Hello Erik,

I am always getting a message in Chrome about "insecure download" and have click "keep" to download the file.

Could it be your website is on some Chrome blacklist.

Hans,

It's just Chrome being extra careful about the file type. From Erik's site,
it's OK so keep pressing keep!

Cheers.

It is http vs. https. Any site not using https is considered to be insecure. Which does not necessarily mean unsafe.

Looking at the code change, is the increased acceptable range for self-test 9 or is that actuality self-test 10? I ask because my occasional test 10 fails have gone away with this firmware update.

This new - and every - firmware update works well with my ultra. I update it with dfusedemo, under win10. Thank you Erik for this very good measurement unit!

Thank you. I just installed the FW with Win7 and ST-link utility.

But what are those 4.5.1 letters below the current FW version number? Are they remnants of the previous version?

Regards
.

Should be the HW version

Somehow I got an email? asking how I? did the updating. As I have confused two programs in my PC, it is best to answer here. I used STM32CubeProgrammer

First you need STM32CubeProgrammer, mine is a bit old but it works in? Win7. This? a link to several versions of it.
https://www.st.com/en/development-tools/stm32cubeprog.html
When I plugged in? the USB cable it was a bit tight and I had to press harder to? for it to make contact
Then I pressed the Jog wheel down and turned the SA on. USB cable was connected now. Windows noticed that a USB device was connected, but the display of SA stayed blank.
Then I clicked a button on the STM32CubeProgrammer and loaded the FW file and updating started.

The STM32 ST-LINK Utility is not the most intuitive or easiest program? to use, but it is small, so this does not really matter. There is only? limited number things you can do with it.
This is what I used, sorry about the confusion

Installed with no problems, all tests passed.

Should match the HW version number on the label on the back of your unit - mostly. I had the 4.5.1 on the display like you and on the back the label had HW Version V0.4.5.1.1

Hello All,

This has been discussed multiple times in the group but it is worth raising it again.

On both of the TinySA and TinySA Ultra firmware download pages on Erik's website, there is an excellent explanation on how to use STMCubeProgrammer to update the firmware on either of the TinySA variants. It also mentions the fact that the screen will go white on the original TinySA and blank on the Ultra when in DFU Mode.
For Windows, STMCube is definitely the easiest way to do a firmware update on the the TinySA (and NanoVNA-H & -H4).

After you update the firmware, make sure you do the following:
1. Clear Config
2. Calibrate
3. Run Self Test

If it fails Self Test, make sure you have connected the 2 SMA connectors together with a short SMA-M to SMA-M cable supplied with the unit and repeat the above three steps.
It is also recommended that you fit SMA M-F "connector saver" adaptors to each port to minimise wear in the device connectors.
These are much easier to replace than the device PCB mounted connectors:-).

HTH...Bob VK2ZRE

Strongly recommend running a self-test BEFORE firmware update for baseline.

Peter

If you have 4.5.1 on the display and 4.5.1.1 on the back
Where/when did you buy and can you post a photo of front and back?
