Just checked, and all three of them are working for me.?

This is the easiest way, but anyway you need that the DFU mode drivers are installed, and that you insure the TinySA is in DFU mode.

Have you downloaded and installed the TinySA app on you PC??

Forget all the other stuff and use the app.

Put the SA into DFU mode and click on update. Use the DFU file, not the hex or bin files.

It works every time.

The step "The tinySA should now be updating with the tinySA.bin file using dfu-util-static.exe" does not work because dfu-util-static.exe does not execute.

I then copied the first command from the bat file and ran it in a Windows command window:

C:\Users\User\Downloads>.\dfu-util-static.exe? -a 0 -s 0x08000000:leave -D .\tinySA.bin

Invalid DFU suffix signature

A valid DFU suffix will be required in a future dfu-util release!!!

Cannot open DFU device 0483:df11

No DFU capable USB device available?

I then Googled tinysa firmware update and found the YouTube by Lockdown Electronics. This looked promising until discovering that dfuse demo is no longer available. All links go to STM32CubeProgrammer and the instructions are no longer valid.

I tried a few more YouTube video and gave up after about three hours of useless effort.

Are there any instructions for firmware updating that are relevant and understandable for Windows 11 in March 2022?

Karl,

please see comments below. For the avoidance of doubt, one feels your pain.

That means one or both of (at least) two things:

a) that the tinySA has not been put in to DFU mode, or

b) that there is no Windows DFU driver installed. The same firmware update mode is also used for the nanoVNA, and there is a clear-looking explanation of installing the driver under Windows 10 to be found at /g/nanovna-users/message/20899.

The DFU driver issue is not mentioned in the STM32Cube instructions [I don't know if this is an omission or the Cube programmer automagically sorts things out.]

The DFU Driver issue is also not mentioned (is missing) in the generic firmware update instructions to be found at .

I then Googled tinysa firmware update and found the YouTube by Lockdown Electronics. This looked promising until discovering that dfuse demo is no longer available. All links go to STM32CubeProgrammer and the instructions are no longer valid.

AFAIK there is no set of instructions for firmware update that specifically address Windows 11. As for understandable that rather depends on who the specific audience member is, their domain specific knowledge &c.

Full disclosure: this author is not currently using any Windows machine, 11 or otherwise.

If I do not forget I may add this whenever I do a next release

There is indeed no practical use (at least for me) of entering a hundredth of a Hz. ;)

“It is the mark of an instructed mind to rest satisfied with that degree of precision which the nature of the subject admits, and not to seek exactness where only an approximation of the truth is possible.” - Aristotle

That said, I always feel that errors that occur in one place where they are not a problem can be potentially serious in another place.

I feel with both John and @SleepingCat.

John is right, especially when it concerns measurements.
People can be so seemingly pretentious, although in most cases it's ignorance I'm afraid.

But I think @SleepingCat has also a point, another point.
If something goes wrong in an otherwise useless case (but you don't know why), what else can happen?

It becomes almost philosophical.
Are you from the school "If it ain't broke, don't fix it" OR from "If it ain't broke, you're not trying"? ? ;)?

Just my 2±1 cents,
