4. Change from 2 trace to 4 trace firmware (or vice versa). -> Better 2 tracks if it slows down with 4...?! With 2 tracks is the "aa" or "ch"?
5. Change to 800 MHz max operation for better device stability -> Interesting. At the moment I have an abnormal peak at 300Mhz on channel S21, maybe it could solve this problem (maybe it's a self oscillation).

Thanks..

I found the progam DfuSe_Demo_V3.0.6_Setup.exe, but it's a demo. Are there any limitations?

Is there a document that explains the update procedure for those who have never done this?

Thanks

Hi Rob,
the files you are looking for are here:

/g/nanovna-users/files/Firmware/All%20%28known%29%20publicly%20available%20NanoVNA%20DFU%20files%20from%20May%205,%202019%20through%20to%20Sept%2029,%202019/DMR

Have a fun!

I had found it. I had asked other questions.
Can you answer me?
Thanks

You've been instructed to read the User Guide several times.It's in the files section - dated Oct 2nd.There is also a DfuSe document on hugen's google drive page - look for it.
Please use the WIKI and FILES section on this forum.

Could you be kinder?
I just joined this system (which I don't know).
I don't speak English very well and this is already difficult for me.
If someone can put some links with useful information ... thanks

The answer is on page 19 of 29 of the document named 'NanoVNA User Guide-English-reformat-Oct-2-19.pdf' that you can find here:

/g/nanovna-users/files/NanoVNA%20User%20Guide-English-reformat-Oct-2-19.pdf

And of course see the wiki:

Rob, DfuSe_Demo_V3.0.6_Setup.exe is simply the tool provided by ST in order to program their STM chip used inside the NanoVNA.
You find it here:



Please take a look at this document named 'NanoVNA DFU Firmware Upgrade Guide.pdf' that you can find here:

Use Chrome Browser with its built-in language translation capability.
Then -? Go to the NanoVNA group webpage at:??? /g/nanovna-users/topics
Look at WIKI and FILES sections at left side of screen.

Italian translation of user manual is available at:?

Thanks. It's all very perfect. I already had these files.
But I asked other questions.

I repeat:
Does DfuSe_Demo_V3.0.6_Setup.exe have 30-day work limitations? Yes or no?


DMR-CLEAR_MEMORY_DFU.dfu is the only file I need to clear the memory?
Shouldn't these other files be used ?:
DMR-color-tweak-sept.29.2019_DFU.dfu
DMR_FILL Flash with FF DFU.dfu
DMR_M_10KHz_sept-13-19.dfu
DMR_nano-white-trace-test.dfu

Thank you again.

I collected some of this information near the top of Firmware Versions


.. which is at the bottom of Wiki Main Menu page
/g/nanovna-users/wiki

Really good! Congratulations for your job.
I read it well tomorrow morning.
Thanks

NO

YES

Shouldn't these other files be used ?:
DMR-color-tweak-sept.29.2019_DFU.dfu

NO

DMR_FILL Flash with FF DFU.dfu

Same as DMR-CLEAR_MEMORY_DFU.dfu

DMR_M_10KHz_sept-13-19.dfu

NO

DMR_nano-white-trace-test.dfu

NO

Thank you again.

Thanks!

Does DfuSe_Demo_V3.0.6_Setup.exe have 30-day work limitations? Yes or no?

No, "Demo" may be an historic artifact from the original author.
STM makes the software freely available to encourage use of its STM32 technology.

DMR-CLEAR_MEMORY_DFU.dfu is the only file I need to clear the memory?

Yes, but you need that only if some other firmware does not work after installation.

Shouldn't these other files be used ?:

Most folks do not install firmware for no reason.

DMR-color-tweak-sept.29.2019_DFU.dfu

Do you need to change trace colors?

DMR_FILL Flash with FF DFU.dfu

May be the same as DMR-CLEAR_MEMORY_DFU.dfu
It is for the same purpose, so not both.

DMR_M_10KHz_sept-13-19.dfu

Such as these were for enhancements, in this case 10KHz instead of 50KHz minimum.
I >>guess<< many enhancements are in Gen Hu Oct 2 firmware

DMR_nano-white-trace-test.dfu

Do you want white traces?
